ProMag Colt Defender Magazine .45 ACP Blued Steel 7/rd

The ProMag Colt Defender Magazine .45 ACP Blued Steel 7-round is purpose-built for shooters who demand reliable ammunition feeding in the venerable Colt 1911 platform. Whether you're running a defensive carry gun, competition pistol, or duty weapon, this magazine provides the dependable performance that law enforcement and military professionals expect from their backup magazines. A seven-round capacity balances magazine footprint with practical firepower for modern .45 ACP applications.

Built from blued steel, the ProMag Colt Defender magazine delivers robust construction resistant to corrosion and wear during field use. The seven-round configuration feeds reliably through the tight tolerances of 1911 magazines, with followers and springs engineered for consistent lock-back on the final round—critical for tactical reloads and administrative unloading. The compact profile (5 x 2.95 x 9.1 inches) maintains the low-profile aesthetic of defensive carry while providing enough capacity for immediate threat response. ProMag's manufacturing standards ensure dimension accuracy and feeding reliability across varying ammunition weights and construction types common in .45 ACP loadings.

This magazine is ideal for Colt 1911 variants, including M1911A1 clones and modern defensive platforms chambered in .45 ACP. Off-duty officers, armed civilians, and competitive shooters benefit from carrying multiple magazines for reload capability and training scenarios. The blued finish pairs seamlessly with traditional 1911 aesthetics while resisting holster wear. At 0.2 pounds, the loaded magazine contributes minimal weight to carry systems, making it practical for extended duty or daily defensive use.
