    I had this happen to me the other day at the range. Been shooting glocks along time. Have extended mag release never had a problem. Then was shooting rapid fire and it started happening I was inadvertently hitting slide stop with my thumb. You are right 98% of the time that’s what it is.

    I stopped using extended slide stops long ago. A little filing of the surface that engages the notch in the slide with a jewelers file makes disengaging the stop easier.

    98% of the time, statistics are made up 36% of the time, all the time....

    In all seriousness, the RMR came off this guy and it got thrown in the back of the safe. Same problem with new mags, new RSA and left hand shooting after 2 deep cleans.

    WOW 2016 Old thread, still not fixed??

    If happening when shooting with the left hand, less likely the thumb.

    Didn't read all, but the next thing to check is the slide release spring, make sure it is under the trigger pin, and not broken, or assembled incorrectly.

    I think he said he put the OEM slide stop lever back in and the problem went away. My first guess would have been since it's a chopped 17 to 19 grip, he's off a little on the chop...just enough for it to be unreliable.

    It started doing it again with factory OEM slide release.

    So to summarize, bought the G17 brand new and the first thing i did was put in glock extended slide release. Shot it thousands of rounds then out of nowhere, premature slide locks back.

    Throw in never used factory oem slide release, fixes problem for a very short time and then im back to slide release locking back prematurely.

    *Notes*
    I have tried shooting it left hand for dozens of mags and my son has shot a few mags left hand and it acts the exact same way.

    The grip being cut too short makes no sense because by that logic a 33-round magazine would do the same thing.... You should be able to cut the grip all the way down (or up)to the bottom of the trigger guard and it still function 100% correct.


    Im about ready to scrap the frame, sell the slide and start with a fresh G17G5 because im completely out of ideas.

    Even if i did throw another brand new oem slide release onnit what is to say it is not going to start doing the same thing in a couple months just like the last one did?

    Are you planning to screw up that new G17 Gen5 as badly as you did the G17 Gen4? Was it worth it?

    Yes I am. With the 10k plus rounds through 10 different tactical pistol/rifle classes, it served me well while it lasted.

    Thanks for the reply!

    Mike, please, due respect, but what problem were you initially trying to solve?

    Mike, so what you wanted was a 19 grip but a 17 slide?
    You need to start looking at SIG P320s; lots of alternate 'grip modules' to fit on a FCG.
    Yeah, I know, wrong forum...;)

    Yeah, 365 is my go-to as well. Really no bigger than a G42, hard combo to beat. :)

    I've read through this whole thread and a couple others. Just looking for thoughts on what might have caused a lockback on a brand new completely stock G19 gen 5 right out of the box in the first mag through it. Locked back with a couple rounds still in the mag. I've had a gen 3 G19 and two gen 4 G19's and never had this problem with any of them.

    I looked close at the slide lock spring and it seems to be in correct position and seated right. The gun had never been disassembled before shooting it. I will check my grip although I don't believe it's any different than the other G19's I've shot. I would try some left hand shooting but since the Gen 5 is an ambidextrous slide stop I don't think it would make a difference. Ammo was 115gr FMJ Aquila.

    My own personal best guess is my thumb has gotten fatter :eek: but I'd appreciate any other opinions.

    Remove the slide lock from one side of the gun and shoot it. That will tell if it's you or the gun, definitively

    Simply remove one or both of the slide locks from the gun and shoot it with the corresponding hand. Not following what you're not following.

    The two sided slide lock is all one piece, and the right hand one depends on the left one engaging the magazine to function, does it not?
