Check Mate Industries 1911 Full Size .45 ACP 8-Rd Stainless Steel Magazine

The Check Mate Industries 1911 Full Size magazine is a factory .45 ACP replacement built for full-size Government model 1911 pistols. Formed from polished stainless steel, this single-stack magazine delivers a standard 8-round capacity and drops directly into a classic Government-frame 1911.

Each Check Mate magazine is 100% developed and assembled in the USA and engineered around a hybrid feed-lip design paired with a welded base pad for long-term durability under repeated loading. The body carries a polished stainless finish and is mated to a high-performance spring for smooth, consistent cartridge presentation. The result is a factory-quality replacement designed for any single-stack full-size 1911 .45 ACP pistol of standard Government dimensions, and it is backed by Check Mate's lifetime warranty for reliable range training, defensive carry, and competition use.
