Wounds caused by tight contact with the barrel-cylinder gap of revolvers

A case is presented in which the recognition of a tight cylinder gap contact wound was crucial. Experiments were carried out to reproduce the wound which was noted on the hand of a robbery suspect. Tight contact with the cylinder gap of a revolver produces a characteristic, readily recognizable wound. It is characterized by an L-shaped pattern of powder residue. Along one axis a searing burn may occur which may be deep and which may lead to significant tissue destruction.
