The Rock Island TCM Standard pistol in .22 TCM with a PECVD coating and 17-round capacity (brand part no. 56878) is a high-capacity 1911-pattern handgun built around Armscor’s high-velocity .22 TCM chambering. Armscor/Rock Island Armory constructs the frame from steel with a parkerized finish and polymer grips, and the 4.3-inch barrel pairs with adjustable sights combining a fixed fiber-optic front with an adjustable rear. A skeletonized hammer, beavertail grip safety, and GI-style trigger round out the classic 1911 control layout. Among high-capacity semi-auto handguns, this TCM Standard configuration favors shooters who want unusually high capacity in a 1911-pattern pistol.
