MEC-GAR MAG COLT OFFICER 45 6RD NKL

Description

Mec-Gar has manufactured magazines exclusively since 1965, and that single-product focus shows in how this one is built. The MGCO4506N is made specifically for the Colt Officer-size 1911 platform — a shorter-grip frame than the Government or Commander — where the compact dimensions demand a magazine engineered to those tighter specifications rather than a full-size unit trimmed down. Fitting an incompatible magazine into an Officer-size pistol is a common cause of feed failures, so the precise fit here matters in practice.

The body is heat-treated carbon steel, which resists the deformation that can open up feed lip geometry over time and with repeated loading cycles. Consistent feed lip spacing is what keeps rounds presenting at the correct angle to chamber reliably; when those lips spread or compress, feeding becomes unpredictable. The steel follower and spring work together to maintain consistent upward pressure through the full round count. The nickel finish provides a corrosion-resistant surface and reduces friction as rounds strip from the magazine during feeding — useful in humid conditions or for a pistol carried regularly.

This magazine holds six rounds of .45 ACP, which is the standard capacity for the Officer-size frame. It is manufactured in Italy and built to the same tolerances Mec-Gar supplies to military and law enforcement contracts. If you are running an Officer-size 1911 and want a spare that feeds as reliably as the factory unit, this is a straightforward choice backed by a manufacturer whose entire business is making magazines and nothing else.
