<p>A hand firearm such as a standard revolver having means for dispensing debilitating chemical substance through a nozzle (22) in the butt end, in a direction transverse to the barrel, whereby a self contained unit comprising a reservoir (15) for containing the debilitating chemical under pressure, such as Chemical Mace or tear gas, is detachably mounted on the butt end. A valve means (28) for dispensing the repellant is actuated by depression of a button (24) located on the detachably mounted butt end portion unit, below and out of the way of the hand grip, for operation by the last digit (25) of the hand. The presence of the reservoir (15) as the mounted butt end of the shank portion (14) of the gun allows for operation without interference with a strong hand grip, avoids accidental lethal firing of the weapon and permits fast recharging in the event the reservoir (15) is depleted or in the event that there is a mechanical failure of the discharge system (21, 22, 28). </p> |
