In the first parts of the movie, Ordell Robbie (Samuel L. Jackson) shows a pre-recorded TV presentation of "Chicks Who Love Guns" to Louis Gara (Robert De Niro) being played on a TV.
The show features 5 guns in the following order :
TEC-DC9
A TEC-DC9 can be seen in the hands of Sidney. The information claims the gun uses a 32 round "clip" instead of the proper term "magazine". When firing the gun, she's pretty much shooting the ground yet everything she aims at is destroyed.
Steyr AUG
A Steyr AUG-A1 can be seen in the hands of Cindy. She refers to it as an "Aug" instead of A-U-G. (Ordell also mispronounces "Steyr")
AKM
An AKM rifle (referred to incorrectly as the "Chinese model") can be seen.
Beretta PM12S
A Beretta PM12S can be seen in the hands of Britanny, although it is referred to as the older M12S model.
Mossberg 500
The final chick Tammy Jo uses a Mossberg 500 with a skeletal stock and a heat shield in the video, and accidentally shoots the camera man with it. She claims the gun has a "standard choke" barrel, but it isn't fitted with a choke. Note that this chick doesnt appear in the actual movie.
In the film itself, Max Cherry (Robert Forster) opens his gun cabinet and retrieves a "stun gun". A Mossberg can be seen in the cabinet as well as some other shotguns.
Mossberg 500 Sawed Off
In the actual film, Ordell Robbie (Samuel L. Jackson) bends down into the trunk of a car and pulls out a sawed off Mossberg 500 pump action shotgun with ventilated barrel ribbing that Beaumont Livingston (Chris Tucker) shall use for a job in Koreatown - at least he's told so. Beaumont reluctantly takes it and lays in the trunk.
Smith & Wesson Model 10
Ordell (Samuel L. Jackson) pulls a Smith & Wesson Model 10 out of his glove compartment to kill Beaumont. The script's description of the scene: "Inside the Oldsmobile, Ordell reaches into the glovebox and pulls out a five-shot .38 snubby."
Smith & Wesson 5906
ATF Agent Ray Nicolette (Michael Keaton) keeps his Smith & Wesson 5906 in both a shoulder holster and a belt holster, drawing and firing it during the confrontation in Cherry's office.
Colt Detective Special
When Max Cherry (Robert Forster) picks up Jackie Brown from jail, he had to leave his Colt Detective Special at the entrance. He later returns it back into his glovebox in his car where Jackie Brown (Pam Grier) discovers it while checking for cigarettes inside. Without Max knowing it, she "borrows" it for later use and gives it back to Max the next day. In the final scene of the movie in Max's office, she again gets a grip on it as it is deposited in a drawer of Max's desk.
Beretta Jetfire
Ordell (Samuel L. Jackson) takes a nickel Beretta Jetfire from his car when he goes to confront Jackie Brown (Pam Grier) after Cherry drives her home. Jackie takes it from Ordell after disarming him and presumably keeps it as she tells Cherry the next day she has her own gun.
Interesting to note that the script names the weapon as a "little Targa .22 pistol."
Glock 19
Det. Mark Dargus (Michael Bowen) carries a Glock 19 in a shoulder holster, drawing it at the end.
Louis Gara (Robert De Niro) draws and fires his nickel M1911A1 twice in the mall parking lot. Ordell (Samuel L. Jackson) later takes it from him and uses it throughout the rest of the film. The script had called for Gara to be armed with a Beretta 92FS instead.
