The M1911 GI standard is a great representation of the original US GI combat issue 1911 chambered in 45 ACP and is built in Rock Island's top quality production and engineering standards. Fixed low profile sights and traditional smooth slim design are perfect for quick pull holster use. A durable parkerized finish provides it a tough and smooth non reflective surface. Smooth rubber grips offering a comfort grip that can be appreciated by any in both feel and design. The 5" threaded barrel offers a balanced weight assisting with the accuracy and recoil that made the original 1911 design famous. True to all Rock Island 1911's, the GI Standard comes with a crisp factory 4 to 6 pound trigger which makes this fine pistol a great experience right out of the box.
