I purchased a kimber 22 converion kit for my 70 series 1911. I was about to go to the range, so I installed the slide on my frame a stuck the magazine in. It would not seat in unless I locked the slide back. But now the slide does not drop, it seems like the magazine is seated so high it blocks or rubs against the slide. I purchased 2 extra magazines and had the same problem. I had a old mag from their earlier version made by ciener and the mag seated fine and the slide retracted smoothly with no binding. has anyone had this issue? I called kimber and they never hears of the problem.
