Glock 17 pistols are used by Sheriff Stan Watkins (Michael Bowen), Dep. Rolston (Eric Breker), as well as Chris Vaughn (Dwayne "The Rock" Johnson) when he becomes Sheriff of the town. When Watkins and some other of the deputies shoot up the police station, Chris gives his Glock to Deni (Ashley Scott), who helps distract Watkins at one point, but does little more than waste ammo.
Chris Vaughn (Dwayne "The Rock" Johnson) keeps a Remington 870 locked up in his shed. He takes it with him to assault the casino but then decides to instead take a 4"x4" block of wood instead. He gives the 870 to his father, Chris Vaughn Sr. (John Beasley), who declines claiming he put his guns up long ago. Later in the film when the ex-security guards attack Chris' family, Vaughn Sr. changes his mind, takes the 870 and kills the last man with it.
Booth (Kevin Durand), one of the guards in the Casino tries to shoot Chris with a Mossberg 500 before being dispatched by him and his block of wood. Later in the film when both Chris and Ray Templeton (Johnny Knoxville) are officers, they are both seen using Mossberg 500 shotguns throughout the film.
One of the security guards in the casino draws a Beretta 92FS when Chris starts a fight for catching a cheating Craps dealer use weighted dice. The same guard uses the Beretta when attacking Chris' family later in the film.
One of the guards in the casino wields a sawed-off Ithaca 37 shotgun when Chris assaults the place. Another guard is seen using the M37 when they attack Chris' family.
Daewoo K3 (visually modified to resemble FN Minimi SPW)
While Chris and Deni are in the Sheriff's Department, Stan Watkins and another deputy begin firing at them with Daewoo K3 LMGs that have been modified to resemble the FN Minimi SPWs("Special Purpose Weapons").
While Chris and Deni are in the Sheriff's Department, one of the ex-deputies (Ty Olsson) open up with an Colt Model 715, the earlier Colt Canada C7 produced by the American Colt to serve Canadian forces, noted by M16A2 forward assist and shell deflector with M16A1 style sights. It is fitted with a 100 round Beta-C magazine.
Note: Since the film was 100% filmed in British Columbia, it is expected that the armorers were Canadian. The Armorer, Ron Blecker, though a trained American Soldier is a common face on Canadian television, seen as a background soldier (and military tech advisor) on Canadian shot shows like Battlestar Galactica and Stargate: SG1. Blecker's crew and group are based out of Canada and get all their weapons from Canadian sources.
One of the Ex-Security guards in Chris' house is armed with an M1911A1 pistol which he manages to hit Ray in the leg with before he stabs him with a potato peeler. He later is shown to still be alive and is shot by Chris Sr. with the 870 shotgun.
