View Full Version : Gen 4 G26 RSA Issues

Why is it that my Gen 4 G26 RSA occassionally pops out of its seat to the point that I can't get the slide off? It is normal for the RSA to become unseated to a certain degree; however, mine comes out completely on occassion and gets stuck in the serial number cut out.

This is happenning when I go to field strip the gun after I am simply dry firing without a magazine in the gun and obviously no ammo in the chamber. I have a Gen 3 G26 and G27 and they have never exhibited this issue.

In the meantime, I ordered and recieved a new spring (older version) from Lone Wolf and it also occassionally pops out of its seat to the point that I can't get the slide off.

Any ideas as to what could be the cause of the spring popping completely out of the seat and getting stuck in serial number cut out? In the meantime, I am going back to work on getting the slide off. I am having more difficulty doing so this time the the previous times.

Well that sux....

I'll have to see what's up with mine when it gets here. I've got another RSA in my kit box from a Gen3 G26 if that's the case. Will most likely score a Wolff steel rod for it if I start seeing issues come up.

Thanks. By the way, it does have 210 rounds through it and it runs perfect. Also, I am absolutely positive that I properly seated the RSA before the putting the slide back on (unlike my previous thread where I started to have doubts, but now believe that I properly seated it that time as well). I am not new to Glocks, and am in the habit of properly seating the RSA.
I did get the slide off by re-seating the RSA (not an easy task).

Calling DannyR, please.

Okay, this is still bugging the crap out of me. Took some caliper measurments. I measured the RSA hole on the muzzle end of the slide, after safely field stripping my Gen 3 and Gen 4 subcompacts. There are acutally two dimensions there. One is on the inside of the hole, and all 3 subcompacts were close from about .512 to .515.

Measuring from outside of the front of slide, the hole is .435 on the Gen 3 26 and 27. However, on the Gen 4 26, the dimension is .450. I wonder if this difference of .015 could be causing the occassional issue with the RSA and the slide not coming off.

It would be greatly appreciated if someone with a Gen 4 26 or 27 would make this measurement and post it. Of course, safely field strip the pistol before attempting to measure. I would like to see if mine is within spec.

UPDATE: My co-worker brought his new Gen 4 G26 in to work today, and after field stripping the gun, I measured the RSA hole on the muzzle end of the slide. The measurement was just like mine, .450. I was pleased. There appears to be no issue regarding the measurement being larger than on my Gen 3's. The inside measurement was the same as the others.

Have had a similar issue with my 27 g4. I have chalked it up to not properly reassembling. Every time the issue has come up I simply disassemble and reassemble and it goes away. If the measurements are different from generation to generation that would seem to point to Glock feeling a need to compensate for something or fix a different issue.

I've noticed that the metal disc that is the base of the guide rod can warp somewhat, it'll look crooked from the side. Perhaps the disc on that RSA is warped to the point that its overall length is shorter than normal, causing it to drop out of the barrel lug. :dunno:

I might try contacting Glock. It probably is not the first time they have seen this and know the solution. And if it is the first time, I'd bet they would want to know.

I doubt this makes you feel any better, but I remember this happening a few times with my GEN3 G26. It was the only Glock I ever had occasional issues reassembling before the GEN4's came out. Did they actually alter the design of the RSA on the subcompacts for GEN4? (it was already dual spring, so I'm wondering what else they did)

Yes, it's not just for Gen4, it's for all sub-compacts. The G26/27 version is marked either 0-8 or 0-8-1 on the base and the G29/30 is marked 0-9 on the base.

Thanks for the responses. I have asked Glock to send me a new recoil spring with regard to another issue discussed in another thread I recently started: http://www.glocktalk.com/forums/showthread.php?t=1419549.
I am waiting on the new RSA from Glock; however, the new RSA I ordered and received from Lone Wolf is the old style Glock RSA, and it goes into battery everytime, no matter how much I ride the slide.

What spring do you have? If it has the 0-8, there can be issues with the GEN 4 noses. That is why they went to the 0-8-1. The original springs(GEN3) are also fine to use.

I've owned Glock's for over 20yrs, and the sub-compacts are different in that you really have to make sure you've got the RGR positioned correctly, and seated completely on reassembly. Never owned another model Glock that was this "picky" about it being in there perfectly. Just my experience. My 26 is a (2012 build) 3rd gen FWIW.

Good news. Got the Glock 0-8 RSA, and tried it today. Works great. No more issues with the RSA. Put 100 rounds of WWB and 10 rounds of Gold Dot +p through it today. It now has a total of 320 flawless rounds.:supergrin:

RedState,

I have a G27 Gen 4 with very similar problems as you are describing. This pistol was purchased about a week ago and I have included photos of the damage done by the RSA and have returned the pistol to Glock for evaluation.

I have been told many times that it's NORMAL for the spring to come out of the the assembly notch when disassembling the gun.

Further, I would never reassemble the gun without returning the spring assembly to it's proper position.

You can take a look at this and I'm sure you will find it interesting.

With the new spring, the RSA still comes unseated to a certain degree, like normal; however, it no longer ever comes completely unseated, as described in my earlier posts, since using the new RSA. If you haven't already done so, you may want to check out this related thread: http://www.glocktalk.com/forums/show....php?t=1419549

Good luck JohnnieBush.

This may have some bearing. I posted this on another Glock forum website.

"If you look at your recoil spring assembly on your 27, you will notice that it is bowed (not perfectly straight). If you place the bow of the spring facing downward toward the frame, you may experience problems with the field stripping. If you place the spring in any other way that is to say bow up or sideways you'll be fine. Before I figured this out I would occasionally have a hard time with field stripping. So much so that I gouged the inside of the frame of my 26. I noticed when cleaning my guns with a friend who also owns a 26, that his frame was gouged in much the same way. He didn't notice the gouges until I mentioned them.

When the bow is toward the frame the rear contact point of the RSA is tilted back toward the slide lock bar so when you pull down on the slide lock you inadvertently pull the RSA from the barrel. I have muscled the slide off in this situation and caused the frame gouging. The better way is to push down on the front of the exposed RSA and re seat the rear portion onto the barrel."

You are probably aware that their are some dimensional difference in the slides length between the two generations, according to Glock's website.

What is meant by bow of the spring? Its a captured spring so I'm confused here. Thanks.

Lay your captured spring on the table and roll it around. You will notice that it is not perfectly straight, but slightly bowed.

I'm now authorized to "post", so I like to include this information on my new Glock g27 Gen 4 on this forum. My problem seem to have much in common with what RedState is describing.

What I did, - was to ask members to let me know if they had a perfectly working G27 whose RSA (Return Spring Assembly) WASN'T tearing the guts out of their gun. And, yes, I now know that it's normal for the spring to come out of it's normally retained position. (Just put it back in place when you reassemble the pistol.)

----------------------------------------

I just purchased a new Glock G27 (Gen4) on Sunday, October 7th. (My first Glock ever) Even when cycling the action by hand and disassembling the pistol, the spring was becoming jammed between the barrel and the frame and was almost impossible to disassemble. When I was able to disassemble the pistol, I was scratching the heck out of the interior of the frame. This problem made me positively sick on a brand new gun!

I wrote to Glock describing the problem, and they replied!

"It is normal for the recoil spring to drop out of the half circle notch. It should be placed in that notch prior to reassembly."

Hmmmm . . . doesn't seem normal to me, but then again they are the experts on Glocks!

I went out yesterday and put 50 rounds through the pistol to make sure that everything was normal when firing it. When I got home and was able to disassemble the pistol, my brand new gun didn't look pretty. The polycarbonate frame was badly scarred and I am sure that the damage and self-destruction will only continue if I keep firing the gun. I simply don't like to see a brand new gun being destroyed right before my very eyes.

I own a lot of handguns, and this NEW Glock 27 Gen 4, which is three days old, is more damaged and scratched than any other gun that I own! And, some of them are 50 years old.

I took a few pictures as best I could and will take any suggestions on how to remedy the situation!

----------------------------------

I wanted to provide this forum with an update on my progress on my problem. I shipped my Glock G27 off to the factory this afternoon via FedEx Overnight at a cost of $64.47 with Insurance. I paid $549.99 for the gun plus $32.99 Sales Tax plus $2.00 for the Background Check plus a $3.00 Gun Tax. With the return shipping, my total cost is now up to $652.45 for my first foray into the Glock Community. Thatís a lot to pay for a gun that cost less than $100 to manufacturer. Yeah, I know itís hard to believe. Everyone should start by reading the book Glock: The Rise of Americaís Gun! I think that most people that are reading this forum would really enjoy it.


It's hard for me to believe that ANY manufacturer, even Glock, or their professional representative would SUGGEST that itís NORMAL for a recoil spring to jump out itís assigned position and gouge (metal on plastic) the polycarbonate frame of a gun every time itís fired or cycled by hand! John Browning would be turning over in his grave to hear such a absurd story or his ghost would be wailing in extreme pain!

I'll keep people posted of the outcome to my G27 problem.

I am very sorry to read about your dilemma. I took a look at you photos and that's about how the inside of my 26's frame appears. When you field strip your 27, is it hard to take down? If that is the case, then it is your field stripping that is doing the damage and not the actual shooting. Maybe your RSA is so warped that it is disengaging and causing the damage when firing. Hopefully Glock replaces your frame and RSA. You should have been sent a prepaid shipping label from Glock.

Sorry to read about and see your issue. My "range" G26 has more rounds through it than the other G26 (I'd guess maybe 3-4000 but just a guess. I can't balance my checkbook let alone manipulate a spreadsheet to keep accurate track of rounds.) and it has no signs of that gouging at all. I am no expert but that just does not look right to me.

Epilogue Ė A Happy Ending

I want to update everyone reading this forum on the outcome to my problem with my G27 Gen 4 Glock. After shipping the pistol off to Glock, which I wasnít really authorized to do, - I had simply informed them that they were getting the pistol back and I asked them to evaluate the problem that I was having!


I shipped it FedEx overnight and had record of the receipt of the pistol at the Glock factory. Quite a while went by and on Day 29 I received a call from Lee at the Glock factory to discuss the problem. I asked him replace the damaged frame with a new frame, which I didnít feel could be repaired to like new condition. With a little reluctance, I was told that he had to talk with his supervisor. The new frame was APPROVED!


I then discussed my cost of sending my new G27 back for repair. He told me that Glock would NOT pay for any of shipping costs to return my new pistol to the factory. But, he did offer to replace my sights with the Glock Night Sights to at least partially compensate me. So, thatís the story and we parted as friends, - no complaints about Lee.


Yesterday was my Glockís 36 Day Odyssey away from home, - a FedEx Truck arrived with the little box to sign for. What a happy looking little gun. I instantly took it apart to examine the new frame and viewed what looked like the brand new pistol that I had purchased the first week in October. Their packing list was straight forward, - INSPECTED, REPLACED FRAME, MEETS FACTORY SPECS, TESTED OK.


Now to the fun part! Lock myself in a dark room and look at the new Night Sights! (Better than telling time with a new Rolex) They look really nice to me!


Now to the real fun, - add some bullets and start shooting! I shot a box of 158 Gr. Federal Copper Jacket Solids without any malfunction in any way. Then I tried 25 of my own reloads, knowing full well that reloading is NOT APPROVED by Glock. I had spent an inordinate amount of time making sure that my 135 Grain JHP Nosler looked like factory ammo. I even went so far as taking each individual cartridge and dropping it in the chamber of my removed barrel. After hearing the happy little thunk of the each cartridge bottoming out and then effortless falling out of what appears as a slightly oversized chamber, I loaded of up the clips and started firing. Again, no surprises of any sort. The gun fired flawlessly every time and is deadly (Scary) accurate at 25 yards!


I had noticed, upon inspecting the pistol, that there was little or no lubricant showing on the factory returned pistol. Yes, I know that this is NORMAL. On page 26 of my Glock manual, under the section on Cleaning the Field Stripped Pistol, there is a note under the SLIDE stating that the copper colored lubricant found on portions of the slide of a brand new GLOCK pistol should not be removed, as it will help in the long-term lubrication of the slide. Well, I didnít find any of this copper based colloidal lubricate on my slide, so I added an extremely light coating of Nuclear Never Seize 2000, which is an anti-galling copper based lubricant to the slide rail. Now the gun looks like a brand NEW gun from the factory again!

Glock getís Four and a Half Stars out of a possible Five Stars, - which is an outstanding GRADE! Had I received a cash reimbursement for my return shipping cost of the new gun, I would have chosen to award them the full 5th STAR.

Regardless, I am 100% satisfied with the gun at this time.

Glad everything worked out all right for you, John. One suggestion: Remove the anti-seize compound from, both, your slide rails (Where it should NOT be.) and from the slide's reset cam. (Where it no longer needs to be.)

Further Update, - Spent yesterday afternoon shooting the newly repaired G27 Glock and have managed to reach my 200 round threshold. Yes, I know this gun is still a babe in the woods! Although I was told that the gouging was once normal, the new NORMAL leaves the frame unscathed in any way, what a pleasant surprise.

I was so excited after returning home that, I ignored my better judgment and cleaned the little baby. I probably used some unauthorized solvent (like Hoppeís #9) and some Rem Oil for lubrication, but the pistol hasnít dissolved yet!. A little bit baby Rem oil goes a long way.

Iíve attached a couple of photos to document the lack of abuse on the new frame. I wish all stories had a happened ending.

Good deal

There is only two ways to get the gouging

1- Most common, someone maybe a person looking to buy the gun not necessarily you didn't put the spring back in the ASSEMBLY notch and replaced the slide back onto the frame- pushing the spring back into that ASSEMBLY notch must be done every time.

2- A RSA happened to become badly out of spec and caused it- rare but not impossible.

BTW the spring will move out of the half moon ASSEMBLY notch and fall down to operating position, that is normal. There's and assembly position and an operating position.

If you study the way a Glock works there is no way the RSA will stay in contact with the barrel and still work. When you assemble the gun the spring falls down and the rear of the spring rests against the polymer frame (just above the slide lock spring). When you remove the slide the barrel notch catches the top of the spring on the way off and brings the spring with it.

Glad Glock got you cleared up. I have had several Sub-compact Glocks and they are in my opinion the perfect size.
