The Rock Island Armory M1911 Ultra pistol in 10mm with a 16+1 capacity (brand part no. 52009) brings double-stack capacity to the full-power 10mm 1911, giving shooters far more rounds on tap than a traditional single-stack design. Armscor/Rock Island Armory builds the pistol with a 5-inch barrel and a serrated slide, and a fiber optic front sight pairs with an adjustable LPA MPS1 rear sight for precise aiming. The safety system is fully ambidextrous, and the trigger action is single action. Among high-capacity 1911-pattern semi-auto handguns, this M1911 Ultra 10mm configuration favors shooters who want maximum caliber with modern capacity.
