The thing about that is they are all made by someone else. And you don't always know who's providing their mags. Wilson of course being the exception as they make mags.
Adding to the list of the top mags, Wilson all ready mentioned, (ETM best) is probably the best out there, Tripp (Tripp Research, they're here in Texas also), Chip McCormick Power mags and others are good as well.
I use MecGar officers for my CC, I also have CMC (Chip McCormick) Shotting Stars (cheaper line) with either Tripp rebuild kits (spring and hybrid follower) or Wolff springs. I also have some Kimbers that once were made by McCormick, but the ones with the skirted followers but also with Wolff springs.
I've hear a lot of people say they really like the SPringfield mags as well. I think they're made by ACT Mag. They supply mags for a lot of people, Les Baer included I believe.
Wilson 47D's are great, however, my TRP would not for the life of me function reliably with them. PowerMags worked great in every 1911 I have run. Moral of the story, beg or borrow some to try in YOUR gun before plunking down for a dozen or so.
