Glock 27 Feeding Issue

[Jonas101]

So I had 100 rounds to shoot at the range today. The first 50 were fine, the second 50 weren't. I kept having a feeding issue with my factory factory mags. The only change to these is the Pearce +0 extensions. Rounds 1 through 7 were fine. The 8th round, on both magazines, multiple times in a row, kept getting stuck on the top of the chamber. Upon closer examination, the 9th round was almost OUT of the magazine. It looked like it was trying to push the 8th round straight up, causing the bullet to hit the top of the chamber and causing this problem. :steamed:

The only other way to describe this is imagine your loaded magazine. All the rounds being properly loaded into the magazine. As you shoot through the mag, instead of them feeding out of the mag at the proper angle, they progressively want to exit the mag pointing up. The angle gets progressively worse as you shoot through the mag finally causing a failure at the 8th round. EVERYTIME. :shocked:

Anyone else have this problem or know what is causing it and how to fix it?

I have a new mag that wasn't having this issue, and I was using WWB.

Thank you in advance!

Replace the spring on the bad magazine(s).

[Jonas101]

You've heard of this problem before? Is it possible for both factory mags supplied with my pistol to fail at the exact same time?

Do you think it could be anything else failing? Any help would be appreciated.

[Kentak]

It's not the springs.

[NEO Clevelander]

Which followers are in your mags?

The most current appears to be the #8 follower.

I've read of a lot of issues with other-than-#8 followers.

[crankbait11]

My friend had at one time 2 different NIB 27's and both jammed consistently with any of the 23/22 mags. He got rid of the first one thinking it was a lemon and got another one, but it did the same thing, so he got rid of it too. He tried 4 or 5 different new mags and none worked. He never had any issues with the 9 rounders and some of his had pearce extensions on them. I really wanted to play around with the followers on his to see if I could fix the problem, be he lost hope with them and moved to something else before I got the chance. :upeyes:

[skyboss_4evr]

And you know this for a fact, how?? It could be worn or bad followers, but it could also be the magazine spring! Many feeding issues can be attributed to bad/old mag springs. In fact, my brand new G38 had ONE magazine that caused failures to feed on occasion. I installed a new GLOCK spring and the magazine has been flawless since.

I take exception to you totally dismissing my suggestion outright when it very well could be a bad magazine spring.

Calm down. You'll notice I answered *after* Jonas101 said the problem was occurring with both mags at the same time. While both *could* go bad at the same time, it's unlikely. I'd want to know if the followers are different from his new mag which does not have the problem. If so, I'd swap the follower out with one in the "bad" mags and see how it does. If that's not conclusive, then I'd put it back and swap out the springs.

He described the problem as the round nosing up to catch on the barrel hood. I'm not sure how a weak spring (they don't get stronger with age) could cause that.

If springs were responsible for as many malfunctions as posters here seem to say, then I have to wonder about Glock's design being so sensitive to spring function. Either that or Glock is negligent with QC on their spring suppliers.

Honestly, is there any other pistol make that has as many apparent spring problems as Glock?

Very well. Jonas did mention in the OP that he had one magazine that was NOT acting up. So Jonas... what marking is on the followers of the bad magazines?

[ALL GLOCK]

If the followers are #6 or #7, get them outta there and put in #8s

Did anyone notice he added "Pearce Extensions" on the mags with the problems, and the factory stock mag worked flawlessly???
Try keeping your Glock stock for absolute reliability. Get some more factory mags and don't ******* around with them...and bet all of them will work:thumbsup:

[KAPSIG1]

I have a G27 Imported Date July 10th 2001

I use 22 mags from my G22 Imported January 20 1992 to mags bought now no issues

I use pre and post ban G23 mags no issues
I use pre and post ban G27 mags some with PG-39 (Pierce) extentions and Glock +2 pre and post ban no issues

It has to be something else or I have a G27 that just eats everything I feed it.

I use WWB from China mart at the range allot as well.

[Jonas101]

Sorry for the slow replies, I was watching a movie. These magazines are are about 2 years old. They came NIB with the G27. I added the +0's the day I bought the pistol. I've had 1 feeding issue before today, and it was the same problem. Now BOTH of my original magazines are causing this problem. The magazine I picked up about a month ago doesn't have this problem. ALSO the issue only happens on the 8th round in the magazine. EVERY TIME. For example, if I have 5 rounds in the magazine, the problem doesn't occur I have to have more than 7 rounds loaded in the magazine for this issue to occur. It is definitely a magazine issue.

I have the gun in the shop for the certified GLOCK armorer to look at. I just left it at Top Gun in Houston when I was done shooting. I should know more by tomorrow afternoon. I'll keep you guys posted. Thank you for all the input.

I seem to have one of those G27s too. Others seem to have problems, but I've fed my 27 a lot of cheap ammo, and never an issue of any kind. I have a range mag with a +1 Pearce on it, and it functions flawlessly. My carry mag has a GAP floorplate (same as stock, basically) and never an issue.

That's why I tend to blame followers when people have issues. The #8s seem to never have a problem.

When I first saw the title of this thread, i thought you were going to be complaining about the price of .40 ammo... :tongueout:

Anyways, I don't think I could have put it any better than Mick did. Just leave everything stock and I'm pretty sure the problems you will have with GLOCK handguns will decrease dramatically or stop all together (which is more likely the case.) GLOCK designed their guns the way they did for a reason. I was going to say everything almost exactly as Mick did. Let us know what happens either way you decide to go with it. Good luck man!

:fallenofficer:

[Jonas101]

I just find it weird that both failed at the same time. The followers do have A LOT of wear showing. Divots, etc. I'm comparing this to the newer mag I bought that looks and acts flawless.

It's just weirding me out that both are having this problem on round #8. Before this, the pistol has been flawless. SUCKS. I'll find out more tomorrow when I pick the gun up from the shop.

[ALL GLOCK]

What is the # on the followers??
If they are 2 years old , I bet they are #7 followers. They are the worst!

[NEO Clevelander]

Yes, #7s are notoriously bad, and seem to have been rather quickly replaced. The #6s seem to have had a larger run.

[Doug S]

I had a used G27 that had occasional malfunctions with the Pearce extension. It worked fine with the factory 9 round mag. Would also occasionally malfunction with G22 mags. I think all of the malfunctions (probably 4 or so) were a failure to go completely into battery. This was also with the Wolffe + power springs.

[cole]

Springs likely okay. Try replacing the follower. It's $1: http://www.ombexpress.com/category~cat~426501614.asp. #8 are current and on all of my G27 and G23 mags. My Glock 27 has run 100%.

[Kentak]

Wait a minute. 8th round from the top, or 8th round from the bottom? Do the malfs happen while there are 8 rounds still in, or when almost empty?

I'm corn-fused.

ALSO, what follower number on the original mags, and what number on the newer one?

K

[Jonas101]

The malfunctions happen when the mag is almost empty.

The gun is being looked at today by a certified Glock Armorer just to see if anything else might be wrong with it. I can tell you that the followers have significant wear on them. The wear patterns on both are deep and obvious. I left it at the range with the tech when I was done shooting yesterday. Anyone have any experience with service at Top Gun Range in Houston?

[Jonas101]

I just got off the phone with the Glock Armorer, Jeff Johnson, at Top Gun Range in Houston. He looked at the magazines, and suggested new followers. Great service from these guys!

Thank you all for the help! Once again, you guys were right on the nose. I'll change the part out, and let you all know when it fixes the problem for everyone's future reference with this issue.

[jakemccoy]

Hi Jonas,

Can you answer a simple question: what number are the followers? Many people have asked you. Are you even reading the replies here?

Regards,
Jake McCoy

[Jonas101]

I sure am! If you read my previous posts, you would find that my pistol is currently in the possession of a Glock Armorer being evaluated. I do not currently have the pistol with me. I figured everyone would put 2 and 2 together in that regards and that's why I didn't state something I felt to be obvious. I apologize.

I am, however, ordering 2 brand new #8 followers on the suggestion of you guys and the Glock Armorer who is currently in possession of my G27.

Thank you everyone for your help in this matter.

Well, I've experienced the same problems with my G27 - especially when using Speer 165gr GDHPs. I changed the magazines that came with the pistol to #8 followers (Glock tech support provided) and also purchased two brand new magazines with #8's already installed. With all the changes, I'm still experiencing issues with feeding.

I have since spoken with Glock tech support (awesome by the way) and am awaiting a new recoil spring and locking block. If this doesn't cure the problem then the gun will be sold. I simply cannot tolerate an unreliable pistol.

Prior to the changing to #8 followers my Glock came with #7s. It wouldn't feed much of anything reliably. After the switch to #8s the Glock would feed Blazer Brass but will not reliably feed my issued Speer GDHPs. I can only hope that by changing the locking block and recoil spring that the pistol will start acting like a Glock. I've never experienced any issues with a Glock before so this is all new to me.

I find it hard to believe that brand new magazines will have bad springs.

[skunkworks]

Went to the range this week with a brand new G27 this week. Used Winchester White Box (FMJ) WWB and Ranger RA40T both 180g. With the WWB had two FTF.

All Mags were brand new.

Will find out what followers later this PM.

[Jonas101]

I have a new mag with a #8 follower that works just fine in my pistol. I think changing the #6's to 8's will fix my issue. I'll keep everyone posted when I receive and install the new ones.

Jonas, the #8 followers supposedly will not work well in magazines that come with #6 followers... at least that's according to www.glockparts.com and he's a GLOCK armorer. You should strongly consider just replacing your #6 magazines with new generation #8 magazines altogether.

[skunkworks]

Looks like both mags I was having problem with both had #6 followers. I had a third #6 mag that was unused. All three purchased last week. Looks like that could be the culprit.

Now to see what the dealer says.

I just had a great experience with GLOCK customer service. I told them I had a feeding issue with my G27 and that I had #6 followers. On their recommendation, GLOCK is sending me (2) #8 followers plus 2 magazine springs. They are also sending me an additional spring for comparison purposes. They recommend taping the spring to a piece of cardboard and comparing it to the springs in the mags I'm using when I clean them. If they are 1 to 1 1/2 coils shorter than the cardboarded spring, I need new ones.

They are also not charging me for any of these items. SWEEEEET!!!!

Interesting, I spoke with INC yesterday and they said you can't just put a #8 in a #6 generation magazine and told me to send all my #6 mags in for service. :dunno:

[40SX]

As I read this thread my Glock 27 sits in the safe for reliability issues, its been in the dark safe now for about two years. Mine has an "F" preface and is somewhat like others in this thread with feeding problems with both WWB and Speer Gold Dots in 165 grain. Evidently some 27s work and some don't. I have many reliable weapons to protect my loved ones and myself, I'm not going to count on a problematic firearm that misfeeds one or two rounds in a hundred. My luck it will be those one or two rounds I need.

Good luck to all with 27 feeding problems.

Wow. I'm pretty suprised to see some of the reliability issues. I agree with anyone, if the gun cant perform 100%, especially for a protection weapon as opposed to a safe queen, then I too would get rid of it. My other 2 previous CCW guns were a Taurus and then a Defender 1911; both could not get there way out of 4 magazines without some kind of issue. Sold them.

The G27 was my first GLOCK, and not my last. It sold me on the reliability and I now trust it. I have had no less than 10 different name brands of ammo thru it from 155 to 180 grain, wolf, CCI brass, CCI alumin, WWB, Hydra shock, etc, etc. and NO issues after 1900 rounds of logged range time. I have had it for 10 months now and love it.

Also on the magazine issue, I have 2 that have Pearce +2 extentions and 2 stock floor plates with zero problems. I also now own 18 (15 round) GLOCK 22 magazines (I bought a 22 after the 27 -I loved it so much I had to buy the big brother to the 27 :) and I use these at the range in the 27 WITH ZERO ISSUES. I love to run the big mags during long range sesions so I dont have to reload every 5 minutes. They work great and I love the interoperability of the 2 weapons' magazine swap.

[cole]

Evidently some 27s work and some don't.

MOST Glock 27s work, a VERY few do not. Pretty much goes for all Glocks, or guns of most all reputable makes. Thinks of the thousands and thousands of them out there an how few "problems" we hear about.

If you have not tried #8 followers that would be the first place to start.

Yes, the ones that do work won't get you killed, the ones that don't, might. Out of the sixty some handguns I own, the Glock 27 is the ONLY unreliable weapon I own. This is the second Glock 27 I have witnessed this problem. I have documented this several times here on GT. These are very bad odds to commit my life to.

BTW, as a response to an email I recieved, I cannot sell this handgun the way it is working and have a clear conscience that if it is needed it will function properly.

Dennis

[Landmonster]

My Glock 27 works 100% fine with the 9 round mags, but seems to jam alot with my G22 15 round mags with #8 followers. Any ideas why?


The simple solution is just to carry the 9 rounder as backup, instead of the 15 rounder... but that is slightly disappointing.

[Jonas101]

As stated before, my G27 has been FLAWLESS up until last weekend when I went to the range and had issues on my 2 stock mags with #6 followers. The FTF's were ONLY on the 8th round on BOTH magazines. The certified Glock Armorer looked at my magazines and said the followers were VERY worn and needed to be replaced. Same thing happened when I spoke with Glock. I have a brand new G27 magazine with a #8 follower that doesn't cause my weapon to FTF.

Please nobody think this is a malfunction of the G27 because it's small. This is a MAGAZINE issue. My G27 shoots like a champ and always has. It has loved every bit of ammo I have fed it. Even the crappy Monarch stuff that Academy practically gives away. I love my G27 and would not get rid of it ever. The beauty of the Glock weapon system is the ease of maintenance and parts availability. Hell, the part that is causing my G27 to FTF costs $3.00!!! Would you really sell your gun if that's all you need to make it work properly again? Really?!?

Once again, my G27 is perfect. The $3.00 part. inside my magazines isn't.

[jmancini]

My G27 has been perfect for almost 10 years now. It came with #5 magazine followers and they worked perfectly. Routine maintenance only and I did finally swap out the recoil spring. Has always eaten everything I've thrown at it.

Recently I added a few new magazines, they had the #8 follower. I began having all kinds of wacky slide lock issues (failing to lock on an empty mag, mags not dropping). It turns out that some of the older 27's need to have the slide stop lever replaced with a newer one to work reliably with the #8 magazines - the newer slide stop has a 1.5mm longer 'tongue' on the inside where it mates with an empty mag. It now works perfectly with both the #8 and #5 magazines.

Just FYI.

One of my pet peeves is Glock changing their magazines and followers at a more pronounced rate than I change my underwear just to get some of their Glocks working proficiently. My series "F" Glock came with #5 followers. In a matter of about three or four years, we now have a completely new magazine shell and we're up to an 8 follower. Some of these mags work in some 27s and others do not. There must be a pretty significant manufacturing variance somewhere in either the mags or the gun.

I can take ANY of my H&Ks, Smith and Wesson semis, Sigs or Springfield stick the mags in their weapons and they function without a problem. Our other three glocks work without any problems. Why not the Glock 27? If a very small degree of difference in a magazine follower is going to make my weapon go or not go, I'd rather use something for carry I have much more confidence in.

With my Glock 27, three different shooters, three types of ammo, WWB, Speer Gold Dots in 165 grain and to a lesser degree Remington Golder Sabres. Magazines with 5, 6 and 7 followers, a new recoil spring assembly sent to me by Fred at Glock after a lengthy phone conversation and a church exorcism. :dunno:

If this didn't happen to me and at the very same time happen to another gentleman at the next shooting position the same day of December 2006 as he shot his Glock 27, I would have thought I had the only fluke Glock. His Glock 27 was his carry weapon with only about six hundred rounds though it before it started to misfeed that day. He also made the comment about loosing trust in something he carried for several month before. This is MORE than a coincidence.

[gtmtnbiker98]

Well, to update my situation, I just received my replacement locking block and recoil spring assembly for my G27 this afternoon. I just finished detailing my pistol and inserting the replacement parts. I compared the two locking blocks (the old and the new) and noticed that the locking block that came with my G27 (KLH prefix, manufactured Sept. 2006) had a #4 locking block. The new locking block is a #6 and just a tad longer than the #4 and that was the only difference I noticed. The recoil spring assembly is the same as the one that I'm replacing.

So now I've replaced the recoil spring assembly, the locking block, and have purchased new magazines and have replaced the original magazines with #8 followers - so hopefully I'll have an error free shooting experience come Sunday when I get the chance to shoot. Wish me luck, because I do not know what else I can do to get this thing to function like the rest of my Glocks.

I'd much rather see them actively designing parts in an attempt to make the pistol more reliable than saying "they should work; they always have".

Don't kid yourself that Sigs, H&Ks, S&Ws and others haven't had any reliability issues, regardless of your personal experience.

But, I do wonder about the relatively rapid changes in followers. Could a feed ramp change, or a change in case support (this being the notorious .40 after all) requiring them to change the followers? The only reason I think of this is because the older 27s with #5 & #6 followers seem to function fine, while newer 27s seem to have needed a follower tweak.

Interesting. Where did you get the information on the newer slide stop lever? And what's the part number stamped on it?

Yes, the ones that do work won't get you killed, the ones that don't, might. Out of the sixty some handguns I own, the Glock 27 is the ONLY unreliable weapon I own. This is the second Glock 27 I have witnessed this problem. I have documented this several times here on GT. These are very bad odds to commit my life to.

BTW, as a response to an email I recieved, I cannot sell this handgun the way it is working and have a clear conscience that if it is needed it will function properly.

With your G27 as the "ONLY unreliable weapon [you] own" you have had INCREDIBLE luck with your 60 SEMI-AUTO handguns. I've not quite enjoyed your perfection minus one success with the semi-auto handguns I've owned over the years. I can say my revolvers have been 100%, and my Glocks have been incredibly reliable semi-autos.

This is far from the first problem Glock I've read about, or S&W, H&K, Sig, and so on. The internet has a way of spreading bad news far and fast, with many of the same people posting problems about the same gun on multiple forums, and even on each forum multiple times. As a percentage, problems are very small, they all are very small.

That said, bottom-line: If you don't trust your gun sell it with full disclosure. As far as your reply not wanting to sell it due to a "clear conscience"; that seems a bit melodramatic. If you tell the buyer it's had issues and they buy it that's on the buyer. Of course, you'd need to adjust the price down accordingly.

I agree with comments here that the frequent changes by Glock in followers is annoying. A gun should work 100% as sold. Glock is famous for it's "upgrades", never recalls.

Today I took my G23 and brand-new G27 to the range. I had a half-dozen G23 mags with #7 followers, and the two G27 mags with #8 followers. None of the G23 mags had much use as I had only ran about 200 rounds through the G23 previously. I ran a total of about 300 rounds between them, probably pretty evenly split. The G23 never skipped a beat, and the G27 ran flawlessly when I was using the G27 mags. As soon as I put a G23 mag in the G27, it jammed every 2-3 rounds, because the angle of the bullet wasn't right. There was just a little too much movement with the G23 mags in the G27. Previously, I had a number of jams with the G23 using Remington 180 grain cheapo ammo. This time all I ran through both guns was Federal 155 grain HST. I was very pleased with the performance of the ammo in both guns; I just wish I hadn't had any problems feeding the G27 with the G23 mag as I wanted to carry a 13 rounder as a backup.

Well, to follow-up with my issues, after replacing the locking block and recoil spring assembly the pistol performed like a Glock should, today. I put 300-rounds through it this afternoon without any issues - hopefully she's fixed.

What I did to correct the issue:

1. Purchased two new magazines
2. Called Glock and requested #8 followers to replace the #7s that came with the pistol
3. Called Glock back and requested new recoil spring assembly and locking block

When I changed to all #8 followers the FTFs seemed to have corrected with Blazer Brass 180gr; however, Speer GDHPs (department issue) would not reliably feed (occasional FTF).

Called Glock back, advised of problem and requested new recoil spring assembly and locking block (DannyR suggested the locking block change - giving proper credit). The recoil spring assembly is the same as the one I replaced; however, the locking block that I replaced was a #4 and the new one is a #6 (slightly longer bearing surface for lockup). I feel that a combination of the #8 followers and the newer (updated) locking block cured the issue.

I'm writing in more detail in an attempt to help those with unreliable G27s.

cole, where did I say that I have 60 semi autos? About half of my collection is comprised of revolvers. Do you like reading more into a statement than what is typed? Concerning the statement melodramatic, go back to your soap operas. This is how I feel about a weapon that is manufactured to save a life, not condemn it with frequent reliability problems. It just shows you have a little less couth than most humans.

Dennis

[Glockdude1]

Which followers are in your mags?

The most current appears to be the #8 follower.

I've read of a lot of issues with other-than-#8 followers.

Try a #5 follower. They work great in my G27.

:winkie:

In a discussion of semi-auto reliability you include 30 revolvers in your 60 gun comparison? My "60 semi-auto" misquote was an intentional misquote because I figured you'd counted a significant number of revolvers in a very impressive collection like that. It of course makes more of a grand statement to say 60 guns than 30 guns, which is often the point.

No one will ever argue that revolvers easily beat ANY semi-auto hands-down in reliability. Now, to say you own 30 semi-auto handguns and your Glock 27 is the only unreliable one is an apple-to-apples statement, and that still makes quite a statement about your probem G27. Your Glock 27 does in fact appear truly problematic.

Still, even with a 30 semi-auto comparison, I've not enjoyed your 100% reliability success minus the one Glock 27, especially if you count my past/current 1911s, particulalry the 1911 compacts.

Soap Operas? Funny that one. Anyway, as for the sale, it's not about couth. You tell a grown adult, "This gun has had reliabiity problems, you still want to buy it" and that grown adult says "Yes", what's the problem? If you are totally 100% honest about the gun, let the buyer make the decision. But, you and I clearly feel differently about this.

Again, adjusting the sale price $50-$100 down is what most folks do not want to do. Most of these problems guns get cycyled through the system OVER AND OVER AGAIN becuase "un-couth" people sell them or trade they without disclosing the problem. So, we often hear about the same gun time and again, with the same owner or the sap that just bought it.

Back on topic, again, both my past/current Glock 27s have been 100% with anything I've fed them regardless of follower. As is my Glock 26.

I am going to respond just this one time because evidently there are other people on this thread that are not having the excellent luck you're having with your Glock 27. I really don't care if it's a revolver or a semi auto, if the problem cannot be rectified quickly and efficiently with one of my carry weapons, it will end-up sitting in my safe next to my Glock 27. Actually I've had more luck with semis than I've had with revolvers. I had a Colt Lawman MK lll that broke a firing pin, an easy fix for Colt, but a bit expensive. I gained all my trust back in that weapon. I have a S&W 686-4 2 1/2 inch revolver that needed the attention of S&W's service department at the tune of about $125, I now have complete faith in that particular weapon. Which brings me back to my unreliable Glock 27 where after more than a few attempts to cure its problem, it's no better today than it was over two years ago. Not a great confidence builder.

You happened to touch on disclosing the problem to a potential buyer, well that's great as long as he does the same, which is beyond my control when he decides to also get rid of my once owned problematic Glock 27. I don't want someone getting killed with a known unreliable weapon I once owned. You also mentioned about weapons cycled over and over again, well this can't happen with mine if I won't sell it.. will it.

Dennis: Sorry about the melodramatic comment. Did not intend offense. We do differ in how we see the sale of a problem gun with FULL disclosure.

I agree with you there cole; I have NEVER found a 1911 function with any "carry reliability" under 3.5 barrel. I think the best size in a 1911 (or the smallest one sould go) is the Combat Commander at 4.5". Beyond that (smaller) a 1911 is a gamble, even though they are still my favorite shooters.

[Jonas101]

For everyone's information...

I received the new magazine springs and #8 followers yesterday. Upon disassembly of my G27 mags, I compared the springs inside to the new springs from Glock. One of the old springs is one coil shorter than the new ones, and the other old spring is 1 1/2 coils shorter. Glock recommends changing springs if yours are compressed by 1 to 1 1/2 coils compared to new ones. These mags are almost 2 years old, and I keep them loaded all the time.

The #8 followers and springs fit perfectly in my mags as well. I'll go to the range this weekend and update everyone on how they feed.

[Jonas101]

The #8 followers and new springs fixed the feeding issue. FYI.

[gtmtnbiker98]

Well, between the #8 followers, new locking block, and/or recoil spring replacement, my Glock seems to be acting like a good Glock should. I just shot 129 165-gr SGDHP rounds again today without a simple stoppage. Since the replaced parts, I've shot 400-rounds and can now "hopefully" assume that it is reliable and suitable for carry.

For those experiencing the 165gr failure to feed issue, replace the followers, locking block and recoil spring assembly and you "should" be good to go. Glock will provide the parts, the did for me!

[tone]

Which ones are you referring to? I'm trying to find some for my 27, but cannot completely identify...

[texLJ]

I'd much rather see them actively designing parts in an attempt to make the pistol more reliable than saying "they should work; they always have".

Don't kid yourself that Sigs, H&Ks, S&Ws and others haven't had any reliability issues, regardless of your personal experience.

But, I do wonder about the relatively rapid changes in followers. Could a feed ramp change, or a change in case support (this being the notorious .40 after all) requiring them to change the followers? The only reason I think of this is because the older 27s with #5 & #6 followers seem to function fine, while newer 27s seem to have needed a follower tweak.

Notice that, through the years, as the followers changed, so did the bodies. Newer ones the front lip of the metal liner goes all the way to the top, not so on earlier ones.

The reason Glock gave me for continually upgrading their followers is to keep pace with changes the ammo manufacturers make in the shape of their bullets, mostly the jacketed hollow point rounds, specifically the "self defense" loads all are coming out with. As the shape and hollow point opening size of the bullet has evolved, so has the shape of the follower that will provide the acceptable feed reliability.

That's what Glock told me, though, so what do I know...

I've upgraded the mags in my 23 (S/N BNM189) and my wife's 27 (S/N BRZ387), both bought in late '95 and early '96, to new ones with #7 followers (sent to me by Glock), and both are performing flawlessly, as they always had before, using Federal HydraShok. I made the upgrade because I intend to switch to Spear Gold Dot 165 gr, which my son uses in his new 23 (last year) which came with the #7 follower equipped magazines. His gun, new last year, has performed without a single malfunction, as have both mine and my wife's, which are now pushing 13 years old. Oh and by the way, the Glock guy told me our old Glocks needed nothing in the way of upgrading to handle current ammo other than the new magazines.

What I expected from Glock, and what I've gotten.

[wheel]

After reading this thread I examined the followers in my own 9mm mags. Two are #6 and one is a 9mm1. None of them have ever malfunctioned, and my G26 is serial BPTxxxx, circa 1996 (?).

What's interesting is that one of the mags with the #6 follower I purchased new (via mail order) about a year ago. So I guess you can't guarantee what you get unless you see it before you buy. There must still be a lot of #6 followers in new mags being sold.

ETA: Wait a minute - I did a quick search and it appears #8 followers are for .40 cal only. It appears #6 followers are the latest version for 9mm. Is that correct?

[cammed3800]

I bought a new 27 mag from gander mountain a couple weeks ago that has a #6 follower. Both the mags that came with the gun are #8.

I'll have to it out and see what happens

[wheel]

Can anyone confirm for me what is the latest follower for 9mm mags? Is it #6 or #8 ?

Thanks.

im in the same boat, brand new 27 both #8 followers, 3 months old and cannot shoot a full mag with ftf issues. it looks like 2 rounds are coming up too fast for the slide to cycle. shall i send it to glock? i thoguth in time the mag spring would weaken and all will be fine. but its been 3.5 months fully loaded all the time. any suggestions, thanks

[G. Glock]

Geez, I've never had functioning problems with ANY of my Glocks, including the three different G27's I've owned (Still have two). I couldn't tell you what number my followers are, that's for sure. Probably couldn't tell you the numbers on any of my magazines' followers, and I have a bunch in almost every caliber. Never had a reason to care. "It ain't been broke, so I ain't tried to fix it."

They've all worked just fine with any magazines I've stuck in them, G27 mags, G23 mags, or even G22 mags.

Sometimes I think there's something wrong with me; I never have these problems I should be having!! ;-) It just ain't fair!

Some info about what ammo you're using, what hold (one hand or two), etc, might help. I cannot make sense of your description of, "2 rounds coming up too fast for the slide...".

hey texlj, thanx for replying, it looks like one round is partially in the ramp and the round under it(in the mag) is pushing its rear upward and the slid is stuck half chambered...that does make sense? the only way to clear it is drop the mag, pull slide back and let the ammos fall. it seems to me that the mag springs might be too strong but ive tried other mags and i run into the same problem after the 4 or 5th round. help ...anyone!!! this is sooooo depressing!

I hear what you say, and can visualize it, but have never had (or seen) it happen. I THINK this would be the result of what I've read about the condition known as "limp wristing", although neither my wife nor I have ever experienced it.

If you can, I would do one of two things. One - have someone else, who is a semi-auto shooter regardless of brand, try the gun. Two - try using a very firm two-handed hold and fire the gun. Failing at these, I'd call Glock and describe the problem to them. They will, I'm sure, recommend that you send the gun and magazines to them. And they're very good. If it comes back from them certified as okay, then I'd know it was me, and something I was doing in firing the gun, or the ammo I was using.

I'm assuming, of course, that you're using factory ammo, and not reloads you or others did. And I mean by others that you can buy reloaded ammo. Neither of these is good. Do not do it. Use only factory loaded NEW ammo.

Don't know if any of this helps or not. I will tell you however, that I am intending to get another G27 in the next few weeks, and I would be AMAZED if, when I do, it would not fire factory fresh ammo flawlessly.

Oh and by the way...all new Glock magazines are very stiff to load. In my personal experience, I've never had a malfunction as a result of this.

[glockfull]

This is my first post and this thread made me want to join Glocktalk.

The expertise and helpful targeting of the potential problem and members participating in helping to solve the problem. Bravo.

Anyway, I have owned a G27 since new in 96' never knew why it wouldn't lock back on pre-ban G22 mags or why it had the failure to feed problems it has. For the longest time I thought I was limp-wristing.

I have been into long guns for a while and am getting back to CCW (and my handguns).

I am determined to keep my G27 as my main carry but need to gain my confidence back in the gun. My only other option is to get and HK (:wow:) and give that a shot (no pun intended) but it is an expensive route if I go there.

My hope was to keep the G27 and get a G23 for mag/ammo compatibility but if I have to go to another platform for reliability it will take me a while to change over.

I have retired my two origional mags with #4 followers and all of the G23 & G22 mag I have right now are new w/#8 followers. I plan on getting a new locking block and hope that solves my problems.

Last time I was at the range I still had one mysterious situation where I was through half of a magazine and the slide just stayed open (not locked back but just stayed open). I had to manually push the slide and it pushed the next round into the chamber. I was being very conscious about not limp wristing but this could be a slim possibility. I have only put 900 rounds through the gun since new (all factory new Speer Gold Dots, Federal, etc.).

Another option to stay in the Glock family and have better reliabilty (if I can't work the bugs out on my G27) is to get a G19 or G26. The only problem is that I have lots of .40 cal stocked up and lots of .40 Glock mags.

Thanks,

Glockfull

[happy seal]

I just got off the phone with the Glock Armorer, Jeff Johnson, at Top Gun Range in Houston. He looked at the magazines, and suggested new followers. Great service from these guys!

Thank you all for the help! Once again, you guys were right on the nose. I'll change the part out, and let you all know when it fixes the problem for everyone's future reference with this issue.

Isn't that exactly what half of these guys were trying to tell you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!:faint::shocked:
