I was at the range yesterday and my 1911A1 wouldn't feed properly. The bullets would jam at an upward angle and stay pinched between the barrel entrance and the next bullet in the magazine line. I examined it when I had returned home and found a line of brass on the slide catch which indicates that the bullets were rubbing on it. Is this normal? I know that the slide catch is responsible for holding the slide open and holding down the follower in the magazine but I was wondering if it served any other purpose? Would modifying the slide catch so that the bullets stop rubbing be a good idea or would I be screwing up something else in the process that I am not aware of? Any thoughts on this matter would help a great deal. Thanks
