I cannot figure out what's causing it.
It has been cleaned and lubricated, including the trigger group.
I have updated the dog follower spring and hammer spring.
I just ran about 80-100 rounds through this without this problem.
Then now for some reason, about every 3rd round the action sticks shut, but NOT if I pull the trigger and pump.
It only sticks if I use the slide release to cycle the rounds.
It doesn't stick every time, it's random but repeatable.
I've had it apart more than once and I cannot find anything wrong.
I'm just stumped.
The video is using real weight dummy loads, but it does the same thing with Hornady Critical Defense and a few others.
Again firing live and pumping it this doesn't happen. Only when cycling the round with the slide release.
