The Rock Island Armory TAC Ultra FS HC AOS is a high-capacity 9mm 1911-style pistol built for users who want the familiar controls and ergonomics of the 1911 platform with increased ammunition capacity. Its 5.05-inch barrel supports a stable sighting plane, while the AOS optic cut allows the installation of a compatible red dot sight. Glock-compatible front and rear sights provide a practical backup aiming system. The semi-automatic action, 16+1 capacity, manual thumb safety, and grip safety combine traditional 1911 operation with a modern double-stack format.
