- Recoil Operated
A form of locked-breech semi-automatic operation in which the barrel and breech remain locked together during the peak pressure, then move rearward under recoil to effect unlocking. Most high-power pistols use this system. Recoil operation is an operating mechanism used in locked-breech, autoloading firearms. As the name implies, these actions use the force of recoil to provide energy to cycle the action. In a recoil-operated handgun the barrel moves a short distance with the slide when the gun is fired and the bullet is still in the barrel. Other operating systems are Blow forward operated, blowback operated, gas operated, and chain.
