If you run a 1911 Government in .45 ACP and want reliable, mil-spec magazines that actually work, the Mec-Gar MGCG4510B is built to the standard that professional shooters and military units have trusted for decades. This blued steel 10-round magazine delivers the capacity and dependability you need whether you're at the range, hunting, or carrying for personal defense. Mec-Gar has spent years refining 1911 magazines to handle the demands of serious shooters—and this one carries that reputation without the premium price tag of some alternatives.
The magazine is engineered with heat-treated precision-stamped construction and reinforced feed lips designed to strip rounds reliably under real-world conditions. Every critical dimension is held to tight tolerances and regularly validated during production, so you get the same exacting quality that armed forces and law enforcement have relied on globally. Whether you're loading full-power .45 ACP or running softer loads, this magazine handles the job without drama.
For 1911 shooters who buy backup magazines by the handful, Mec-Gar offers the sweet spot between performance and value. Ten rounds of on-demand .45 ACP capacity in a mag that won't let you down.
