The TCM Rock Ultra FS is constructed in classic 70 series design and is refined by our carefully managed hand fitting process. Built to drive the factory original Rock Island 22 TCM cartridge at over 2000fps, it features a 5” barrel with penetrating impact and unprecedented light recoil. Includes skeletonized hammer and trigger with adjustable over travel stop, low-profile adjustable 2-dot LPA rear sight and high visibility fiber optic front sight. This pistol is fitted with battle ready G10 tactical grips and is finished with a durable parkerized coating. Add a drop-in 9mm accessory barrel and the TCM Rock Ultra offers the best in old and new with plenty of upgrades.
