The term 'SCARFACE GUN' is a reference to the 1983 film Scarface, which starred Al Pacino as Tony Montana, a Cuban refugee who rises to power in Miami's drug underworld. The gun used by Montana in the movie is an UZI, a type of submachine gun developed in Israel in the 1950s. The UZI is a popular weapon among military and law enforcement personnel, as well as criminals, due to its compact size and high rate of fire.
