The M-1911 GI standard is a great representation of the original US GI combat issue 1911 and is chambered in 10mm and built with our exacting engineering standards. Fixed, Low Profile Sights and traditional smooth slim design are perfect for quick pull holster use. Finished with a tough parkerized matte coating and comes with checkered rubber grips. 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, making it a great experience right out of the box.
