The majority of the Ruggsville Sheriff Deputies carry the Smith & Wesson Model 10HB. Mother Firefly (Leslie Easterbrook) uses a Model 10HB and a Trooper MkIII in the raid, and Otis B. Driftwood (Bill Moseley) uses a Model 10HB later in the film. Also bounty hunter Rondo (Danny Trejo) carries one.
Smith & Wesson Model 15
Captain Spaulding (Sid Haig) carries a Smith & Wesson Model 15 in a shoulder holster, and also has one pointed at his face in his prostitute dream sequence. During the raid on the house a Sheriffs deputy is seen using one.
Colt Trooper
The Colt Trooper MK III appears in the film. During the raid on the house Mother Firefly use a Trooper MkIII and a Smith and Wesson Model 10. The MkIII is used by Baby (Sheri Moon Zombie) in the end shootout sequence.
Colt Lawman
Sheriff Wydell (William Forsythe) uses a .357 magnum Colt Lawman MkIII as his sidearm. It is identifiable by not having a shrouded ejector rod, and by its sights.
M1911A1
Several members of the Firefly Family use M1911A1 pistols. Most notable Otis (Bill Moseley) and Baby (Sheri Moon Zombie). At one point when Otis is knocked over the head with a branch he drops his 1911A1. The grips look like Colt Series 70 grips (Wydell's police buddy has the same grips), but the pistol itself has a laynard ring which would mean its not a Series 70. It is most likely a MGC M1911A1 replica pistol. A surpressed 1911A1 is used by a bounty hunter to kill Otis's hooker.
Remington 1100
Wydell County Sheriff's Deputies and the Sheriff especially use the Remington 1100 Semi-automatic Shotgun against the Rejects. Spaulding also uses the Remington 1100 during the final shootout.
Remington 870
During the raid scene Baby (Sheri Moon Zombie) uses a Remington 870 with the stock sawed off. A few deputys also use a 870 during the raid and final shootout. One of Charlie's men carries an 870 with him.
Mossberg 500
The Mossberg 500 shotgun appears in the film. Charlie (Ken Foree) pulls one on Otis, Spaulding, and Baby when they first arrive at the ranch. It turns out to have a hose hooked to it that squirts water.
M16-A1
The M16A1 is used by some of the Wydell County Sheriff's Deputies and Otis in the raid shootout and the final fight.
BAR 1918
In the opening gun battle Rufus (Tyler Mane) in all his homemade armor glory uses a Browning Automatic Rifle against the Sheriffs department.
In Wydell's office is a gun rack with several differant firearms on it. The first two weapons from the top are rifles that appear to be lever actions. The thrid is a pump action shotgun possible a Winchester Model 1200/1300. The bottom weapon has a odd looking hooded sight and might just be a bb gun put there to look like a rifle.
