Glock Issues Recall for Gen4 Recoil Springs

I don’t own a Glock, but I have heard the new Gen4 is glitchy.

GLOCK Inc. announces that it is voluntarily exchanging the recoil spring assembly (RSA) on its new Gen4 pistols shipped since August, 2009, to ensure each pistol’s performance meets the company’s demanding standards.  With several variations of the RSA in the market today, GLOCK’s goal with this voluntary exchange is to standardize the RSA to gain the best possible performance in each pistol.

GLOCK’s product development team has modified various elements of the RSA.  The new RSA compensates for all design modifications made to the Gen4 and allows the pistols to function up to GLOCK’s rigid quality standards and reliability goals.

Consumers should note that Gen4 G26 and G27 models will not require a modified recoil spring.

The replacement of the Gen4 pistol RSA can be performed as part of the regular field-strip process; consumers do not need to take the Gen4 pistol to an armorer.

  1. I have never needed any replacement parts on my Sig p220 or 226 and they are nearing the decade mark with a few thousand rounds through each. You Block fans can keep this airsoft feeling hunk of junk.

  2. I carry my P229 but the 2 Glocks are always in the go bag. Going to go ahead and replace the spring.

  3. So, there's a non-specific problem with the guns thats being fixed by a replacement part that I don't recall anyone saying they needed, and most of the people who are getting it don't have the foggiest idea why…I do believe I'll go ahead and save a few bucks to puck up a Gen3 17 for my service handgun.

  4. LOL. So Glock is telling people to get their GEN 4's RSA replaced, but not telling them why? Nice. Sounds like something they would do.

  5. I know why their replacing them though…..

  6. I use a Beretta M-92FS Police Special for work never had a jam or broken part with it when having proper ammo. I just cant trust plastic guns.

  7. Now all the Glock-haters will have a field-day jeering at the "plastic" pistol…..

  8. Just bought me a Gen3 RTF. Couldn't be happier…I hope this isn't the beginning of the end for Glock.

  9. Ah, nuts. Don't care for them new fangled pistols. Keepin' my old reliable six shooter, never let me down.

  10. I own a Gen3 27 with the double (captive) recoil spring and have had no problems. Sometimes these recalls can be a little confusing, so can I assume my current configuration is A-OK?

  11. The issue with the new RSA is the spring will not push back light ammo. If you are shooting anything over 115 grain in a gen 4 Glock, you will probably not see any malfunctions. With the replacement RSA, they are sending out you can shoot light loads and not worry about a malfunction. The purpose of the heavier RSA in the gen 4 was not to shoot target rounds or super light 115 grains, it was made for a combat, hot round. You can shoot 147 grain all day long in the gen 4 and not worry about shit. I dont have to worry about this issue because I carry a gen 3 :p

  12. No problem for me, I have one and mine is perfect. From day one i orderd a solid tungsten guide rod and sweet spring from Glockmeister. Any pistol i have gotten in the past and future always gets the personal pref add ons. No matter the brand or size from my BUG to my main weapon. Those range generals i see are posting their cr@p what a joke.

  13. Truly is. My brother has a Sig, manufactured in Germany about 10 years ago. Outstanding piece of kit. Didn't have to break it it or any of that crap…the thing just runs. Wonderful trigger compared to our Glocks.

  14. The problem is with 115 grain loads also. Trying to fix an undersprung .40 with a new RSA that doesn't work is a bad idea. Then they turn around and put the same RSA in the 9mm guns. WTH! Glock needs to fix those newer GEN 3's effected by their corner cutting as well. Glock never ceases to amaze me.

  15. Extraction and ejection are directly related to the recoils springs. If the spring resists too much slide velocity is lowered to the point that the empty case is not ejected with enough force to overcome the grip of the extractor, thus hang ups and cases ejected on less desirable trajectories.

    It's not the first time that a 'one-size-fits-all' approach to lowering manufacturing costs has not worked out… However, until someone tries a new way of doing things, how can you know if it works? Though, this sort of thing should have shown up in testing before thrown into the product.

  16. @ Mike Birchfield

    The Army's poor maintenance of weapons is to blame not the M-9 itself. The USMC had them for years and not as many breakages reported needs more training that's all and more armorers maintenance. Ive out shot Glocks and SiGs all the time with my M-92FS.

  17. This may sound dumb, but how do you know if ur glock is a Gen4 or not???
    Is this recall specific to only Gen4's?
    Thanks and forgive my ignorance

  18. Yup, the M9 is an old weapon that the Army fires outrageous amounts of ammo through every year. They get beat up by their owners and often are not cleaned or have the magazines cycled through enough. Although I've fired the M9 many times and never had any problems, I've always thought that big Army should have bought Glocks or Sigs, but I'm sure a gun without a safety would never float.

  19. I believe it's specific to Gen4 pistols. I called them and read off serial #s and both mine (a 30 and a 17C) were good (no RSA replacement required).

  20. nothing like those 2 Sig recalls of the past 2 months, first on the P238, then the 1911-22 – no Sig doesn't have any recalls.

  21. I've got a glock gen 4 .40 cal. with over 1200 rounds put through it. STILL no problems……

  22. I carried a gen 2 M17 for 10 years. I stopped counting rounds fired after I reached 22,000. I gave the newer g3 guns to the young guys, having all the faith in the plastic M17. We had one gun with a double charge that kicked out the magazine, split the frame, but kept on shooting. My M22 G4 has only had 75 rounds through it in an IDPA match. I hind sight, I'd rather have a M17. Early Glock M17,19 and 21 gave serious problems. After the retro-fits they were just fine. Just looking at the G4 spring, all I saw was potential for trouble. It became too complex.

  23. This is a command failure. Just like with the M16, the whole unit didn't take care of their rifles, trucks, power equipment, or themselves. When commanders don't demand more from their sergeants and troopers the whole system collapses.

  24. I think getting a M17 for duty is a good idea. I carried a M17 for about 10 years. I stopped counting shots fired after about 22,000 rounds. I retired nearly 10 years ago. I bought a M22 Gen 4 and a M27. Now I wish I had bought 9mm models. I liked how well the 9mm shot and I know I could outshoot myself had I used a 9mm instgead of a .40.

  25. I recently bought a gen4 22 Glock. Changed out the barrel with the 9mm conversion and the glock experienced failure to extract with cheap 115 gr 9mm rounds. Problem was caused by limp wristing the gun. As soon as I tighted up my grip, the problem went away. The gun still spits shells at you however.

  26. I have a Glock Gen4 Model 22. I have over 12,000 rounds and noticed a problem this past Friday. While firing the gun, the spring came through the hole in the slide about 1''. It prevented the gun from firing. I also had the same problem when I racked the slide after cleaning. I brought the gun in this morning and was told there was a recall on the spring. They gave me the 1-800 number to call for replacement. The rep at glock said that the model and serial numer of my early gen4 qualified for the spring replacement. I explained what happened and he stated that the new spring was redesigned with a spacer on the front of the spring that would prevent that from happening in the future. He took my information and stated that a replacement is on the way.

  27. I recently bought 2 Glock 17s and a 19. The Gen 4 does not like 115 grain ammo and continuously double feeds (on only one 17 and the 19). My regular duty ammo showed no problems. My new spring is coming and after speaking with my team's armorer, this should remedy the problem.

    And for you Sig lovers out there, I've been shooting Sigs for years, but the Glock system allows me to put many more rounds down range faster and more accurate. Besides, I love using interchangeable mags for my undercover, off-duty, and duty weapon.

  28. I have a gen3 19rtf and a gen4 27 among many other pistols, as of now the gen4 Glock 27 is my go to gun when I want an auto loader. I've put several thousand rds through it with zero malfunctions, I love the thing

  29. I also have a Gen 4 .40cal. and I've put about a 1000 rounds through mine and haven't had a single problem. I've been using mostly 180 grain and some 165 grain.

  30. Just got mine. A lot less side to side play in the spring due to a better designed spring guide. We will have to see how it performs. Speaks highly of a company to do such a selfless thing. GLOCK LOVE!

    i have two new glocks, the g22 gen4 and g23 gen4 and have had no problems with either pistol with the original dual springs that came with the guns, and my g23 gen4 was used in defense of my person twice and did not fail me. but if the new springs lock up better in the muzzle end i am all for it and welcome it.
    i don't look at the recoil spring on gen4 pistols as a recall but an upgrade in my opinion, the muzzle end in the recoil spring assembly is to help the spring lock up better thats it and not a failure of original spring (dual)

  32. well i bought a gen 4 glock 17 nothing but stove pipe fte…. mine has the new recoil spring now they are replacing the ejector #336 with the #30274 whats next ? no one takes pride in what they sale anymore. what happened to the good old days when eveything was hand made. well they still do that like wilson combat but its gonna cost. the other day they had a recall on my wifes shoes. man take a little pride in what you do glock
    im probably going to sale my glock to heck with mailing it in and waiting weeks or months to get my gun back just for another recall. when buying guns its hit or miss. peaple say oh my sig is better what ever i have seen sigs go bad to like when they released theyr new 1911s so what ever your fooling yourself if you think you cant buy a bad gun from your favorite manufacturer

  33. ya but ive never had an glock be so large that most people can fit it in there hand without adjustment plus a glock dosent look and feel like a blowing ball.

  34. Just fired my G19 with replacement rsa installed.Unfortunately I changed it out and returned the original 2 weeks ago. Big mistake, I should have kept it. I never had any problems myself, my wife had ftf due to lim wrist. The problem I have now is brass in the face about 20% of the time. Before the replacement I could eject brass into my catcher like clockwork now I can catch them with my teeth. Keep your original rsa until your satisfied.

  35. I have had 2 kabooms on my Gen 4 .40 cal. and have not even shot 50 rounds through it . Glock has no answer for the problems even after it was "UPDATED" by them , they want say it is a recall , just "UPDATE"……

  36. Just changed my spring in my gen 4 9mm. Had no ftfire before but glock suggested I change to the new one. Big mistake had 3 jams out of 110 rounds 100win. White box 10 hornady critic def loads all jams were win. Called glock they said try different ammo. I told them no problems before changing spring. They said try them again that I may have gotten a few bad rounds in that cheap ammo. Going to try again. Glock said call back if trouble continues and we would go from there.

  37. glock only to 6 months to listen and fix the gen4 recoil spring problems, and when they fixed it they did it for free with an express mail replacemnt so what more can you ask for?
    the gen4 recoil springs only needed a end cap, and the 9mm springs only needed to be reduced a small bit in power and bam back on top again.
    i own 3 gen4's in three caliburs with no issues holla.
