The Rock Island Armory Tac Ultra FS HC pistol in .45 ACP with a 5-inch barrel and 13+1 capacity (brand part no. 57171) brings double-stack, high-capacity magazines to the classic 1911 platform. Armscor/Rock Island Armory fits fixed sights on the 1911 slide, and the single-action trigger delivers the crisp break 1911 shooters expect. One 13-round magazine ships with the pistol.
