Rock Island Rock Ultra CS 1911 | .45 ACP | 7 rd | MFG# 51479

The Rock Island Armory Rock Ultra CS is a compact 1911-style pistol offered by Armscor/Rock Island Armory. Chambered for .45 ACP, it combines a parkerized steel frame and slide with G10 tactical grips and upgraded sights for practical carry and range use. For a red-dot option under $1,000 that pairs well with this platform, consider a compact micro red dot such as the Holosun 507 series for fast target acquisition on a small 1911 slide. Useful applications include everyday carry where a full-size 1911 is impractical and precision practice or range work to maintain familiar 1911 ergonomics.
