Let me start off by saying I dont know much about these guns. I'm pretty knowledgable with guns in general but idk if these guns have any "quirks" and there maybe a simple solution. Went to the range last week and a good friend got his dad said handgun and when they went to shoot, it would constantly get a jam. The typical scenario was full mag, charge gun by hand by racking the slide and the round would feed fine. After you shot that first round, the 2nd round would get "stuck" were the nose of the bullet would be almost straight up into the top of the barrels chamber opening, *if I had to guess, it was a good 70-80 degrees angle. He first tried factory ammo and that happened. He then tried some of my hot 115gr and 147gr 9mm I shoot and it did the same thing...first round chambered by racking the slide (or just hitting the slide release), fire, 2nd round jam.
He dropped the gun off to me about an hour ago but I won't have a chance to look at it till this weekend. Also it has the factory mags.
