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 nonreflective surface. Five-inch threaded suppressor-ready barrel. 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.
