An expansion to its proprietary .22 TCM line of ammunition, Armscor has introduced the .22 TCM 9R cartridge—a modified design that matches the overall cartridge length of 9 mm Luger, thus opening the way for firearm conversion kits. To make good on that goal, Rock Island Armory has introduced a Glock conversion kit for the .22 TCM 9R. By using the Rock Island slide assembly, a Glock 17 or 19 (Gens 1, 2 and 3) can be quickly converted to fire the .22-cal., high-velocity round.
