CM Products Match Grade 1911 Officer .45 ACP 7-Round Stainless Steel Magazine

The Chip McCormick Custom Match Grade 1911 Officer .45 ACP 7-round stainless steel magazine is built to tighter tolerances than standard military-spec mags—holding dimensions to +/- .001 inch, more than 75% stricter than typical GI magazines. If you shoot competitive 1911 matches, carry an Officer-sized 1911, or just demand reliable feeding from a precision-built magazine, this is the gear that backs up your trigger control.

CMC engineered these magazines from the ground up for consistency. The follower and feed lip geometry are refined beyond USGI specs, and the aerospace-grade wire spring maintains tension through hundreds of cycles. A welded stainless steel base plate replaces the traditional riveted design, eliminating a potential failure point and making disassembly cleaner. The smooth tube exterior slides in and out of a 1911 frame without catching, and large numbered witness holes let you count rounds at a glance—no guessing whether you're loaded to 7 or fumbling in dim light.

Match Grade means what it says here: tighter control in manufacturing, superior materials, and a magazine that feeds every round when you need it. Whether you're loading for the range, a sanctioned match, or serious carry, CMC's reputation for precision extends all the way down to the magazine well.
