Rock Island 51470 Tac Ultra Compact | .45 ACP | 7+1

The Rock Island (Armscor) Tac Ultra Compact is a compact 1911-pattern semi-automatic handgun built on a steel frame with tactical features intended for everyday carry and range use. It ships with battle-ready G10 grips, a full-length accessory rail and a skeletonized hammer and trigger with an adjustable over-travel stop. For a slide-mounted red dot that pairs well without exceeding $1,000, consider a compact footprint optic such as the Trijicon RMR Type 2 for reliable dot acquisition and durability.

Common applications: everyday carry (EDC) and range training/target shooting.

The fiber optic front and adjustable rear sight provide a clear sight picture for deliberate shooting, while the skeletonized trigger and hammer contribute to a crisp trigger feel.

Its G10 grips and parkerized steel finish make it durable for frequent range use and carry. If you prioritize a compact, steel-frame 1911 with tactical options and traditional controls, this model delivers a straightforward, mechanically honest package.
