The Glock RSA Exchange Program

The Glock RSA Exchange Program
The Glock RSA Exchange Program

Recently, I had learned about the Glock RSA Exchange program. I was surprised to hear that my local range was unaware of the program. That led me to think that others have also not heard of the program.

GLOCK Inc. is voluntarily exchanging the recoil spring assembly (RSA) on its new Gen4 pistols (with the exception of G26 and G27 models). GLOCK has developed a new design to the recoil spring assemblies on its Gen4 pistols to replace several variations that are functioning in the market today.

As part of the company’s commitment to perfection, Glock is voluntarily exchanging the existing RSA in order to ensure their products perform up to GLOCK’s stringent standards.

GLOCK is replacing the RSA in all Gen4s sold before July 22, 2011, at no cost to you.

Here is what you need to do:

  1. Call 1-877-745-8523 and you will speak to a very nice person. Have the serial number and model number of yourGEN4 Glock handy to request your modified RSA.
  2. GLOCK will verify your serial number and collect shipping information.
  3. Within 30 days (mine arrived within a week), GLOCK will send you a replacement RSA along with a pre-addressed envelope to mail your old spring back to Glock.
  4. When you receive the replacement RSA, field strip your GLOCK per the instructions found in your ‘Instructions for Use’ manual that came with your pistol and replace the old RSA with the new one
  5. Place the old RSA in the supplied shipping container and give to the United States Postal Service (USPS)

Thank you Daryl for that RSA info. It’s kind of sad that Glock is not contacting those who have purchased before the above said date to make them aware of this exchange program. Once again thank you. 


I called and did the exchange, have not received the new unit yet, however on the phone the GLOCK representative asked me if my pistol was for personal use or duty use. I don’t want to jump to conclusions, but this may be evidence that, with these new RSAs, GLOCK is making two models, one for the civilian shooter who may shoot any type of ammo and one for duty use that may be yet another stiff spring designed for high pressure combat loads. If this is the case, it seems counter-intuitive to their plan of standardizing the RSA.

It may have just been arbitrary data collecting for their statistics for use in marketing, though.

I do love my fourth gen GLOCK pistol, the ergonomic changes and enlarged mag release are great features and I believe it makes them superior handling pistols compared to the third gens, but I kind of do wish they had left the RSA alone. The ergonomic changes with the old gen three RSA would have been the most ideal setup, so as it stands you have to choose if you want the crappier ergo frame with the time proven RSA or the better ergo frame with the new double spring system, maybe gen five will give us the best of both worlds, but I have a feeling all future gens are going to feature the double spring system and that it will, in time, become the GLOCK standard.


Glock is asking if it is for duty, specifically for law enforcement, so they can put the request to the front of the line.

It seems that if the old version RSA is working properly, one would not send it back until enough rounds have been fired using the new RSA, to be sure it is functioning properly. That leads to the next question – what happens if somebody does not return the old RSA and just holds it as a spare? I assume Glock is scrapping them. I’m not recommending it and do not plan to cheat the system, but I wondered what Glock would do, perhaps if you have a future warraty claim associated with that serial number?
