I've tried several and am not loyal to a brand just because of the name. I go with what works. That said:
Tripp - easily THE most reliable magazine I've used. When I shot in a bowling pin league, I put thousands of rounds per year through about six different Tripp Research mags.
KimPro Tac - strangely enough, these have also been perfect for me. I've been waiting for one to screw up, but it hasn't happened yet.
Wilson - I've had two of them give me trouble. When that happened, I got rid of the six or eight that I had.
But, whatever works in your gun, use that and don't let us interweb know-it-alls tell you any different. It's your money, your gun, and your life.
