Rock Island Armory Rock Ultra CCO 1911 | .45 ACP | 51857

The Rock Island Armory Rock Ultra CCO is a purpose-built 1911 variant intended for carry and range use, combining a commander-length slide with an officer-size grip. It ships with G10 tactical grips, a skeletonized trigger and hammer, and fiber optic front with an adjustable rear sight. For a red-dot option under $1,000 that pairs well with this platform, consider the Vortex Venom 3 MOA red dot for fast, reliable sight acquisition without overcutting the slide.

Typical applications for this pistol include concealed carry (CCW) where a compact grip helps reduce printing, and range-focused target shooting or competition where a crisp trigger and good sights improve accuracy.
