I was wondering if someone could help me figure this out. I want to use a 1911 .45 for IPSC and would be using 10 round mags. Would that put me in Limited 10? If not, what class? Would I be competing with those race guns with my 1911? I have a 9mm that I could use, but I shoot better with the 1911. I tried to access the USPSA website but could not get it to load.
