Bump. Anybody?

 

I've NEVER changed one in several .40S&Ws, three .45GAPs, a 32G3, and a 31G4, and I've never seen striker-drag marks in any of my guns with any of my HOT reloads.

I recall vaguely that the first 20SF I bought a couple years ago had a higher-rate GlockMeister spring.

A 20lb. spring makes sense to me.

 

I run my Glock-29 using the Wolff 21 lb non-captive recoil system and springs.

What about the striker spring...try changing it out!

 

Your cases are fine. It does not look like a primer smear. However, the CorBon loads seem a bit warm. When the striker mark starts to disappear on the fired cases (like CorBon), you have a pretty warm load. You can also check to see if the cases will go in and out of the chamber with just your fingers. Years ago I had signs like that shooting 9.3gr. Of Power Pistol with a 125gr. GD. After a while it sheared the lug off of the bottom of the barrel. I was lucky. Your striker mark do not look as defined as mine are, but it could be the primer or the tip of your striker. If your fired cases go in and out of the chamber easily, you should be ok pressure wise. Try a new spring or a stiffer one. One problem with a stiffer spring is that it changes the recoil feel in you hand.

 

Thanks for the replies fella's.

Still opt'ing for the 20lb spring. We'll see where that gets me when I get there...

 

Can anyone point me to a list of the stock spring rates for Glocks, professor google isn't helping much

http://gunsprings.com has the factory spring weights for all gen3 glocks. not sure if it mentions gen4s.

 

I just tried a ISMI 20lb spring in my gen4 compact. I used an adapter and a stock gen3 polymer guide rod so it would fit a gen4. Function was fine using lower powered reloads. To me it seems like the 20lb single spring is weaker than the stock 18lb dual RSA.:dunno:

 

Just a follow up on my above post on the ISMI 20lb spring. I did a little research and found that these springs may or may not need trimming. I got to thinking that the adapter that allows a gen3 spring to be used in a gen4 gun may cause the spring to stack or fully compress before the slide reaches the frame. This turned out to be the case in my gun. If the spring stacks when firing hot loads the frame no longer absorbs the recoil. The impact is only on the barrel lug and the bushing(front of slide). From now on I'll make a point to sure the slide has the full rearward movement whenever I install another recoil spring. I only fired a magazine full of soft reloads with the spring so it does look like any damage has been done.

Thanks, you are right on the money.

Funny info, the full sized Glocks get a 17 lb spring which includes calibers up to 10mm.

The compact series of pistols that go up to .357 Sig come stock with an 18 lb spring.

You are welcome. Slide weight also factors in on spring weight.

 

I replaced the factory spring in my Glock 32 with a 20lb spring, steel rod, and talon rubber grips. Made all the difference in the world, recoil is nothing like it was so now I can easily get off good consistent shots on target again and again.

 

Why does Wolff want you to replace the striker spring if you use their RSA springs?
From their site in the above link:
"Due to the design of the Glock pistol, all Glock recoil springs now include a factory strength replacement striker spring."
For purposes of tuning a slide, I don't see the correlation. I've changed striker springs tuning triggers but not recoil. Am I missing something?
