Colt, or their equivalents from Metalform or Checkmate.
I've tried Wilson, McCormick, Tripp, MecGar, probably others i can't recall over the years. The only one that works in multiple brands reliably is Colt OEM magazines. Tripp would be my next choice, except their follower is sometimes too narrow to reliably hit the slide stop, unfortunately. I've tried at least three or four of each brand so as not to just get an off one and bias me.
