Rock Island Armory TCM Standard FS 22 TCM 5in Black Parkerized Pistol – 10+1 Rounds – The TCM Rock Standard is constructed in 4140 Ordanance steel and refined by Rock Island’s carefully managed hand fitting process. Built to drive the original Armscor 22 TCM cartridge over 2000fps, it features a 5in barrel with penetrating impact and remarkably light recoil. Add a double stack mag well with 10-round capacity and it earns respect for delivering a constant high-velocity payload. Includes skeltonized hammer and trigger with adjustable over travel stop and low-profile anti-snag front and rear sights. This pistol is fitted with checkered polymer grips and finished with a durable parkerized coating.
