blowback

1. Escape, to the rear and under pressure, of gases formed during the firing of the weapon. Blowback may be caused by a defective breech mechanism, a ruptured cartridge case, or a faulty primer.
2. Type of weapon operation in which the force of expanding gases acting to the rear against the face of the bolt furnishes all the energy required to initiate the complete cycle of operation. A weapon which employs this method of operation is characterized by the absence of any breech-lock or bolt-lock mechanism.

Blowbacks are limited to smaller-caliber, less powerful pistols because the slide/bolt needs to be sufficiently heavy to balance the pressure generated by the cartridge to keep the mechanism from opening fully before the bullet exits the muzzle and the pressure can drop to a safe level (to prevent the shooter from getting a faceful of hot gas and powder residue).
