Rock Island Armory Rock Ultra CCO .45 ACP 7+1

The Rock Island Armory Rock Ultra CCO is a 1911-style, single-action semi-automatic pistol chambered in .45 ACP, designed to reduce grip length while preserving shootability and classic 1911 handling. Manufactured by Rock Island Armory, this CCO (Compact Carry Officer) configuration pairs an officer-size grip frame with a commander-length slide for a balanced concealed-carry and range-ready handgun.

The Rock Ultra CCO addresses a common 1911 carry concern: grip length. By shortening the grip profile, the pistol improves concealability without sacrificing the slide length and sight radius that aid recoil management and follow-up shots. Shooters retain the familiar single-action trigger, frame-mounted safety, and ergonomics that define the 1911 platform, while benefiting from a more compact footprint suitable for daily carry or duty use.

Intended for concealed carry, duty/patrol roles, and regular range shooting, the Rock Ultra CCO offers a practical middle ground between full-size and compact 1911 pistols. Its steel construction adds weight for recoil control with .45 ACP, while modern sighting and grip components support fast target acquisition and consistent handling.
