Rock Island Armory Tac Ultra Fs .45 ACP 5" 1911 Pistol

The Rock Island Armory Tac Ultra FS .45 ACP 5" 1911 Pistol (Model 57166) represents a modern refinement of the proven 1911 platform, engineered for operators and shooters who demand reliable duty-grade performance in a classic format. This full-size, single-action semi-automatic pistol delivers the stopping power and ergonomics that have made the .45 ACP a professional standard across law enforcement, military, and civilian tactical communities. Built on a modern steel frame and slide, the Tac Ultra FS is designed for shooters seeking a balance of accuracy, reliability, and practical carry weight without unnecessary complications.

The 5-inch barrel configuration optimizes the .45 ACP cartridge for consistent velocity and accuracy at tactical engagement distances while maintaining a manageable overall length of 8.5 inches—suitable for both duty rigs and concealed carry setups. Rock Island Armory's Tac Ultra line incorporates a flat-profile trigger geometry that enhances control and shot placement consistency compared to traditional curved triggers, critical for precision work under stress. The full-size frame provides superior ergonomics, recoil management, and a longer sight radius, while the steel construction ensures durability and longevity in high-round-count training and professional environments.

This model serves law enforcement personnel, military shooters, defensive-minded civilians, and competition shooters who prioritize reliability and ergonomic handling over modular customization. The Rock Island Armory Tac Ultra FS accepts standard 1911 magazines and parts, ensuring compatibility with established accessories, holsters, and duty gear ecosystems. At approximately 1 pound, the pistol balances weight distribution for reduced fatigue during extended wear while maintaining the inherent recoil control advantages of steel construction—making it ideal for training programs, duty carry, and serious defensive application.
