Face/Off is a 1997 action thriller directed by John Woo that stars John Travolta as an FBI agent who undergoes an experimental procedure to transplant the face of his arch nemesis (Nicolas Cage) onto his own body in order to go undercover to find a bomb planted within the city of Los Angeles.
The weapons of choice for Castor Troy (Nicolas Cage) are two gold titanium nitride-plated Springfield Armory M1911-A1 V-10s fitted with custom gold inlaid grips, that he keeps in two small-of-the-back holsters. Among the obvious modifications to the guns include skeletonized hammers, ball stirrup cuts on the slide, beavertail grip safeties, ambidextrous slide stop safeties, target sites, moderately beveled magazine wells, and V-10 ported slides/barrels. He uses them both during the first major gunfight of the movie, putting a hole in the windshield of the helicopter Sean Archer (John Travolta) is in and later gunning down several agents in the airport hangar. Later in the movie, when Archer has assumed Troy's identity and face, he is given these weapons by Dietrich (Nick Cassavetes). He then uses them for the proceeding gunfight as the police raid the building. These pistols tell you how much Castor Troy enjoys his job!
SIG-Sauer P226
Sean Archer (John Travolta) uses a SIG-Sauer P226 with a nickel slide as his sidearm in the film, which has been fitted with a set of Hogue rubber grips. When he and Castor Troy (Nicolas Cage) switch faces and identities, Troy/Archer begins using the weapon, killing Dietrich (Nick Cassavetes) and another FBI agent with it before he loses it during the funeral home's "Mexican Standoff".
Beretta 92FS
Prison guards on the oil drill platform keep Beretta 92FS pistols as their sidearm. When Sean Archer/Castor Troy (Nicolas Cage) escapes from the electroshock room, he takes a guards Beretta and uses it to fire on the guards, carefully placing his shots as not to kill them. During the final firefight Archer/Troy uses a pair of Berettas, wielding them akimbo as per the standard norm of John Woo films. Jamie (Dominique Swain) picks one of these up as Archer/Troy and Troy/Archer (John Travolta) struggle in the church's courtyard, only to be misled into shooting her father in the arm. Troy/Archer then picks the Beretta up and holds it on Jamie before she digs a kris-bladed butterfly knife into his leg, which he ironically gave her as a gift to protect herself.

SIG-Sauer P228
Agents during the shootout in the airport hangar are seen using SIG-Sauer P228 pistols as their sidearms.
During the final shootout in the church, Castor Troy's girlfriend Sasha Hassler (Gina Gershon) is armed with a Smith & Wesson 3913. She likely took it from one of Dietrich's (Nick Cassavetes) friends, who was killed while using it during the raid on his apartment.
Smith & Wesson Model 36
When Eve Archer (Joan Allen) goes to the hospital to test blood samples from Sean Archer/Castor Troy (Nicolas Cage) and Castor Troy/Sean Archer (John Travolta) to see if they are actually swapped, Archer/Troy confronts her. She then pulls a nickel plated Smith & Wesson Model 36 with a spurred hammer, which she claims she took from her "fake husband".
During the FBI raid on Dietrich's (Nick Cassavetes) apartment, one of Dietrich's thugs uses a nickel-plated Walther PPK to try and defend against the swarm of Law Enforcement officers.
Submachine Guns
Armscor BXP
During the final firefight in the funeral home one of Castor Troy/Sean Archer's (John Travolta) thugs, Leo (Tommy Flanagan) wields a South African Armscor BXP before being killed. Troy/Archer picks it up and fires it as he flees from Sean Archer/Castor Troy (Nicolas Cage) who is firing at him.

A Stechkin APS machine pistol is used briefly by one of Dietrich's (Nick Cassavetes) friends to fire on police raiding the apartment building. While in the courtyard of the funeral home, Castor Troy/Sean Archer (John Travolta) uses one briefly before having it knocked from his hand. At the conclusion of the fight, Sean Archer/Castor Troy (Nicolas Cage) picks the gun up and fires a long burst at Troy/Archer after he unsuccessfully tries to kill his daughter.

Colt Sporter II Carbine (mocked up as XM177)
Police patrolling the river fire Colt Sporter II carbines mocked up as XM177 Commando rifles by adding a mock muzzle break to them. Since the lowers have a full-auto selector switch (which the semi-auto Sporter II lower lacks), it is assumed that the guns are either converted semi auto lowers or fitted with GAU/A5 or M16A1 style lowers. Agent Loomis (Matt Ross) also uses one fitted with an M203 grenade launcher during the shootout at Dietrich's apartment.
Colt Sporter II Carbine
The FBI Agents in the film sometimes carry Colt Sporter II Carbine rifles, noted by their collapsing stocks, A1-style upper receivers, forward assists, and 16" barrels. They do not feature the large XM177 muzzle breaks.
Remington 700
Castor Troy (Nicolas Cage) uses a Remington 700 sniper rifle fitted with a suppressor, Harris bipod, and heavy stock and barrel to try and assassinate Sean Archer (John Travolta) while he rides the merry-go-round with his son Michael (Myles Jeffrey). The bullet passes through Sean's chest and fatally wounds Michael, leading to Archer's relentless pursuit of Troy in the film's story.
Ruger AC556
The prison guards on the oil drill platform are armed with Ruger AC556 assault rifles, as noted by their flash suppressors and bayonet lugs. During the prison break scene, Ivan Dubov (Chris Bauer), the inmate that helps Archer/Troy (Nicolas Cage) escape from the electro-shock chamber, picks up an AC556 rifle from one of the dead guards and kills several guards before Archer/Troy stops him.
Shotguns
