Django Unchained is a 2012 "Southern" (as the film has elements of the Western, but takes place primarily in the southern United States of 1858) that was written and directed by Quentin Tarantino. The film stars Jamie Foxx as Django Freeman, a slave who is liberated by a bounty hunter named Dr. King Shultz (Christoph Waltz) in order to track down and eliminate the notorious Bittle Brothers of whom Shultz has no knowledge of appearance. If the brothers are brought to justice, Shultz promises to aid Django in his quest to find the man who has enslaved his wife and rescue her from his clutches. The cast includes Leonardo DiCaprio, Don Johnson, Walton Goggins, and Samuel L. Jackson. The film's name is a homage to the 1966 Italian Western Django that starred Franco Nero (who also has a role in this film). According to IMDb.com, the armorers for the film are Tony Didio, Jr. and gunsmith Larry Zanoff.
The following weapons were used in the film Django Unchained:
Dr. King Schultz (Christoph Waltz) and Django (Jamie Foxx) use Cobra "Big Bore" Derringers as their secondary weapons. They are attached to drawer slides that allow for quick pistol drawing. They are both polished steel with pearl grips which means they are duplicates or in fact the same pistol. Since the film takes place in 1858, the use of a Derringer would be anachronistic (as they did not become popular until well after the Civil War). The Cobra "Big Bore" Derringer seen in the film is a modern version of the Remington derringer.
The Sheriff's model of the Remington 1858 appears to be the revolver carried by Django throughout much of the film. A nickel (or stainless repro) version is carried by Billy Crash (Walton Goggins).
Lil' Raj Brittle (Cooper Huckabee) fumbles with a third model Colt Dragoon during a confrontation with Django.
Django himself then takes it from him and is seen using it.
Shotguns
Double Barrelled Muzzle-loading Shotgun
A double barrelled muzzle loading shotgun is first seen in the hands of slavers Ace Speck (James Remar) and Dicky Speck (James Russo). Dr. King Schultz (Christoph Waltz) and a slave then use the shotgun. Sheriff Bill Sharp (Don Stroud) also carries the shotgun when confronting Schultz. Calvin's bodyguard, Butch Pooch (also James Remar) uses a short-barreled muzzle-loading Double Barrel Shotgun.
Rifles
Sharps 1874 Buffalo
A Sharps 1874 Buffalo appears to be the rifle used by both Schultz and Django. The Sharps Buffalo wasn't introduced until twenty years after the film's time period.
Henry 1860
A steel framed Henry 1860 rifle can be seen being used by henchmen, Django (Jamie Foxx) and Dr. King Schultz (Christoph Waltz). This weapon is anachronistic due to the movie taking place in 1858, although they could be intended to be stand-ins for the Volcanic Repeater rifles which were the immediate predecessor to the Henry rifle.
Spencer 1860 Saddle Ring Carbine
The Spencer 1860 Carbine also appears to be carried by some of the men employed by Spencer 'Big Daddy' Bennett (Don Johnson). The Spencer wasn't introduced until two years after the film's time period.
