Rock Island Rock Ultra FS 51719 | .40 S&W | 5″ Barrel

The Rock Island Armory Rock Ultra FS (MFG# 51719) is a full-size 1911-pattern pistol built on a steel frame with a parkerized finish and G10 tactical grips. It is configured as an 8-round single-stack semi-automatic with a full-length guide rod, adjustable rear sight and a high-visibility fiber-optic front sight. This configuration suits target and range use as well as competition where a full-size 1911 platform is preferred. A compact red-dot such as a Holosun 507C or a Trijicon RMR would be an appropriate optic choice that pairs well with this pistol while remaining under $1,000.

The parkerized finish is utilitarian and durable for regular range use.

Owners commonly praise the model for its strong perceived value and a crisp factory trigger pull that is ready to use out of the box. These attributes make the Rock Ultra FS a practical choice for shooters seeking a traditional 1911 experience on a budget.
