Another endorsement for Tripp Research CobraMags. Simply the best of the best. There are several high quality 1911 mags out there, but the Tripps stand out above the rest. Not only are they well constructed, but their unique hybrid follower gives you the reliable smooth feeding of a polymer follower (such as Wilson's) AND the long-long term reliability of a metal follower. Dollar for dollar, the Tripp CobraMags cannot be beat. And on top of it all, Tripp ships to Canada without hesitation.
Great product, great company, great people to deal with.
