Glock 19, slide lock headaches

[rcrown]

Hello all, I carry a Glock 19 Gen 4 and just recently ran into a problem during quarterly qualifications with my slide not locking back after the last round has been fired. I have went through this gun, cleaned toughly, and inspected for damage parts. I am not finding anything, has anyone else experience this with any of their Glocks? If so, what did you find and how did you repair it?
Thank you for your suggestions and help.

Hi Ron. Assuming all the parts on your G19 are fine and the slide locks back fine when you manually cycle it with an empty mag, I'd suspect either you're limp wristing it when shooting, or you have a bad batch of ammo that's too weak to cycle the slide all the way back for the slide lock to engage.

Is it possible your thumb is touching the lever and keeping it from engaging?

.cleaned toughly..

That's the spirit, tough love, tough clean, baby!
Probably the magazine follower not pushing up the slide stop far enough. Remove the slide and check.

Thumb overriding the slide stop?

If the Slide Stop Spring gets slightly bent it can hold the SS down.

I tend to ride the slide lock alot on my g 19.

Thank you all, it is possible my thumb is messing with it. I have never even consider the ammo, I will stop and pick up a different box/brand of ammo and see how it reacts.

shoot it left handed and see if you have the same problem.

like 200 other people have suggested, its probably your thumbs

Any chance you removed the trigger or any related pins recently?
