I got two Mec-Gars with a Charles Daly that I bought about a year and a half ago. In my experience they fed hardball as well as anything else, but the gun or the mags constantly choked on hp's. I got a couple of Chip McCormick shooting stars and it seemed to help alot. Metalform also makes good magazines, and of course Wilson Combat are the apex of 1911 mags. Just my .02.
