Rock Island Armory 51485 Tac Ultra .45 ACP 5" 9-Round Pistol

The Rock Island Armory 51485 Tac Ultra .45 ACP 5" pistol is purpose-built for law enforcement, security professionals, and serious shooters who demand a reliable, full-size duty platform in America's most trusted caliber. With nearly three decades of Armscor manufacturing excellence behind it, this single-action 1911-pattern sidearm bridges the gap between budget-conscious acquisition and uncompromising combat-proven design. Whether you're outfitting a duty belt, establishing a backup system, or building a practical pistol collection, the Tac Ultra delivers the stopping power and ergonomics that field experience demands.

Built on the time-honored 1911 platform, the Tac Ultra features a 5-inch barrel that optimizes .45 ACP ballistics for barrier penetration and consistent velocity while maintaining a manageable overall profile at 8.2 inches in length. The 9-round magazine capacity maximizes firepower without sacrificing the slim, concealable grip geometry that makes this pistol controllable under stress. Checkered front and rear grip straps, a crisp single-action trigger, and a low-profile sight setup support rapid target acquisition and follow-up accuracy—critical factors in duty and defensive scenarios where split-second performance matters.

Law enforcement agencies, armed security professionals, and civilian shooters alike benefit from the Tac Ultra's proven reliability and affordability. The pistol integrates seamlessly with standard 1911 holsters, magazines, and aftermarket components, ensuring compatibility with existing duty gear and training ecosystems. At 4.03 pounds unloaded, it delivers manageable recoil impulse for extended training sessions while maintaining sufficient mass for controlled .45 ACP discharge. This is a workhorse sidearm—no frills, no marketing gimmicks, just dependable stopping power and combat-ready ergonomics.
