Mag Act-mag 1911 45acp 13rd

The Armscor Mag Act-Mag 1911 45 ACP 13-round magazine is a high-capacity double-stack magazine engineered for Armscor and Rock Island Armory full-size 1911 platforms chambered in .45 ACP. Manufactured to exacting Italian tolerances, this magazine delivers the reliability and fit demanded by serious shooters who run full-size 1911 duty or competition rigs and need capacity beyond single-stack limitations.

Construction is all-steel, fabricated to Armscor/ACT MAG specifications using the same manufacturing processes and materials as factory original equipment magazines. The 13-round capacity represents a significant increase over standard single-stack 1911 magazines, providing additional combat or competition rounds without requiring a reload. Steel construction resists corrosion and handles repeated cycling from both semi-auto and manual charging without deformation. Feed reliability is ensured through precise spring tension and follower geometry designed specifically for .45 ACP cartridge dimensions.

This magazine serves operators, competition shooters, and duty users running Armscor or Rock Island 1911 platforms who prioritize round count without sacrificing fit or function. Double-stack geometry increases load capacity while maintaining reliable feeding; the design is ideal for extended training sessions, tactical scenarios, or IDPA/IPSC competition where magazine changes represent a time cost. Compact footprint relative to capacity makes it practical for serious 1911 shooters unwilling to compromise on platform choice.
