Pharma - Wilson Combat mags for the 1911 are my new best friend. The Chip McCormick mags are good, but they just didn't feed reliably in my 1991. The problem was that the feed angle wasn't consistent because of the design of the follower. The less compression on the mag spring, the steeper the angle, to the point that on the second to last round, I'd fairly consistently get stove pipes. the Wilson mags have a one piece polymer follower that doesn't change angle regardless of the spring force. So far a few thousand rounds through it without a single stove pipe.
