The M 1911 GI standard is a great representation of the original US GI combat issue 1911 and is chambered in 45 ACP and built with Rock Island Armory's exacting engineering standards. Fixed low profile sights and traditional smooth slim design are perfect for quick pull holster use. A durable parkerized finish gives it a tough smooth non-reflective surface. Smooth wood grips offer comfort in both feel and design. The 5” barrel offers a balanced weight to assist with the accuracy and recoil that made the original 1911 design famous. True to all Rock Island 1911s the GI Standard comes with a crisp factory 4- to 6-pound trigger for a great experience right out of the box.
