Rock Island Armory GI Series .45 ACP 4.25″ Barrel

The Rock Island Armory GI Series is a mid-size M1911-style pistol built around the traditional GI profile and chambered in .45 ACP for shooters who want classic 1911 ergonomics in a slightly more compact package. It is suited for range use, duty/carry applications, and general utility shooting where a reliable single-action pistol is preferred.

The GI Series features a parkerized steel slide and frame with smooth wood grips and a beavertail frame description that preserves the original 1911 silhouette. Fixed low-profile sights and a serrated slide provide a straightforward sight picture and positive slide manipulation, while the included single 8-round magazine matches the pistol's mid-size footprint.
