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 our 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 4.25 barrel offers a more compact format for carry while helping you maintain accuracy. 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.
