Rock Island Armory's 1911: From 9mm to .22TCM
This video showcases the Rock Island Armory 1911's unique ability to switch between 9mm Luger and the .22 TCM cartridge. The demonstration highlights the ease of conversion, with the pistol being shipped as a 9mm and including a .22 TCM barrel for easy swapping. The .22 TCM is noted for its high velocity (2,000 feet per second) with a light 40-grain projectile, resulting in very low recoil.
