Saw is a 2004 American horror film starring Cary Elwes as Dr. Lawrence Gordon and Leigh Whannell as Adam Faulkner-Stanheight. The film was directed by James Wan and written by Leigh Whannell. It is the first installment in the Saw franchise (despite the fact that exists a short film with the same name, directed and starred by Leigh Whannell). The plot focuses on two men who awake to find themselves chained in a large dilapidated bathroom, with one being ordered to kill the other or his family will die. At the same time, the police, led by a detective David Tapp (Danny Glover), investigate a series of gruesome murders. All this is the plan of a serial killer, nicknamed Jigsaw, who has his own philosophy explaining all his actions. He believes that one who does not value life is not worthy of it. A sequel, titled Saw II, was released in 2005.
The following weapons were used in the film Saw:
A Beretta 92FS is used by Detective Tapp (Danny Glover) after his dismissal (this is most likely his personal weapon). He loads the magazine after hearing gunfire in Gordon's apartment and runs there. He uses the gun during the gunfight with Zep Hindle (Michael Emerson) and later when he pursues Zep through the sewers.
Beretta 92FS Inox
Detective Sing (Ken Leung) carries a Beretta 92FS Inox as his sidearm during th flashback in which he and Detective Tapp (Danny Glover) break into Jigsaw's (Tobin Bell) warehouse, and uses it to disable one of the "Drill Chair" traps to save Jeff Ridenhour (Ned Bellamy).
Smith & Wesson Model 686
A Smith & Wesson Model 686 is found lying on the floor next to the dead body (Tobin Bell) in the room. An unknown person through a Panasonic RN305 recorder explains Lawrence Gordon's (Cary Elwes) task: he has to kill Adam if he wants to see his family again. A little later, Gordon finds a bullet in his pocket. When Lawrence's nerves are running out, he inserts a cartridge into the cylinder and shoots Adam in the shoulder. When the game ends, the gun remains in the bathroom.
Wilson Combat "Protector"
A two-tone Wilson Combat "Protector" is used by Zep Hindle (Michael Emerson) for holding Gordon's family hostage and in the gunfight with Detective Tapp. It is also briefly used by Alison Gordon (Monica Potter) when she grabs it during a fight with Zep. Adam (Leigh Whannell) briefly picks it up after killing Zep in the final act and tries point it at Jigsaw but gets shocked by a remote and drops it. Like Gordon's revolver, the "Protector" stays in the bathroom after the events of the film.
12 Gauge Double Barreled Shotguns
While pursuing Jigsaw (Tobin Bell), Detective Sing (Ken Leung) is killed when he steps on a trip wire that is connected to four loaded 12 Gauge Double Barreled Shotguns that are mounted on the archway above him.
Ithaca 37 Deer Slayer Police Special
During the warehouse flashback, an Ithaca 37 Deer Slayer Police Special is used by both Detective Tapp (Danny Glover) and then by Detective Sing (Ken Leung) who both hold it on Jigsaw (Tobin Bell) before he escapes. After Tapp is wounded, Sing pursues Jigsaw with the Ithaca, and manages to shoot him in the back with it, before he is killed by a shotgun trip-wire trap.
When the camera zooms in on one of the shotgun's triggers, the shotgun turns into a Winchester 1300 due a continuity error.
