When fired, the recoil impulse from the ignited cartridge drives the barrel and slide back, locked together until the bullet leaves the barrel and pressures drop to a safe level. The cold-hammer-forged conventional rifled barrel is locked to the slide by means of a single rectangular lug around the barrel chamber that recesses into the ejection port in the slide.
