Glock 29 slide locking back after every shot

July 20, 2017, 08:31 PM

I have a new gen 4 glock 29 that worked just fine until I installed a new trigger and take down lever and ghost extended slide stop. The slide locks back after almost every shot or every 3 or 4 shots. During a function check while empty everything seems fine. Slide closes without a mag in and locks back with an empty in there and also if loading with slide back or slide closed it everything is as it should be until I shoot it.

I'm going to put the stock slide stop in there and see what it does. I'm thinking maybe I put it back together wrong?

I'd rather be hated for who I am than loved for who I'm not.

I stick with stock parts for exactly this reason.
For the life of me, I can't think of a reason for an extended take down bar for a Glock. The stock one works fine for the once a year you take it apart to clean it. Also, the 0.0001 seconds faster that the extended one might be isn't worth the worry that it might not function properly (and send a slide flying into your face under recoil).

Glocks like stock.

YMMV,

Make it totally clear to anyone standing at the wrong end that things are going badly for them. If that means sticking all sort of spikes and prongs and blackened bits all over it then so be it. This is not a gun for hanging over the fireplace or sticking in the umbrella stand, it is a gun for going out and making people miserable with." -Douglas Adams

The slide stop spring bears against the locking block pin. If the slide stop is put into the pistol before the locking block pin, the spring lacks sufficient tension and this is why you get the premature locking after every shot.

Here's a little Glock assembly ditty for you:

The top pin is the locking block pin.
It's the first one out and the first one in.

Remember this and you won't again put it back together incorrectly.

Take the top pin out.
Take the bottom pin out.
Take the slide stop lever out.

Make sure the spring is not bad.

Install the TOP pin first.
Put the slide stop lever in so the spring goes under the top pin.
Put the bottom pin in.

I call the top pin the FIRST pin, no matter what.

Yep, what Para and Phelen_Kell said. If it's still doing it after installing the slide stop in the correct order and sequence, only then you can start suspecting the aftermarket part as being the problem.

You put the top pin in, you put the slide stop in, you put the bottom pin in, and you shake it all about...

You do the Glocky-Pokey, and you turn your gun around.

That's what it's all about.

Once you get it working right, you may find that you will still have problems with it.

I had to take the Ghost extended slide stop out of my G32. I kept bumping it under recoil. I didnt do that with the factory slide stop.
