    Glock 23 premature slide locking back

    Today I took my son shooting. It was his first time with handguns (he's 18). We shot 125 rounds of federal 180gr fmj factory ammo. I have had this gun for a while now, it was made in 2002 and is a Gen 3. My son had the slide lock open once when the mag still had rounds in it. I had him hit the slide lock and it chambered the next round and he finished the mag. I figured he rode up on the slide lock.

    Then I shot some rounds and it did it to me. It isn't a stovepipe or failure to feed, the slide lock is engaging so that rules out limp wrist. And this is the first time this has happened. Could it be a weak slide lock spring? Only variable is I brought a new to me glock factory mag, but I didn't look to see which mag had the malfunction. Could a bad mag cause that issue? Last range trip I only had one mag with me and had no issue.

    Thoughts?

    The mag could cause that issue, but I kinda doubt it. My bet is thumbs were riding a little high on the frame engaging the lever without you knowing it.

    Wouldn't the mag follower have to engage the slide lock for it to be a magazine issue?

    It's a Glock, they are Perfection!
    So it cannt be the pistols fault.
    Or can it?

    Need to try to repeat the problem. Be sure of your grip and thumb placement.
    And use several mags if possible. Odds are if it repeats itself with several mags then the issue could be the spring.

    spring on the slide stop is broken.

    Pop your 3 pins, guarantee its the wire spring connected to the slide stop.

    SUPPOSED TO LOOK like this.

    Easy test…..Push up on your slide stop lever and if it stays in the up position. Its broken.

    This is also an obvious/likely answer. Its probably long over due for replacement, your gun is 12 years old.

    The slide stop moves up and returns to its position, but does feel a bit weak. The Glock armorer at the range said it felt fine. I guess maybe it was me riding it high, but it has NEVER happened to me before (except my G27 that had a broken spring) on any of my Glocks......Gen 4 19 and 23 and this Gen 3 23.

    My other Glocks are being used by my brother in law, I don't have them here right now. Anyone with a Glock care to look at your slide stop and tell me if mine is pointed out too far on this one? I think that might be the issue........

    Sounds like the curse of the high thumbs shooting style strikes again.

    I shoot my autos like I do my revolvers...support hand thumb over shooting hand thumb. Keeps the thumbs away from cylinder gaps, slide lock levers, and the slide itself. In many thousands of rounds, I have never had premature slide lock open.

    When I had that problem with my Mod 21 it went back to the factory. The only original parts I got back were the slide and the bbl. Everything else was brand new. Call the factory and talk to a gunsmith.Super service!

    I could completely agree with this, except I have put 1000 rounds through my Glocks in the last year and never had it happen. I dunno, maybe I'm over gripping the snappier 40 cal glock?

    Saw in the pic that the grip is stippled. Has it been trimmed as well? Are your other Glocks modded in the same way? Do you grip them all the same?

    Both my 23s are stippled, not reduced or modified beyond that. Both have the grip force adapter as well. The more I look online the more it seems my slide catch is bent out away from the frame more than other Glocks. Wish I had my other one handy. May have to drive across town, the curiosity is killing me
