Mec-Gar Colt Government 45 ACP 11-Rd Nickel Carbon Steel Pistol Magazine

The Mec-Gar MGCG4511N is an 11-round extended magazine engineered for the Colt Government (full-size 1911) and other standard 1911 full-size pistols chambered in .45 ACP. Built as a direct-replacement magazine to the original Colt Government dimensions, it seats in the factory-spec 1911 full-size magazine well.

The body and tube are formed from certified carbon steel with a durable nickel finish that resists corrosion and feeds smoothly. Inside, the heat-treated housing works with a heat-treated stamped-steel follower and a high-impact polymer floor plate, giving the magazine the strength to handle sustained spring compression without binding or deforming. With an 11-round capacity, this magazine provides extra rounds over the classic 7-round 1911 flush-fit magazine, making it a popular upgrade for extended range sessions and high-round-count training.

Compatible with any 1911-pattern full-size pistol - including Government Models, Commander-length pistols with full-size grip frames, and the many 1911-pattern pistols on the market - the MGCG4511N delivers reliable, long-term service as a quality replacement or spare magazine.
