The TCM from Rock Island Armory is two guns in one. With just a swap of the barrel, go from a 9mm to 22 TCM rounds. The 22 TCM cartridges from Rock Island Armory make it a longer-shooting pistol. The tech grid and adjustable rear sight mean the TCM is more than desirable – Fire it once, and you’ll be hooked.
