My 1911 has on three occasions ejected an unfired round, two this AM at a range session. I load five and count shots, the first I didn't know until the slide locked open after four. The second occasion the round bounced off my chest and landed on the bench. One last week hit the dirt in front of the bench. They all load and fire normal when reloaded. I'm assuming a magazine problem as the gun doesn't jamb. I have several mags so haven't had a chance to stick with one at a time to see if that's the issue. Its a 200 grain SWC load I have fired for many years from this same piece. Any others experienced this. My shooting buddy has the same gun, shoots the same load and has never had this happen.
