The origonal firearm capable of firing this round, the Colt 1911A1, was designed by the Colt Firearms Company in 1911. Due to the weapon's high-power, which is more powerful than a 9 milimeter round, the .45 calibur bullet is able to stop a potential assailant. Due to this capability, the weapons calibur has become quite popluar with law-enforcment, security, and even Military groups.
