• Armscor’s TCM series of pistols are functionally a 1911 series-70 pistol design but chambered for their unique .22 TCM cartridge. Since the .22 TCM is essentially a stepped-down 9mm cartridge, the gun can fire 9mm rounds from the same magazine by simply replacing the barrel and recoil spring. Armscor ships both .22 TCM and 9mm barrels and springs with each TCM pistol. The TCM series includes both single-stack 10-round models and double-stack 17-round models.
