Recoil spring for my "G22 9mm"? :)

Very interesting. I'm not really sure. The .40 spring may be stiffer but I don't know. The only thing I can suggest is getting on a Glock parts site and see if the springs for both guns are listed under the same part #.

Just got the below items for my G22 Gen4. Can I use the stock recoil spring with no problems or do I need a G17 spring?

Yes, its a 9mm conversion barrel.

I have a Gen 3 G35 which I bought a LWD 9mm conversion barrel and I use the factory recoil spring. I think they say on Lone Wolfs web site it tells you that you might have to change the recoil spring, check there first.

I'm sort of confused because on some web sites they show the exact same part number for the Gen4 G17 and G22 spring while other ones have different ones listed. Guess I will just try it and see how it works.

I recently got a KKM conversion barrel and 9mm mag for my G22 gen4. I have never had any failures with .40cal but had lots of eject and feed issues. Part of it was probably the crappy 115gr ammo at the range, but I think there is another issue. While many claim you don't need to change the recoil spring I think you do in a gen4 gun. Glock seems to think so too. I just spoke with tech support and they told me the g17 spring and the g22 springs are different. The G22 is part number FP07577 while the G17 is FP08284. I think the G22 spring is stiffer and the light 9mm ammo does not have enough energy to fully work the slide with the stiffer spring.

That makes sense. I was just reading today that when the gen4 17's first came out there were problems with the recoil spring being too stiff and they had to make a change.

No, you don't need a different spring. For any non ported barrel, which you have, the stock spring will work just fine. Regardless of any conversions. This is from my own experience

Well I am happy that is YOUR experience, but mine is different and Glock says a different spring is needed.

My experience is with a gen 3 g22. The spring is 17 pounds for both a 9mm g17 and 40 g22. So for a gen 4 your results may obviously vary

You are correct, same spring for the gen3, but they are different between models in the gen4.

Since we're on the subject of recoil springs, how often are you guys changing them out? I got 1600 rounds out of mine before my g22 started failure to feed problems and kicking spent brass backwards in my face. About 1 round per mag. I'm using ismi springs on a steel rod. Anyone else having this problem? I was told those springs should last 5000 rounds. Not just 1600.

An interesting question. Just today someone mentioned to me that on a Kimber 1911 it is suggested to change the spring every 1300-1600 rounds.

Definitely seems to be the case. My spring was a sponge. From now on I'll just change it every 1300 to be safe and sound

Is it a gen 4? Google glock brass to face. And then call glock and have them send you a new recoil spring.

It's a gen 3 I bought new last July. Tried a gen 4 my friend has and I liked the 3 better. I ditched the stock rod and spring after the first 100 rounds for a steal rod and aftermarket ismi spring. When I installed the new spring a few weeks ago I could immediately tell a huge difference when racking the slide. Didn't feel like a sponge anymore. Haven't had the time or ammo to get to the range yet but I think the 40sw just beats the [email protected] out of springs in general. It may be safe to say that changing a 6$ part every 1300 to 1500 rounds is cheap insurance.

Well I got a G17 spring and tried it today with the 9mm KKM conversion barrel and it worked great. Put 50 rounds of 115 grain 9mm rounds down the barrel and not a single failure of any type.

Great. I'm glad you got it sorted out. Thanks for the update Ive been thinking about looking into the 9mm conversion myself.
Most of my semi autos are in .40 and I don't own a 9mm at this time. With the ammo situation these days it's probably wise to as flexible as possible.

That's exactly the difference..! The early gen. 4,s had the double recoil spring like in the sub. compacts and then , went back to the single spring up-grade so's two No.s but you want the single spring G-17..!

kirbinster , way to go Bra..!

I don't see the need to change the sprang every 1300 rounds or so.!
Actually , I would not change anything until issues become "chronic".
Some springs last indefinably , 25,000 rds. and beyond. I won't do anything until a problem presents itself . I would however have a nice collect of complete replacements for all things prone to wear and tear.!

Sound advice. I recently ordered replacement springs for all my Glocks. May never need them but if I do they are ready.
