Colt Mk IV Gold Cup National Match Enhanced
After trying out several guns in the desert, Carol McCoy (Kim Basinger) picks out a Colt Gold Cup National Match Enhanced for herself. Doc initially refuses, as it's his gun, but she is seen using it through the duration of the film.
Walther PPK/S
Carol McCoy (Kim Basinger) tries out a Walther PPK/S in the desert but doesn't like it, complaining to Doc that the ".380 is too small." Like the SIG, it is never seen again in the film.
Colt Python
Rudy Travis (Michael Madsen) carries a Colt Python revolver, as the Rudy in the original did. In this version, however, the Python has a much shorter barrel and is nickel plated. Fran (Jennifer Tilly) briefly handles it while her and Rudy are staying at the Border Hotel. After knocking out Rudy, Doc takes his revolver from him.
Browning Hi-Power
Frank Hansen (Philip Seymour Hoffman) uses a Browning Hi-Power during the dog track robbery, most notably seen when he hijacks the truck driver and shoots the guard.
The guard at the dog track tries to draw a Smith & Wesson Model 38 "Bodyguard" from an ankle holster, causing Frank to shoot him several times. Frank picks up the gun and unloads it to show Doc and Rudy why he shot the guard.

Benyon's main thug, Jim Deer Jackson (David Morse) draws a nickel Desert Eagle when he spots Carol through a hotel window.
Beretta 92 Centurion
One of Benyon's thugs in the hotel carries a Beretta 92 Centurion, which Doc disarms him of and tells the thug to run away. This looks like a Centurion because of the shortened barrel (See Second Photo)
