 The Deer gun was made of cast aluminium, with the receiver formed into a cylinder at the top of the weapon.The striker protruded from the rear of the receiver and was cocked in order to fire, and a plastic clip was placed there to prevent an accidental discharge, as the Deer gun had no mechanical safety.The grip had raised checkering, was hollow, and had space for three 9 mm rounds and a rod for clearing the barrel of spent cases.
