I have a rock island gov 1911 with about 250 rounds down the pipe, I haven't had any problems until my last range session, with a fully loaded 8 rd magazine the 1st round would get 1/4 inch out of the chamber and stop with the slide still kicking back and trying to load the next round causing a type 3 failure. I am thinking it is because my magazine(kimber)is a POS and causing to much upward pressure. could this be a cause?
