captive bolt pistol

a handheld weapon used for euthanasia of large animals. The muzzle is placed against the subject's forehead. When the trigger is pulled, or the firing pin struck a sharp blow, a 3 cm rod, 1 cm diameter exits sharply from the muzzle and pierces the skull and damages the brain. The rod does not leave the weapon and there is no possible risk of injuring a bystander.
