Only have 2 45's One is a 1943 Ithaca 1911A1 I got in a swap session from a WWII vet. The other is a Springfield Armory 1911A1 with all the bells and whistles. Started shooting the Ithaca in steel plate matches as it was the only 45 I had at the time. Then found the Springfield Armory a year or so later. I've shot only hardcast 230 grain round nosed bullets in both. I'll play around with my 9mms. But always come back to the 45's. Frank
