The Rock Island 1911 Rock Ultra CS-L Combo pistol in dual-caliber 9mm and .22 TCM9R (brand part no. 56633) ships with barrels for both chamberings, letting shooters swap between mild rimfire-adjacent .22 TCM9R practice and standard 9mm defense or carry use. Armscor/Rock Island Armory builds the pistol on a black hardcoat-anodized frame with a black Parkerized slide, and an MPS1 adjustable rear sight pairs with a fiber optic front for precise aiming. G10 grips and a manual thumb-and-grip safety combination round out the controls, with an 8+1 capacity single-action trigger.
