Recoil spring
New member
I have a Gen. 4 Glock Model 21 that appears to have the recoil spring peen the underside of the barrel, about 1/3rd the length, and noticeable near the lug that holds the recoil spring end near the chamber. I bought this gun used, but in new condition about 4 years ago, and have only shot around 500-600 rds through it. I keep it well lubed and clean.
My 10 year old Gen. 3 Glock 19 does not have this issue, but it uses a plastic spring over the steel one of the Gen. 4. The air gap on the Model 21 between how the spring rides horizontally in relation to the barrel is adequate for not touching that I can see, I suspect that when the gun is fired it whip saws and strikes the barrel. I read that when these Gen. 4s came out they had issues with the springs?
Anyone notice this, sorry no pictures.
