The Rock Island Rock Ultra CCO: Concealment Meets Capability
The Rock Ultra CCO represents a thoughtful approach to the classic 1911 platform, specifically engineered for shooters who demand both concealability and shootability.
Design Philosophy
This pistol combines an Officer-length grip frame with a Commander-length slide—a proven formula that balances the reduced printing profile of a compact carry gun with the sight radius and handling characteristics serious shooters expect. The shorter grip minimizes the chance of your firearm printing under a cover garment, while the longer slide provides better sight radius and a more substantial sight picture.
Mechanical Excellence
- Barrel: 4.25" button-rifled barrel supported by a full-length guide rod for consistent lockup and reliability
- Sights: Fiber optic front sight paired with an LPA MPS1-type adjustable rear sight for precise aiming in varied light conditions
- Trigger Control: Skeletonized hammer and trigger reduce weight and improve responsiveness; adjustable overtravel stop allows you to fine-tune break characteristics
- Grips: G10 tactical grips provide secure purchase in wet or gloved conditions
Finish and Build Quality
Parkerized steel slide combined with anodized aluminum frame creates a durable, corrosion-resistant platform. The beavertail grip safety ensures safe handling during presentation and reholstering.
The Rock Ultra CCO is a battle-ready 1911 that doesn't compromise on the fundamentals.
