Upon close inspection I believe the slide is being hung up on the barrel as well as a bump forming on the bottom of the slide. With the crack in the chamber it expands. The bump between the bolt face and the striker has a small bump. The gun is failing at 2 points
I have 1, and It out shoots my 1k Compton pistol. My friend, who does 3 gun competitions, used it, and he liked it. I had many, many firearms. And shot a lot.
