The Rock Island Armory Rock Ultra CS-L is a 1911-style compact pistol available in both 9mm and 22 TCM9R, built around a 3.6″ barrel and alloy frame. It ships with one 8-round magazine, G10 grips, a fiber optic front sight, and an adjustable LPA MPS1 rear sight. The lightweight aluminum frame maintains the power and durability associated with full-size 1911 designs while reducing overall weight, and the 3.62″ barrel delivers penetrating impact with notably light recoil. The single-stack magwell accommodates 8 rounds, while the pistol features a skeletonized hammer and trigger with adjustable over travel stop, battle-ready G10 grips, and a durable parkerized coating with black oxide frame finish.
This combo package includes a drop-in 22 TCM9R accessory barrel designed to fire original Armscor 22 TCM 9R cartridges, giving shooters access to expanded ammunition options. The dovetail-mounted fiber optic front sight works in tandem with the LPA MPS1-type adjustable rear sight, and the trigger breaks at 4 to 6 pounds. Measuring 7.38 inches overall, the compact profile is well-suited for concealed carry, sport shooting, or personal protection in a traditional 1911 platform with dual-caliber capability and modern features.
