ProMag Colt Government Magazine .45 ACP Blued Steel 10/rd

The ProMag Colt Government Magazine .45 ACP Blued Steel 10-round is a purpose-built extended magazine for the 1911 Government Model platform. Constructed from heat-treated blued steel, this magazine delivers the capacity boost operators and competitive shooters demand while maintaining the durability standards required for duty and training environments.

The magazine features a chrome-silicon spring wound and heat-treated for consistent feeding across varying ammunition types and environmental conditions. The follower and base plate are molded from a proprietary DuPont Zytel-based polymer, a material proven across tactical platforms for resilience and longevity. A polymer sleeve is included to protect the blued steel body from corrosion and handling wear. These materials work in concert to reduce maintenance burden while delivering reliable round stacking and feed presentation to the pistol's chamber.

The 10-round capacity addresses shooters seeking an extended magazine for the .45 ACP cartridge without excessive grip circumference increase. This capacity is suited for sport shooting, training protocols, and scenarios where additional ammunition on hand reduces reload frequency. The 1911 Government Model remains a platform of choice for law enforcement and civilian shooters, and Promag magazines are recognized as a reliable aftermarket solution for capacity expansion.

When comparing .45 ACP magazine options for the 1911 Government platform, capacity, material durability, and feed reliability are the primary evaluation criteria. This ProMag offering balances all three. The blued steel construction resists corrosion better than bare steel in humid or field conditions, while the polymer components reduce overall weight compared to all-steel alternatives.
