Glock getting stuck

[nwhpfan]

I've been hesitant to post this because I suspect a number of "it's the slide lock." It's not, because it's doing this even with it removed.

My G3 Glock 26 is getting stuck at lock back. If I smack it in the back of the slid it will pop forward. If I sling shot it as hard as I possibly can it will usually go forward.

I have replaced every single part (except the locking block) one at a time to see if the issue is resolved. Recoil spring, slide release (in or out), striker, plunger, ejector housing, trigger, etc.

There is no apparent obvious wear or rub marks.

The gun is a few years old. I won it in GSSF and used it in sub-compact the last few years. I probably have 2-3 k through it. It had been my CCW until this.

You input is appreciated. Thanks.

Does it happen with the mag out?

Have you checked you barrel for bulges?

[HeavyDuty]

yes.

That’s interesting! It may be time to break out high intensity lighting to see if you can find the interference point.

I wonder if the frame is tweaked. Do you have access to another 26 to play slide swap?

I just did and I don't see anything that stands out....however, the barrel does not appear to move freely within the slide when disassembled...

I'll have to get my hands on another bbl to check further and verify.

Thankyou.

I kinda do and am going to check that out tomorrow.... I did think that perhaps one of the frame rails was out of whack...but right now I think it's the bbl.

Thanks!

Please report back!

Did you try inserting the barrel muzzle first from the front of the slide? Does it go in all the way the the chamber and move freely?
