I have read hundreds of references on proper 1911 function and they all say that, with a standard two piece ramp, add the round is stripped from the magazine it hits there frame ramp and tilts up and into the barrel.
My 1911 does not do this. With GI, CMC, and WC magazines, the rounds sit high enough so that as they are stripped off the round just barely touches the frame but mostly contacts the barrel ramp and rn bullets slide right into the barrel. Any lead bullet with a flat nose profile like a swc will jam right into the leading edge of the barrel ramp and stick there at least half the time (4 of 8 rounds). The ramps are mirror polished but since the bullets never contact the frame ramp that doesn't help. Any ideas?
