Pistol-whipping (also known as buffaloing) is the act of using a handgun as a blunt weapon, wielding it as if it were a club or blackjack.[1] "Pistol-whipping" and "to pistol-whip" were reported as "new words" of American speech in 1955, with cited usages from 1940s.[2] However both the term and the practice trace back to the Wild West of the 19th century.
Paul Wellman notes that clubbing an opponent with the butt of a gun held by its barrel, seen in some westerns, has its problems. There are several reasons why it would be wrong. One of which is that the gun would be rendered useless for its primary purpose which is to fire a projectile out of the barrel. There is also the danger of an unintentional discharge which could fatally wound the "clubber". Plus there would also be a loss of precious time to switch from holding the barrel to holding the grip in the standard shooting way.
Instead, pistol whipping was done with the long and heavy barrel of the gun held in an ordinary manner, thus removing the issues involved with holding the gun by the barrel.[3][4] This form of pistol-whipping with an 1860s style revolver was tested on the Spike TV television show Deadliest Warrior.[5] The testers showed that a whip using the long barrel of a Colt revolver produced enough force to fracture a skull and could potentially kill a man in a single blow.
In modern times, pistols are much more compact generally only extending around four inches past the trigger, making a modern pistol much less suitable for this style of pistol whipping than their predecessors. Because of this, pistol whipping is mainly performed by hitting a person with the base of the grip while still holding it normally, striking in a downwards motion. This adds the weight of the gun to the force of the blow and uses the metal frame (rather than the barrel) as the point of impact, but deprives the blow of the leverage provided by barrel length.
Pistol whipping may leave unusual lacerations on the body of the injured due to various protruding details of the pistol.[6] Semicircular or triangular lacerations on the skin may be produced by the butt of a pistol. The magazine well and the base of the magazine produce rectangular lacerations on the skin.[7] These lacerations can vary in depth and severity, but if "whipped", fractures are common.
Pistol-whipping should not be confused with buttstroking, a close combat military discipline.
