The Rock Island Armory Rock Ultra FS is a full-size M1911-A1 Tactical II pistol chambered in .45 ACP. Its steel frame and slide feature a durable black Parkerized finish, while gray G10 tactical grips provide a secure, textured hold. The 5-inch button-rifled barrel uses a full-length guide rod for consistent cycling and handling. A high-visibility fiber optic front sight pairs with a low-profile adjustable rear sight for fast target acquisition and precise sight alignment. The pistol also features a skeletonized hammer, an adjustable skeletonized trigger with an overtravel stop, and an ambidextrous thumb safety.
