The Rock Island Armory 1911 Rock Ultra CS-L Combo is a lightweight 9mm 1911 that ships with a 22TCM9R accessory barrel (Rock Island Armory part no. 56633). Rock Island Armory gives the CS-L an aluminum frame for a lighter feel than the steel Rock Ultra CS, a beveled single-stack magwell and an 8-round magazine. Dovetail-mounted fiber optic front and MPS1-type adjustable rear sights, G10 grips, a skeletonized hammer and a 4- to 6-pound trigger with an adjustable overtravel stop make it a well-balanced pistol for target shooters. The included 22TCM9R barrel expands the load options for the 9mm platform.
