The Rock Island Armory 51479 Rock Ultra .45 ACP 3.5" 8-Round 1911 Pistol is a compact duty and defensive firearm built on the proven 1911 platform, delivering the stopping power and reliability trusted by law enforcement and armed professionals for over a century. This 8-round, single-action .45 ACP is engineered for shooters who prioritize terminal ballistics and proven ergonomics in a shorter frame suitable for duty carry, backup roles, or personal defense.
The Rock Ultra's 3.5-inch barrel offers a balance between velocity retention and compact handling—ideal for those operating in vehicle-dependent or close-quarters environments where a full-size frame becomes impractical. Built by Armscor with traditional 1911 design fundamentals, the Rock Ultra features a steel frame and slide chambered in .45 ACP, delivering 230-grain performance with controlled recoil impulse and minimal muzzle rise thanks to the compact profile's lower bore axis.
Weighing 3.62 pounds unloaded, the pistol maintains the single-action crisp trigger and thumb safety controls inherent to 1911 ergonomics, allowing trained operators to deploy familiar controls under stress without retraining muscle memory. Law enforcement personnel, tactical operators, and personal defense enthusiasts will find the Rock Ultra to be a reliable choice for various applications.
