History
Developed by Fred Craig and Armscor (Philippines) around 2010, introduced commercially in 2012. The .22 TCM uses a necked-down 9mm Luger case to fire a .22-caliber bullet at high velocity. The Rock Island Armory 1911 chambered for it includes a spare 9mm barrel, allowing the owner to switch between calibers with just a barrel swap. The TCM9R variant uses a shorter case and fires from standard 9mm magazines without modification. Gaining traction in the Philippines and among US 1911 enthusiasts.
