Mine started out as a 1911 in .38 Super. Shot that a bit, then came across a 3-book/magazine series on the .45 Auto. I installed a Wilson .45 Auto bl., new link, bushing, ported the slide as noted in one of the magazines, bought some 11 round mags. and had a blast.
Shot 2 "trouble" black bears with it while at work. They were chasing the night staff around a bit.
Shot 8 one fall.
