The Rock Island GI Standard 1911 pistol in .45 ACP with a black parkerized finish (brand part no. 51473) is a faithful representation of the original US GI combat-issue 1911, built to Rock Island’s top-quality production and engineering standards. Armscor/Rock Island Armory builds the GI Standard with a 5-inch threaded, suppressor-ready barrel and a serrated steel slide, and fixed low-profile sights pair with a traditional smooth, slim design perfect for quick pull holster use. The durable parkerized finish provides a tough, non-reflective surface, and a beavertail frame with black rubber grips rounds out the classic package. True to all Rock Island 1911s, this GI Standard ships with a crisp factory 4-to-6-pound trigger for a great experience right out of the box. Among classic semi-auto handguns, this GI Standard configuration favors 1911 shooters who want an authentic, suppressor-ready platform.
