Having never handled one, educate me on this, do you have to use a tool or some type of gizmo to get it off to swap them out?

Sure, within the backstrap is a large pin that runs up the back strap that twists to lock and unlock. Its not the easiest thing to unlock it either as its a tight fit. Once you rotate the base of the pin it pulls out. Then you can pull the backstrap off. The backstraps are very snug, nothing loose feeling. They come with the medium size installed and the majority of people leave it that way. If you are satisfied with the grip of the Glock 17 then you would likly end up in the Medium camp. I prefer the small.

Try them out sometime, while Glock tops my list the M&P is second. :cool:

Just returned from the annual SWAT Round-Up in Orlando for the day. Glock was setup and had Dave Sevigny, Jesse Abbate, and Randi Rogers showing off the new 4th generation Glock. Asked Jesse if I could take a photo...she went and asked and was told NO!

The frame has a newer RTF pattern...not as many spikes/sharp as the current RTF. You get two additional back-straps with the pistol...without any back-straps installed you get what Jesse was calling the SF frame. Clip on the Medium back-strap and you have your standard tried and true Glock frame. Install the Large and you get the frame of the G20/G21 pistols. I was not very impressed with how the straps attach...looks like they would pop off really easy, but who knows.

Also new is a reversible magazine catch/release. Setup for right hand shooters you can use all the old magazines. Lefties will only be able to use new mags that will have double cut outs for the catch. I thought the new mag release looked hideous. Very large.

New as well is a double spring recoil guide rod assemble. Looks like a stretched out version of the G26/G27 recoil assemblies. Jesse claimed it reduces recoil.

Tomorrow they are going to let folks shoot them...unfortunately I will not be there.:crying:

Glock has been marketing the Gen 4 to police for a while, this is not the first time out in the wild. The Florida Highway Patrol has been testing the Gen 4 Glock 37 for months, and just signed on to go with them.

since when did glock ever made drastic changes to the original design? glock is like a porsche, it will never stray away from the original design.

FWIW the Gen 4 parts will not work on Gen 3 or 2 guns. IE- Gen 4 G22 slide barrel combo will not fit onto a Gen 3 G22. This was told to me yesterday during my Armorer recert class.

So much for my wondering if the recoil spring assembly was going to be backwards compatible?

Hey eringobragh (OP),

Did the 4th gen that you handled have fingergrooves or was it a flat front strap?

I saw a rumor on another forum that with the 4th gen., they were going to do away with needing to pull the trigger to field strip it. I'm assuming this is bogus since it would require a major redesign. But it doesn't hurt to ask.

Just a pressure fit. I would have thought they would have utilized the trigger housing pin to retain it. I'm hoping what we saw at SWAT wasn't a production model and the final product willl have a more secure method of retaining the back-straps!?!?

eringobragh
12-03-2009, 18:49
Hmmm, rather hoping it will have a more secure method too.
How would you estimate the grip size reduction to current Glocks ? Noticeable by look only or would you need to hold one to tell a difference ?

From the SF grip with no additional back-strap installed to the medium standard Glock back-strap installed, in my hands felt almost negligible. If you had very small hands I suppose it would make a difference. I didn't even bother with the large back-strap.

Hey guys, I've got a grand idea!

Let's all get hot and bothered and pissed off at Glock because of an UNCOMFIRMED story posted on THE INTERNET by somebody. Furthermore, we should ALL assume that this prototype/pre-release model that this guy is describing WILL be the final production model and that no further changes will be made! Yeah! That sounds logical!

...
...
...

I mean Jesus Christ guys... :upeyes::upeyes::upeyes::upeyes:

I handled and shot the smae Fourth Gen pistol that eringobragh did

Let me first say that eringobragh has no reason to lie and I'll tell ya that I know him and know he is as big a Glock Fag . . . ok, Glock FAN as there is out there. He isn't trying to run Glock down.

He is correct about almost all of his impressions

Just a pressure fit. I would have thought they would have utilized the trigger housing pin to retain it. I'm hoping what we saw at SWAT wasn't a production model and the final product willl have a more secure method of retaining the back-straps!?!?

He is wrong about this. More in a bit

The Fourth Gen Glocks will be introduced in a matter of weeks to the public . . . at SHOT Show.

As to this being a Proto and not being a final production pistol, you could be right, but not from what the Reps were saysing and not from what I saw.

This was not a Rapid Prototyped mock up. This was a working, shooting, handling pistol and it is not the only one. I shot it and watched while a line of folks handled/shot it.

Could things change? Sure, but I'd be very surprised if it is changed in the next five weeks.

In my opinion, I hope they change a few things based on feedback and "fix" it before it goes into full production, but based on Glocks history, I doubt it. It looks set in stone to me.

There are four main changes with the 4th gen and one minor one I saw, but don't know what it is for.

1) The magazine release. As has been described, it is now a reversible release. I asked about the previous "ambi" release and the change to all the magazines over the last couple of years and was told that the Ambi release has been shown to have been a mistake and is now a dead issue.

The "pad" of the new reversible release is larger in surface area.

The magazines for the new "Rev Release" has cuts on both sides of the magazine and are mirror images of each other. You can use all the old magazines if you keep the release on the left side of the pistol, but if you reverse it, you need the as yet to be released double release cut magazines. The new pistols will of course have the double cut magazines. No word if all new magazines will have the cuts, but based on Glocks history, I wold say with confidence that I expect that.

2) The 4th generation pistols will have a double spring recoil assembly, as described by eringobragh, it is a longer version of the G26/G27 spring.

It will not be designed to retrofit the older generations of pistols. The ring in the front of the slide is a larger diameter to accommodate the new assembly.

I've actually been asking for this for years. The double spring system works amazingly well and in actually shooting the 4th Gen G22 they had on hand, I can tell you that is sucks up a lot of the "bite" of the .40S&W transferred to the shooter via the grip. It felt kinda like shooting "+P" in a G17, maybe a little snapper, but not much.

If there is a 4th Generation G18C . . . look the hell out :D

3) The RTF texture on the 4th Gen pistol I examined is like a 1/2 texture RTF. As I like to carry IWB, I don't think this is really for me.

4) The main change of the 4th Gen is the interchangeable back straps.

As this is a Glock Forum, it should be a pretty easy thing for folks to wrap their head around. All 4th gen will be "SF". Meaning that the distance between the face of the trigger and the back strap is shorter. They do this by "under cutting" the back strap.

There will be two additional "add-a-straps" for the smaller framed pistols. I did not ask about the larger frames, but I ASSUME there will be one.

If you carry the pistol with no add-on, you have an "SF", small grip.

Add the smaller one, you have the traditional G17/G22/ect feel. Add the larger and you make you 9mm/40/357 feel like a G21

Where eringobragh got it wrong is that it's not just a whimpy snap on addition. The pistol will come with the two additional back straps and a longer back pin. To add a backstrap, you push out the rear pin, add the strap, which locks at the bottom and add the longer pin to hold the strap in place.

Personally, as an "SF", I didn't feel any difference (and I have smaller hands. They are very "Manly", just smaller then average :D), but you could feel a change adding the smaller add-a-strap. Not a big change and not worth the change, in my humble opion

The 4th Gen pistol looks pretty much identical to the 3rd Gen. One give-a-way is that the rear pin holes in the frame are larger and countersunk half moons.

The small change is on the inside. Pulling the slide off there is an as yet unexplained change in the frame. At the rear, on the left there is a hole in the frame. It's vertical and I doubt it's for "weight savings". Just so we know I know what a Glock frame looks like, I've been a Glock Armorer since the late 80's, have been through the "Advanced Armorer" and work on Glocks pretty much daily

the 4th Generation, I was told, is an OPTION. They will continue to offer the 3rd Gen pistols and you can have the 4th Gen if you like. Probably the best feature so far

In five or six weeks you'll be able to get all this directly from Glock and the Gun Press. Until then, feel free to consider it Internet Rumor. Don't care

Ah So! Jesse must have left the pin out for ease of demonstration! That makes more sense now. The booth was kinda swamped when I was there...she may have mentioned the pin and I did not hear her.

Thanks for dropping in...I was hoping you or Mr. Ross would show up here!

P.S. Yes your freakishly small hands are manly! Need a pic of you with a Wendy's Stack Attack burger! :tongueout:

Is it like the mini Glock recoil assembly's? If so the muzzle's must have had the recoil rod holes enlarged also or can you use the new recoil assembly's in the older generation Glocks?

One more question: Did the 4th gen 22 have the half moon cut in the front of the grip or is it gone like on the FS RTF's? Thanks for all the info.

BuckyP
12-05-2009, 10:55
Exactly. One reason I bought a Glock is that everything is simple and most parts interchangeable. I'm a lefty and have trained to use a right-handed gun, so a ambidextrous mag release doesn't interest me, especially if I can't use certain magazines!

I think the reversible mag catch is a better idea than the ambi. If nothing else, (as explained here) you can use the older mags as long as you don't reverse the catch.

The only complaint I ever had about the glock's design was the serrations on the slide because my hands have slipped when handling the slide before, so I'm glad that they changed that up for the 4th generation models. I would actually have to hold one before I can say anything about the new grip, but I am pretty much fine with how they are now.

Check that jhmayhem. The gen 4 looks to be going back to the straight serrations, so says all that have handled the gen 4. Only the gen 3 RTF2 "option" looks like it will have the fish scale looking serrations.

If the slides are interchangeable I would buy a bunch of new slides for my old guns.
:honkie:

What am I saying???

I'll just buy a bunch more new Glocks!!!
The reason I asked isnt for the new slides to old frames, the other way around. If the new grip is better than the old one, some people may want to change frames. What I wonder though, is if the grip and internal parts wont interchange, the is a good chance the slide wouldnt either. Maybe it will fit the rails, but it would be an easy possibility that the parts interacting with the frame mounted internals wouldnt work together.

I don't think it looked cheap or goofy at all. If one was just casually glancing over the table it would look like a current RTF with standard serrations. Once you looked closer you'd notice the RTF texture is different and that it had additional back-straps and that the mag release/catch was new.

The pistol felt fine...heck, although subtle, it felt good in SF configuration (no back-straps installed). It just doesn't scratch any itch that I have. I'll stick with the 3rd Gens...especially for carry. I think the RTF would shred my spare tire!

Just going by the picture I think the Gen 4 is definitely a step in the right direction and if the dual recoil spring setup proves reliable and soaks up the recoil like the H&K system you can count me in.

Edited to add: Hooray! I just realized it doesn't have an extended slide stop lever. Hooray!

About the compatibility and the slide saying "Gen 4", the Gen4 slide will obviously require use of the Gen4 recoil assembly/guide rod because of the larger hole in the slide for it. Also, the cut-out in the barrel lug that the guide rod fits into will have to be wider for the new guide rod, so the Gen4 slide must be used with the Gen4 recoil assembly and barrel.

I'm interested in how the backstraps attach. Glock doesn't want regular users to do anything internally with the pistol, so I doubt that removing the trigger housing pin would have anything to do with attachment of the backstraps. From the picture, it looks like the area around the trigger housing pin is raised so that the backstraps just click over it. It also looks like before the backstrap clicks over that raised button, it hooks over the bottom of the existing backstrap so that it's attached top and bottom.

AgentAdam

Someone already stated there is an extended connector block pin for the additional back straps. The rear pin even looks beefed up as in larger ,and maybe even steel, compared to the small plastic pin of the gen 3. If you pushed rear pin out with the extra pin the internals would stay intact.

The space around the rear pin is probably sunk with the bumped up part being on the inside of the backstraps.

The sights seem taller. The barrel end, guide rod tip,and sights look super imposed on the pic.

Recently saw a few pictures of the new Gen4 and got some info. The mag release is larger which is good but, I hope it doesn't interfere with current model holsters. (hopefully they thought about that) The captured steel double spring guide rod is nice, maybe less recoil too? The interchangable backstraps are all curved. I was told because Mr.Glock said "The backstrap is supposed to be curved". For flat backstrap fans, I'm sure an aftermarket company will make a flat backstrap. The grip texturing will be good, in between the old style and the RTF2. There will be an even newer mag design for the new reversible mag release with a relief cut on the right side of the mag tube.(3 cuts on the tube). Also heard the ambi mag release on the G21SF is going to be phased out. The first release is the 17&22, then 19&23. I'm waiting on the 21 to buy as a duty gun.

12-19-2009, 12:02
The the older mags will work fine if you have the mag release set up for a right handed shooter.

So the news is glock will now include a double recoil spring in all their new gen 4 models. I wonder how much of a difference the felt recoil will be in the .40. We all know that round is snappy and for some can beat up a shooters hand after many shots fired. If the double recoil springs will reduce the recoil the g17 will probably be really smooth the shoot. Anyone here know first hand how it shoots?

AgentAdam
12-24-2009, 06:42
I doubt a solid steel guide rod would "solve the problem" with weapon mounted lights. I would rather have a glock that will still function when the guide rod melted and flew out after 1000 rounds than a steel one bent,cracked and jammed up.

The new guide rods are still polymer, or at least a hybrid and still allows flex. Just look at you 26,27,33 recoil assembly. The main shaft is polymer with a steel tube over the last half to guide the larger spring. I think the double recoil spring is more of a cycle rate/recoil issue and the guide rod is just the aftermath of it.

Lots of companies are going over to the captured polymer recoil rod like the Beretta 90-Two.

I don't think any amount of springs or variations are going to reduce the recoil of the gun no matter what. Laws of physics apply every time. I'm sure there are other reasons why Glock is using the Dual Spring system on the Gen4 frames. BTW, the polymer rods are just fine. Watch the 1000rd in 15 minutes torture test. somewhere around 900 rds the guide rod finally gave it up only because it melted, BUT the gun KEPT FIRING to the last bullet left the barrel! I've never had to replace a rod, and I don't recommend the metal rod for a metal spring, you're just asking for trouble and more $$$ to spend replacing them again and again.

Supposedly all gen4 will have the dual setup. The only pic out is of the full size 22 with one.

There is nothing crappy about the polymer guide rods. The only purpose of the guide rod is to guide the spring, period. Nothing crappy about Glock polymer frames either.

They did remedy a slight issue by reinforcing the old polymer rods with some glass-reinforced nylon material, or something like that. I've had ZERO problems with all of mine after thousands of rounds.

Does anybody know if the interchanageable backstraps on the gen 4 Glocks are going to be optional like the RTF Glocks, or if it will be standard??

Gen 4 itself is an option, on the 17 and 22 only so far. Gen 3s will continue to be made. If you get a Gen 4, it will come with changeable backstraps.

i read that article-what a load. glock isn't going to cease production of the gen 3's as they are prob the most popular guns in the world.

plus the article mentions the dual recoil spring is for reliability-nope, it's to reduce recoil. glocks are already reliable.

the article also mentions a $700 MSRP-you can look at a glock order form, the gen 4's are the same price as the current glocks.

this article is totally off...

Not according to what has been stated, the OD is larger on the front.
I am repeating what I have read, I have not measured one.

If it is only the front of slide that is different, it should be easy for glock to retrofit old slides to take new recoil spring. This is potential solution to some of the problems with G22s and G23s, especially when used with lights.

Also the slide alone can be sent regular mail, so would not have the high postage costs.

howdy guys, long time reader, first time poster. :) I never bought a glock because it felt bad in my hands, it felt too thick which I know has been discussed at length on this and other boards. I was leaning towards the sig's as I like their feel MUCH better, but I know glock is an outstanding gun with a proven track record so I am researching the gen 4. My question is this;

As I look for info on the 4th generation of 9mm, I cannot find the specs on the grip size, specifically the width from side to side and front to back. I held a subcompact 9mm yesterday (2nd or 3 gen I don't know) and even that felt rather "bulky" in my hand. Not being a glock afficianado, will the gen 4 be smaller than this with the new backstrap system or no? Is the option of having NO backstrap on to further reduce the grip size an option, or will there just be an opening on the back of the grip? I've read about SF which I assume means Small Frame correct?


Thank you in advance for any help you are able to provide and have a good day.

As I look for info on the 4th generation of 9mm, I cannot find the specs on the grip size, specifically the width from side to side and front to back.

The way I read it from those that held the gen4 is that the standard Gen4 G17 grip without any of the backstraps installed will be the equivelent of a SF grip, even though there is no SF grip for the 9mms. So I interpret that to mean that the stock gen4 grip with no backstraps will be 3mm shorter from front to back than what the G17 grip is now. Most people notice the decrease in the trigger reach, i.e. how much finger will rest on the trigger. Short fingers/small hands might like the possibilities here.

Installing the "small" backstrap is thought to be bringing the grip back to what the G17 grip is now.

Installing the "large" backstrap is thought to be bringing the grip to equal the larger frame 10mms and 45s full size grips (ie slightly bigger than what the G17 is now).

Thats about all the rumour I can contribute. :cool:

You can look on Glock website to get most of these dimensions on these various current models.

Tall Pine,

The Gen 4 comes standard as 'small'. The 'small' is permanent. You can add a 'medium' or 'large' backstrap on top of the factory small.

I put on my medium backstrap in about 30 seconds today. Disassemble tool included works OK. The tool is used to drift out the housing pin (and to put in the replacement pin).

Spreadfire Arms
12-29-2009, 16:00
i just physically picked up a new Glock Gen 4 today. it does not appear to be Laser Max compatible as it has a similar recoil spring system to the mini-Glocks.

it has different stippling than the RTF and the Gen 3. the slides are marked "Gen 4." has a lower profile magazine release which can be switched to the other side for lefties. magazines are slightly different in the fact that the cutout where the mag seats into the magazine catch is metal lined.

of course there are the two additional backstraps. as it has been explained to me the original backstrap is the same as the short frame (SF), the medium backstrap is the standard grip on the Gen 2/3 Glock 17/22, and the fat backstrap is the same as the Glock 20/21.

from my understanding these pistols are only currently being made for the full size .40.

I agree and thats what I explained in my post. I used the term small backstrap were you used the term medium backstrap.

With no backstraps, the grip is said to be smaller than it is now, like an SF frame would be to a G30. Adding the medium (or as I wrote "small") backstrap would bring the grip equal to what it is now. So in essence the Gen 4 should yield a grip size smaller, the same, and larger than what the grip is now on the G17 & G22.

According to my most trusted friend:

"Saw some folks were asking about the backstrap. It measures approx .040"
thick and is not flush. I put 500 rounds through it tonight and the
backstrap was never an issue. I do not think it not being flush will be an
issue due to its length."

I consider the new recoil spring as Glock's attempt to achieve perfection is a recoil spring assembly. I would guess the dual spring would act like a variable spring, both strong enough at the end of slide travel to reduce felt recoil, while light enough for quicker slide return, thereby reducing muzzle flip. Those that have tried the new G22 really like it.

Personally, I will be using my new G17 Gen 4 without any extra backstrap, so it's a not-issue with me.

I've purchased the Glock 22 Gen 4 and have fired it at the range with spectacular results. I want to say a big thank you to Don Anderson at Ed's Public Safety in Stockbridge, GA. He and his staff are very friendly and knowledgable. When I ordered my gun it was delivered at my local dealer the next day here in North Carolina. At the range I shot 500 rounds using a combination of Federal 180 grain FMJFN and Speer Gold Dot 155 grain HP, no matter the grain I shot within 2" of target at mainly two distances 5 feet & 7 feet. At 10 feet I was within 3" of target. These were averages, yes there was the occasional outlier. At 20 feet I struggled, where my pattern was more to the left and 6" to 7" from bullseye. I give it user error not gun error. However, I do hit bullseye pattern at 20 feet with my 22C or compensator. I still feel less recoil on my 22C than on the new Gen 4, but let me add it is a significant difference over the Gen 3 models. The double coil system on the Gen 4 system is similar to the H&K, its a great improvement on muzzle flip. Now, a real significant improvement is its "pointing" ability. I no longer have to adjust my sights up or down it feels natural and aligned when I simply aim. I believe the customized backstrap helps with the target acquisition. Also, its extremely easy to change. It comes with a tool that you push the pin in or out to change back straps. No place to keep the pin though, I'm sure an after market product will come-out to hold the pin in a plug like the ones found in the M&P's with their changeable back-straps. I noticed too that internally the block is beefier and their is less flex on the frame than older models. The mag release is very smooth to operate. Glock has done it right with the new Gen4. I would highly recommend this weapon with its advanced features.

To bad they didn't change it more like an expensive German brand of pistol I can't mention(no flame intended, I feel I have to point down too much, feels awkward to me)... although if they did it would really screw with all current Glocks owners that like the grip angle(I don't but still like Glock) I think Glock did a good job on the new Gen 4. I think it would be nice to see a more beveled slide instead of it being so square, but the decreased slide material would probably affect functioning making the slide to light...IMHO. I am looking forward and wondering when the other models like the G38/G39 will get this nice makeover.

What I'm waiting for is an official updated parts list from GLock that will show beyond a doubt what parts are and are not compatible between the two.

Thinking mainly connector and trigger springs, but also internal slide parts. Now their is no reason those SHOULD change, but just to make sure Glock did not do any "Updating" as they had a new slide that did not have to be compatible wiht old models anyway.

Measurments of the gen 4 vs the gen 3 measured from the back of the trigger guard to the curve of the backstrap.


Gen 3 = 2.242"
Gen 4 with no added backstrap = 2.154
Gen 4 with medium "M" backstrap = 2.245
Gen 4 with large "L" backstrap = 2.320

These measurements are for comparison only and are not intended to be any sort of official specs. I made them with a set of dial calipers from midway so although I was careful to be as accurate as possible there is some room for error.

I also measured the width of the grips and the Gen 3 was 1.185" wide while the Gen 4 was thinner at 1.178"

I'm sure there are many more measurements that people will be interested in, but the main point is the Gen 4 grip is shorter front to back and thinner side to side than the Gen 3 grip.

The Gen 4 has had the grip pushed in (vs. the Gen 3) & uses a modified trigger housing... much like the G-21sf. I have been wondering if that would make the trigger pull heavier.

All sf models I have ever held seem to have a much heavier pull than the comparable non-sf models. I believe that the modified housing tilts the connector back a few degrees... making a 5# connector work more like an 8# one. A Glock armorer told me that was not the case, but I have my mind made up & don't want to be confused with facts! :whistling:

I don't think I'm violating any forum rules as this is a free online mag with a very good review of a Gen 4 G22!

As for a Gen 4..... I'll wait for the Gen 5! Maybe the Gen 4 will usher in something like the "pre 64" Winchester Model 70 thing. Keep your early Glocks!! I sure wish I kept my pre-64 Model 70 Super Grade 375 H&H. I could sell it now and buy 10 Glocks! It got attention at the range and it would absolutely knock down any large animal I ever shot with it! But I digress....

The recoil feels more "dull" compared to a Gen3, but it's not drastic. At least not in my opinion.
The thing I like most about the Gen4 is the SF grip you get, when you don't install a backstrap.

I've tried to skim through the 7 pages of posts in this thread, but can anyone confirm if Glock is doing away with Gen 3 models all together? I hope not.

The Gen 4's look okay, but I'm not seeing anything earth-shattering in terms of improvements. About the only true advantage I see for the Gen 4's are the dual recoil system, which I do wish Glock would've made backwards compatible for the Gen 3's.

I'm not saying I wouldn't buy a Gen 4, but I'm really not seeing much here that makes me feel like I need to ditch my Gen 3's and "upgrade."

I understand Glock feels the need to be competitive with the M&P's and XD's, but the changes really seem pretty superficial to me. Think I'll cling fast to my Gen 3 models for now unless someone convinces me otherwise.

Even if they did completely do away with the earlier generations, I am sure there are enough Glocks on the street that you will still be able to find the older models for at least the next 20 or 30 years or so. If you don't want to upgrade, I wouldn't worry about it.

I think Glock will take a "wait and see" approach to see which guns are really selling. The Gen3 RTF2 guns are good, but shooters seem to prefer the Gen 3's. Whether or not Glock's customer base accepts the Gen4 or not remains to be seen. Noone REALLY knows what percentage of new gun purchasers would choose a Gen4 Glock over a Gen3 Glock or other manufacturer's model (i.e. SIG, S&W, or SA/XD). Even when Glock brought out the Gen3 guns, it was just a new frame shape (same internals), a much-improved slide finish (same internals, but with the LCI extractors), and Glock-brand Night sights available. They also re-designed mag followers. Nothing really major, but the Gen3's became the "benchmark".

Glock's SF models have been a mixed bag. The 21SF with the ambi-mag release was stillborn, and the G30SF's issues have been the subject of much discussion here. I think Glock is onto a good thing with the SF concept, and I don't see these guns going away.

The Gen4 offers the interchangeable backstraps and an improved recoil spring arrangement. Whether or not shooters who buy Glock pistols will want interchangeable backstraps is impossible to predict. What the Glock brand represents to shooters is simplicity and utilitarianism. Would a shooter selecting a new pistol choose a Glock Gen4 over an S&W M&P if both guns offered interchangeable backstraps? Or would that same customer select a Gen3 Glock over the M&P because they wanted a Glock, or the M&P because they wanted something that wasn't a Glock? In other words, will the market ever perceive a Glock pistol - no matter what it's feature list (Gen3, Gen4, RTF2) -as anything other that a Gen3 Glock, because of the image that Glock's brand-name represents? It will be a few years before we know the answer.

I think Glock's top priority should be to fix the LE market issues with the .40 G22 and G23 - decisively curing the malfunction issue with rail-mounted lights. If it takes a Gen4 design to do that, then so be it. The interchangeable backstraps will take care of Officer hand-size issues. The gun will still present all of Glock's existing advantages - easy armorer maintenance, no factory-only repairs, low parts-count, and extreme durability. Regardless of what Glock does with the Gen4, though, their primary competitors will be S&W and SigSauer. The M&P offers something Glock cannot - a magazine disconnect safety, and non-trigger-pull disassembly. SigSauer also offers something Glock cannot - optional trigger actions (DA/SA, DAK, DAO), and non-trigger-pull disassembly. SigSauer also offers a new product line with interchangeable grip frames (the P250), going WAY beyond interchangeable backstraps.

It's a three-horse race now. I'm excited.

Looks good, KKM is nice but very expensive. How do you like the new mag release and frame texture?

They're both excellent! I never handled any of the other RTF frames before but have heard they were uncomfortable. The current texture works perfectly for me as a balance between solid grip and comfort. I had to re-grip the Gen3 G23 after almost every shot. Not so with the Gen4 G22 at all.

I would have loved a factory G31 barrel but couldn't find one in stock. (edit: apparently I didn't look hard enough. Lonewolf has them in stock for the price of a KKM through Brownells) The less expensive alternatives to KKM should be equally as compatible though.

I will say this: I am not a fan of the new guide rod. I have had it cause the slide to stick during field stripping a few times, and this scratched up/chewed up the inside of the frame, just slightly forward of the rear part of the rod. As seen in the following picture, the guide rod often ends up like seated in the slide but otherwise completely free-floating.
http://farm5.static.flickr.com/4040/4517558331_937be91812_o.jpg
Note that it is not touching the barrel at all. You can see the front end protruding out the front of the slide, which should only be happening once the slide is on the frame. Not really a big deal as long as you keep an eye on it and make sure it's not like this when you slap the slide back onto the frame.

I posted a question about the recoil spring taking polymer material off of the frame, and just wondered how many of you are seeing this? I'm a little disappointed by it, but if it doesn't get worse it won't bother me that much. I'm guessing that it won't affect function.

Yea, I actually just handled one at the store for the first time. Slide got stuck on the frame it was weird. Never experienced that with a Glock before. I ended up cutting my hand trying to fix it and remove the slide. But once I was able to get the slide off It seemed like the new duel recoil spring was abit flimsy. It may just be me I'm not sure.

What is it like to fire it? Does it feel any different? :dunno:

Racking the slide didn't really seem any different then a Gen3.

I do admit I like the new grip texture and mag release. I'm not certain on the Duel spring system yet though.

Rusty,

I did notice identical marks yesterday, but they aren't what I was talking about. 5/6 of my Glocks have those.

In my Gen4 I was getting some itty bitty scratches in the circled areas of this pic. (pic is of a gen3 just to show where I was talking about.) Rear disc on the guide rod seems to occasionally snag on the "lip" of these spots sometimes during field stripping. After noticing these spots with metal showing through on my Gen4, like yours, and on all but one of my other Glocks, I think these little scratches I was talking about are nothing of concern. I think I was just really used to the type of guide rod found in the G19 which is almost impossible to seat incorrectly and won't snag on anything.

There is nothing wrong with your gun. The polymer simply didn't fill all the voids around the metal. Many Glocks are like that. It doesn't mean anything and won't affect the function of the gun.

I had a quick look through this thread, and didn't see an answer. I'd like to get some spare goodies at Brownells. Is it safe to assume (there's that word :embarassed:) that all the slide internals are the same as Gen 3, except for:


The slide itself
Recoil spring
Barrel (?)

Thanks!

Although I have not compared them, I would assume yes as well.

All three are different in the Gen4. The slide, at the very least, has a larger hole where the guide rod seats at the front. The recoil spring is an all-metal two-piece design that requires the larger hole in the slide to work at all. The barrel has a slightly larger cutout where the guide rod seats at the rear for assembly. At least on my aftermarket barrel, this has made absolutely no difference whatsoever. The Gen4 guide rod seats just fine in the Gen3 KKM barrel lug for assembly.

Both barrel manufacturers I contacted stated that the old (Gen3) barrels are either "the same" or "will interchange" with the Gen4 barrels. I got my Gen3 KKM barrel from Brownells (model G31C1) and it has been working 100% for 1,000 rounds so far.

Not sure. I know the Gen4 works with the usual aftermarket wolff firing pin springs, so my GUESS would be that there is no change to those parts and the spring cups should be the same.

I agree. But for me, the jury is still out on the double spring recoil system. I can only imagine it's an improvement, but I don't think I have ever heard about any problems with the Glock's Gen1-3 single spring system.

It makes scense on a sub compact since one short length spring by itself may not be enough, but on a full size? I'll wait just a bit to see how it functions in the real world before pickin one up.

02-19-2010, 22:57
yea I'm not sure why the switch, but from what I've heard so far, it works. Heck, XDs have a dual recoil system, though XDm switched to a non-captive single spring (not sure about the 3.8" I didn't even think about it when I saw them in the shop). I guess it's just one of those things companies like to change.

Numerous threads about issues with Gen 3 G22s with lights hanging on them. From what I understand, the new recoil spring is to help address that. I guess time will tell.

Perhaps the weight of the light system off balanced the front end enough to off balance it. Never heard of any issues without the light and personally, never experienced any problems with the light on it myself.

I've seen a lot of claims and concerns regarding the Gen4 killing compatibility in Glock's lineup, and I finally got around to fully stripping and swapping parts myself and added the posted experience of another GT member to get a full list.

Parts compatibility between 3rd and 4th Gen:

I have personally swapped (G22):

KKM Gen3 barrel
Firing Pin/spring
Spacer Sleeve
Spring Cups
Firing Pin Safety/spring
Extractor
Extractor Depressor plunger/spring
Spring Loaded Bearing
Slide Cover Plate
Rear Sight
Front Sight
Slide Lock/spring
Locking Block
Connector
Slide Stop Lever(extended)
Trigger w/trigger bar
Trigger spring

That leaves the incompatible parts at:

1) Slide
2) Recoil Spring Assembly
3) Magazine Catch/spring
4) Trigger Mechanism Housing

I thought the Gen 4's barrel lug has (& needs) a larger notch for the recoil spring guide rod.

Also, how can the Gen 3 trigger housing fit in the Gen 4 frame when its housing has been reduced at the bottom like SF models... because the frame grip area was reduced?

I've posted at least a dozen times regarding the barrel, probably several of which are in this thread.

After double-checking with JBP55, he forgot to mention that he'd "modified" his trigger mechanism housing.

If parts require any modification at all, I don't count them as compatible.

I have verified the other swaps myself (trigger bar, trigger, and trigger spring) and corrected the original post.

Rusty -

Sorry I missed your post about the barrel. So they are not the same, but will "work", per your tests.

In looking for your comment about the barrel, I noticed you said that the new guide rod/spring assembly is "all steel". Isn't the rod itself plastic as in the sub-compact models?

Maybe I'm out of the loop having not bought a new Glock for several years, but on the two I bought yesterday (only one of which is a Gen4), the front sights look like they're plastic, but instead of the old pin press fit to spread the bottom of the sight, there's a small screw (looks just like the ones used by the Meprolight night sights I've installed on other Glocks) holding the front sight...and it looks like that screw extends all the way up to the top of the front sight. Has this been standard for a while?

yep. I'm not sure when exactly but I think all gen3+ have new screw on sights. Smart more in my opinion.

I guess they improved the front but took a step back on the rear. I shot my Gen4 17 today...and like most (but not all) Glocks, it hit to the left for me. I used my MGW pusher to drift the rear to the right a bit, then decided to pop it out and maybe try a Glock adjustable rear I had left over from another gun. While trying to push the rear sight out, it began to deform and basically tore apart on the way out. The metal bit that helps hold it in place was left behind and had to be tapped out with a punch and my Brownells gunsmith hammer.

I've replaced factory sights (typically for night sights) on probably a dozen or more Glocks for myself, family, and friends, and never seen that happen before. Fortunately, I always keep parts...so I just slid in another (older) Glock rear fixed sight. If it's a keeper, it'll end up getting night sights anyway.

The new one is all steel and is totally different from the ones currently in Gen3 subcompacts. Not sure why they did this.

Edit:
Found my answer...
Quoted from Western Shooter Blog Archive;

"As of right now, February 2010, the Glock GEN 4 is only available in the G22 and G17. The G22 is chambered in .40 S&W and is considered a “standard” size Glock. The G17 is chambered in 9mm (9×19mm) and is also considered “standard” size. Glock is planning on releasing the GEN 4 in all of their models. As far as time frame goes, they will release the G19 and G23 this fall. The next models have yet to be determined and I was told their release will be based on demand."

Would it be stupid to assume that it could be up to a year, and possibly even longer before I even see a Glock 20 (10mm) released in Gen 4? Or am I just being a pessimistic whiny little b****? I would love to buy a Gen 4 20 today, but the gosh darn thing doesn't sound very promising for my immediate future.

Dude! Do some reading. The only change I'm aware of post-production on the Gen4 guns is a few revisions of the new dual spring recoil assemblies. Some people had function issues with the original dual spring assemblies with "weak US market ammo".

Glock also changed extractor design about the same time. They also started including them with gen3s but it was introduced when the gen4s were introduced. So, that's why some people are changing to Lone Wolf extractors to see if that helps. Thinking is maybe the extractor is contributing to the problem by not extracting!

Glock even told customer they had a batch of "out of spec" extractors. Is it that or a bad design?

=======

"weak U.S. market ammo" is bull. Any reputable gun should be able to fire factory SAAMI spec ammo. Period. Winchester white box is loaded to SAMMI specs. If Glock can't fire that, it's Glock's fault.

========

And I'm a huge Glock fan. I've only owned Glocks for the past 21 years. Right now I own a Gen3 Glock 19 and a Gen4 Glock 26. I sold a Gen3 Glock 26 to get the Gen4 26 -- which had several FTEs in the first 300 rounds. :steamed: Since springs didn't change with the Glock 26s, I'm leaning towards the extractor theory myself.

But if Glock has screwed up, don't be mindless fanbois about it. I'm sure they will fix it, but don't blame the messengers and don't blame ammo. My Gen3 Glock has no trouble shooting factory SAMMI spec ammo. If Gen4s can't, it's the Gen4 fault (somewhere in the firing process), not the ammo's fault (which didn't change).

When Federal Ammunition introduces a product like Federal Champion 115-gr FMJ 9mm ammo to the USA market, the lowest powered ammo ever offered, then it is an ammo issue. It won't function in a new Gen4, New XD or New Kimber. Champion would not even function in my Gen2 G19 when I installed a brand new factory recoil spring assembly to test.

With it's latest 9mm offering, Kimber recommends only 124-gr and higher full power service ammo.

Sometimes it is an ammo issue. Sometimes it is a shooter issue. Sometimes it is a recoil spring issue.

Try not to forget all the issues stated here that new shooters have had after buying a Gen2 or Gen3 "C" model 9mm Glock.

SAAMI regulates maximum pressures, not minimum, cheap loadings. Winchester USA (PF of 136.85) works fine in all Glocks. It is far hotter than Federal Champion (PF of 129.38). Glocks, being Military pistols, are designed around the 124-gr FMJ NATO round, PF of 146.94.

Nope, its a combat pistol. Ready to go out of the box. Its not a 1911 or Revolver that have a high number of internal parts and are delicate to different situations and break ins.
