Rock Island Armory M1911A1 GI Standard in .45 ACP with a 5 in barrel, polished nickel steel frame, smooth wood grips, fixed sights and an 8-round magazine. Full-size GI-spec 1911 with beavertail safety and serrated slide.

The Rock Island Armory M1911A1 GI Standard is a full-size, steel-frame 1911 built to reflect the classic US GI profile. Chambered in .45 ACP with a 5-inch barrel, it pairs traditional lines—smooth wood grips, beavertail frame and fixed low-profile sights—with an authentic operating feel. For a modern sighting option, a compact reflex such as the Holosun 507C (a sub-$1000 reflex commonly used on duty and competition pistols) can be fitted via an appropriate slide plate or gunsmith installation.

Typical uses include precision range/target shooting and historical/collector use where period-correct ergonomics and appearance are valued.
