    I just got my Gen 4 G29. Brand new. I love shooting it.

    But I'm having the same problem as I do on my Gen 3 G20.

    The slide doesn't stay open after the last round is fired. This was a brand new gun. I fired 100 rounds maybe. Everything is stock on the 29.

    Is this a coincidence or something I'm doing? Like limpwristing or the opposite I guess would make more sense.

    Have you disassembled the trigger group by removing the cross pins, etc.?

    I'm thinking maybe the slide stop lever spring might not be in the correct position. But what do I know :cool:

    Yes, and....

    Please mention what munitions you are using.

    Are you limp wristing it? That can cause those issues just like a stovepipe.

    or you are holding down the slide catch with your thumb.

    Also weak ammo will give you fits with a glock.

    I have taken the 20 apart and checked the lever spring. It's under the top pin.

    Different mags. If I hand-rack, both stays.

    I was using DT 180gr advertised as 1350 I think out of a 5" barely. As well as some of my own hand loads. All of them on the warmer side.

    It'll take me another outing to figure if I'm limping or squeezing the slide stop.

    I'll take them both apart and double check everything....

    If the same thing is happening with two Glocks, the common thing between the two is YOU. Your support thumb absolutely must be holding the slide catch so it does not push up into the slide upon empty mag.

    I had the opposite problem and was pushing up my slide stop in the middle of a mag. I had actually installed extended versions of the part. I went back and put in the originals so I didn't do that during a DGU.

    It has to be user error. Not conscious, not a skill issue. I'm not admonishing you or anything. But it sounds to me like you may need to look at the placement of your support thumb.

    ^^^Along the same line, all of my Glocks shoot low and left. Pretty sure it's not the Glock at fault. :eek::D

    Now, now! Let's not be hasty to assign blame!

    They are Glocks after all! There could be rodent scat around the slide stop or any number of other bugs involved!:D
    Hope you get it worked out!:)

    Hold it tighter...
    Does it do it when you use a two hand hold?

    My buddy has the same issue with the two Glocks he owns. He is right handed and it happens almost every mag. Now, I'm left handed and can shoot both of his and both of mine and the slide locks back every time. Point? His thumb and most likely yours are resting on the slide stop.

    Yea, after scrutinizing my grip I must admit the likely hood of that being the problem is pretty darn high.

    Lol - after years I'm now trying to get comfortable without squeezing the slide stop. It was so comforting :)

    I never had the problem with Glock, but SIGs were another story.

    Floppy thumbs.

    A 1/2 to 3/4" wide piece of stair tread tape, stuck below the slide release can give the thumb something to "stick" to.

    Also, check out the grip style that places the right thumb on top of the left thumb as both thumbs point at the target, parallel to the barrel. Putting a little pressure of the right thumb down onto the left one can help secure this wayward digit.
