Check Mate Industries 1911 Full Size .45 ACP 7-Rd Stainless Pistol Magazine

The Check Mate Industries 1911 Full Size magazine is a .45 ACP replacement magazine purpose-built for full-size Government Model 1911 pistols. Machined from American-milled stainless steel and high-carbon steel with a through-hardened tube, this seven-round magazine delivers the durable, factory-quality performance Check Mate is known for, backed by their lifetime warranty.

The flush-fit 7-round profile is optimized for modern hollow-point defensive loads rather than 230-grain FMJ ball ammo. Precision-witnessed feed lips and a quality spring assembly help ensure reliable feeding across a wide variety of bullet profiles, while a removable polymer base pad makes field stripping and maintenance straightforward.

Designed as a direct-fit replacement or spare for full-size Government 1911 pistols chambered in .45 ACP, this stainless magazine is proudly made in the USA from high-quality American steel and finished in a corrosion-resistant stainless tone.
