Problem with my glock

[Bobula]

I was cleaning my glock today when I noticed some abnormal wear on my slide and frame.




There was not cracking visable anywhere, but there's a spot on the frame where the guide rod is scraping it, close to the take down pin.
It has me seriously worried. Any suggestions before I take it to a gunsmith?


sorry my camera has no macro setting, you can see where the shiny spots are though.

Peening on the slide, completely normal. It is more prevalent on the 40 caliber glocks, but it stops at a certain point. Keep shooting it and don't worry about it. It is caused by the locking block, but it hurts nothing.

Send it to me and I'll dispose of it properly.

What are the shiny wear marks/divots on the bottom of my slide?

Did the guide rod slip off its seat in the barrel lug? It normally shouldn't contact the slide.

THANKS! I'd never noticed them until I cleaned it today. I've cleaned it more times then I can count, just must not have noticed them.

Just leaves the one problem

I'm pretty sure they're unrelated, The rear of the guide rod appears to be dragging on the frame. There is a cone shaped indentation where it looks like the guide rod was rubbing the frame.

Is it an aftermarket guide rod? When was the last time you replaced your recoil spring/assembly? The Glock factory take on when to do so is 2k rounds.

[Bobula]

it's the factory one. Good lord after 2k?!?!?! Mine's had over 10k since I bought it......

Its not caused by the recoil spring, its the locking block coming into contact with the slide.

Along those lines, how does one change the spring on a newer Glock with the captured spring? Do you get a whole new assembly?

My old G22 had an non-captured spring but I put it on an Aerotek guide rod, the spring is probably dead. Wonder if I can pull the endcap off the rod and reuse it.

That is called slide peening caused by the locking block hitting the slide during cycling. It should stop after a 500 rounds. If it continues call Glock and they will inspect and replace. Problem with that is that the serial numbers will not match afterwards. This happens on the higher calibers with Glock and is never seen with the 9mm ones. Glock actually feels this is normal. Hope that helps.

To change the spring, just buy a new one. The oem recoil springs are about 2$ for fullsize and compact for the complete assembly, or if you want to experiment with spring weights, go with a stainless steel guide rod from someone like glockmeister that allows you to change springs.

Since there's some better knowledged people then me in here, How much of a PITA is it gonna be to put in a 3.5# connector?

Super easy! Takes maybe 5 minutes. Possible 7 minutes the first time you take it apart.

While you are in there, do this:

Especially after you watch someone else do it first huh?
