The Rock Island Armory Tac Ultra FS 45ACP 5" 8+1 AOS is a full-size 1911-style pistol built for shooters who want modern capability in a familiar platform. Its steel frame, black parkerized finish, and aggressive slide serrations give it a purposeful look, while the AOS optic-ready slide and accessory rail open the door for lights, lasers, and red dot sights tailored to your needs.

This single-action .45 ACP pistol uses an 8-round magazine and a 5" barrel for classic 1911 balance and recoil characteristics. G10 grips, a beavertail grip safety, and ambidextrous thumb safety support confident handling and control, making it well suited for range work, training, and responsible home defense. The combination of fixed sights, reliable operation, and thoughtful ergonomics reflects Rock Island Armory’s focus on practical performance and solid craftsmanship.
