I was shooting Winchester .40 caliber 165 grain ammo today and the brand new Glock 22 had an issue. I saw the pin near the trigger guard housing sticking out the right side of the weapons frame slightly. I poked it back in and at the same time noticed the slide locks on any action of the gun. This is without ammunition and dry cycling.

What is causing this issue? Thank you!

If it has an empty mag in it then  it is normal for the slide to lock back. It's supposed to do that when out of ammo in the mag.

That pin will not slide out when the slide is on it.

Fixed the issue.

Broke down the slide and looked at the pin after removing it completely. There is a small spring that is held down by the pin, that spring was not being held down by the pin, the pin must have moved enough for the spring to compress and stay above the pin. Placing the pin under the spring while sliding the pin through the frame fixed this issue.

The spring for the slide lock (or slide release, whatever you want to call it) rests on the bottom of that pin, pushing it downward onto the frame.



When the pin came out, the tension was lost.





1. Take the slide off.

2. Remove both pins near the trigger (normally you should always remove the bottom pin first, but if the spring isn't underneath it, it probably doesn't matter)

3. Take out slide lock, verify spring isn't broken.

4. Replace top pin in first (known as "locking block pin")

5. Replace slide lock

6. Replace bottom pin  (known as trigger pin)

Well I had the right answer, just too slow.   Day late and a dollar short, as always



 

Thanks anyways, while we are on the topic, is this a common occurance with Glocks? This glock is fairly brand new, less than 100 rounds when this started to happen.

I usually only hear of it after somebody took it apart and put it back together in the wrong order.



Ive never seen one that just walked out on it's own.

Haha, well atleast I can say my LWRC rifle has not failed me one time, and a brand new factory glock has issues in less than 100 rounds. GO LWRC!
