The .22 TCM, short for Tuason Craig Magnum, is a proprietary cartridge developed by Fred Craig and Rock Island Armory.[2]

It is based on the .223 Remington case, shortened so that the overall length is slightly longer than that of a 9x19mm cartridge. The cartridge feeds from a standard 9mm magazine.[3]
