PROMAG MAG AR15 COLT 9MM SMG 32RD BLUED STEEL$25.48
Availability: In Stock
The Promag Cola37 is an 18-round 9mm magazine designed specifically for Colt 1911 pistols. If you run a 1911 in 9mm and want to maximize your round count without changing platforms, this blued steel magazine gives you nearly double the capacity of a standard single-stack 1911 mag. It's a practical choice for shooters who value the ergonomics and controls of the 1911 platform but appreciate the benefits of higher-capacity 9mm ammunition.
Promag magazines are a familiar option in the aftermarket space—they're built to mil-spec tolerances and designed to work reliably in the firearms they're matched to. The blued steel finish matches the appearance of most traditional 1911s and resists corrosion in the field. At 18 rounds, this magazine is significantly longer than factory 1911 mags, which will extend below the grip; if you carry or store your pistol, account for that extra length when choosing holsters or cases.
Whether you're setting up a 9mm 1911 for range sessions, competitive shooting, or home defense, having extra magazines on hand is part of responsible ownership. This Promag gives you capacity options without forcing a switch to a double-stack platform.
