I only use USGI magazines with my AR-15 (M-16), because of their unparalled quality. If you bend the lip on these magazines...they become useless, they will not stay in.

What kind of 1911A1 do you have Tom? I recently picked up a Kimber Custom at the local gun show. Truly a reliable and fun to shoot pistol. Now I can't put the thing down! I just wish I were allowed to carry it on duty! LOL
