Hey guys I have a 3-4 week old Gen 4 G19 that the day I bought it I went and shot 150 flawless times with the 3 factory mags only. A few days ago I put a OEM extended slide release lever on it, functioned fine while testing it locks strongly back with an empty magazine etc.. Today I shot it at an IDPA match and it would not lock back on the last shot, tried to correct my grip with no change, several different types of ammo, and several others shot it also and it still wouldn't lock back. I came home and stripped my G22 down (all stock) and it appears to be installed correctly and still locks back when manually pulled but not when fired. Surely my followers aren't worn yet? A little aggravated with it.

What happens if you put the original slide stop back in?

I tried that after I posted and same scenario happens.

Do you know anyone with the same Glock model that you can borrow some mags?
I dropped one at a range once and chipped the follower were it contacts the slide lock.

ETA: if you know someone with the same model, have them try your mags while you try theirs. If the problem goes to your buddy, you know it is the mags.

It is your thumbs mine do it too.... Just be mindful where your thumbs are. Ask me how I know I have long fingers and mine do this on my Glocks walther M&P .... 1911 and P7 are two that I do not have this problem.

Shoot it strong hand only. if it locks back then its your grip.

That was my first thought also.

Maybe his thumbs, but his friends too? Is it factory ammo? Recoil spring maybe? Did you oil it? Brand new, fouled with no oil could slow it up enough not to lock.

With a high, thumbs forward grip the 9mm sized Glocks will have slide stop issues with many shooters. my thumbs are actually higher than the slide stop and its the palm of my off hand that can ride it if i am not carefull not to. and thats with the standard part. Extended Glock slide stops dont work for me at all.

They don't work for me either. The palm of my hand will sometimes bump the entended slide stop upwards, causing the slide to lock back with rounds still in the mag. All my Glocks have stock, non-extended slide stops now, even my 34's.

Buddy of mine who is a 1911 shooter just bought a G34. After the first range trip i gave him a standard slide stop for the same reason.

I know that was my first guess, but he said he and his friends along with gripping it differently. Usually high thumbs lead to locked slides not slides that don't lock.
