I put 100 rounds through my new RIA. I had 2 maybe 3 failer to chamber and it was always the last round in the magazine. Would this be a magazine issue or the gun? I've also heard that even higher-end 1911s might do this. Any advice would be helpful. Thanx! Love my 1911 by the way. My first and certainly not my last. Wanna kill these ads? We can help!
