Rock Island Armory
The Rock Island Armory Rock Ultra CCO is a 1911-style 45 ACP pistol built for shooters who want a reliable, no-nonsense service sidearm at a practical price point. This single-action 45 delivers proven stopping power with a 4.25-inch barrel and 7+1 capacity, making it suitable for duty carry, home defense, or range work. The Parkerized finish provides durable corrosion resistance, while the Series 70 type firing system keeps the design simple and maintainable—exactly what working shooters have trusted for decades.
Ergonomics matter on a fighting gun, and the Rock Ultra CCO addresses that with an ambidextrous thumb safety featuring a high sweep grip that's fast and intuitive from either hand. The skeletonized trigger reduces creep and weight for better shot placement, and the full-length guide rod adds stability and durability to the platform. For a gun in this category, these refinements show Rock Island Armory wasn't cutting corners on the fundamentals.
Sights are equally practical: a fiber optic front sight for fast target acquisition in varied light, paired with tactical-style adjustable rear sights so you can dial in your point of aim. The combat hammer provides a clean break without sacrificing reliability. Whether you're looking for a straightforward 1911 for concealed carry, truck duty, or the range, this Rock Island delivers the features serious shooters expect without the premium price tag of boutique custom guns.
| Caliber | 45 ACP |
| Barrel Length | 4.25 inches |
| Capacity | 7+1 (magazine + chamber) |
| Action Type | Single Action |
| Finish | Parkerized |

Yes. The Rock Ultra CCO's 4.25-inch barrel and 7+1 capacity make it a practical size for belt carry or patrol work. The ambidextrous safety and adjustable sights support reliable operation in either role.
Rock Island Armory focuses on delivering core 1911 features—a Series 70 firing system, full-length guide rod, and combat-proven ergonomics—without premium pricing. You get a functional, durable .45 without paying for custom work or exotic finishes.
The Rock Ultra CCO is a standard 1911 platform, so it is compatible with common 45 ACP 1911 magazines and many aftermarket parts, though we recommend confirming fit with your specific accessories.
The fiber optic front sight gathers ambient light for faster target pickup in daylight and low-light conditions. The adjustable tactical rear sight lets you dial in elevation and windage to match your ammunition and intended distance.
