Demolition Man is a 1993 action movie starring Sylvester Stallone as John Spartan, a Los Angeles cop known for his destructive reputation who is found guilty of a crime he didn't commit and is sentenced to be frozen in a cryogenic prison along with his nemesis Simon Phoenix (Wesley Snipes). When Phoenix escapes from the prison in the future world of San Angeles, Spartan is then unfrozen and asked to use his old school tactics to take down his archenemy.
The following weapons were used in the movie Demolition Man:
During the 1996 prologue, LAPD officer John Spartan (Sylvester Stallone), aka "The Demolition Man", carries only a Beretta 92FS as he jumps from an LAPD helicopter onto the roof of the building Simon Phoenix (Wesley Snipes) is holed up in. He also later uses one in his battle with Phoenix in the cryo prison.
Beretta 92FS Inox
In the future world of San Angeles, Spartan uses a Beretta 92FS Inox, as identified by its slide-mounted safety, as his main sidearm. He uses it most notably to shoot up the display screens and one of the ticket-dispensing machines in Dr. Raymond Cocteau's (Nigel Hawthorne) office.
IMI Desert Eagle Mark VII
Among the weapons used by the people living in the San Angeles sewer system is a IMI Desert Eagle.
Used by Phoenix very briefly near the end of the film.
Submachine Guns
Cobray M11/9
A Cobray M11/9 is among the weapons procured by Phoenix from the museum. It is later used by Phoenix to shoot at Spartan during the final scene in the cryo-lab.
IMI Uzi
A IMI Uzi is among the firearms on display in the museum's armory.
Heckler & Koch MP5K
A Heckler & Koch MP5K is used by one of Phoenix's men at the beginning of the film. Phoenix also acquires a number of MP5Ks from the museum armory in 2032, which are used by henchmen, as well as Phoenix himself.
The MP5K used by Phoenix in the museum shootout is fitted with a PDW folding stock to emulate an MP5K-PDW (though it is not a genuine MP5K-PDW, as evidenced by the lack of an extended barrel and Navy trigger group).
Heckler & Koch MP5A2
A MP5A2 is seen used briefly during the fight at the museum.
Shotguns
Remington Spartan Sawed-off Double Barrel Shotgun
The double barreled shotgun that John Spartan takes out of the display case is the Remington Spartan.
Heckler & Koch G11 (mocked up as a particle beam gun)
During the museum shootout, Phoenix wonders: "Wait a minute, this is the future. Where are all the phaser guns?" So he finds a futuristic particle Beam gun which in actuality is a Heckler & Koch G11.
Ruger AC556F
An AC556F is used by one of Phoenix's new gang members in the fight in the sewers.
Norinco Type 56-1
The Chinese Norinco Type 56-1 is used by Phoenix and his future gang at many points in the movie, most notably to execute all the workers in the cryoprison.
Machine Guns
M60
An M60 is briefly seen mounted near a window of the building Spartan goes into to find Phoenix at the beginning.
Other
Double Barrelled Flare Pistol
Edgar Friendly (Denis Leary) is seen using a double barrelled pistol as his weapon of choice. According to Long Mountain Outfitters, the weapon is a Japanese double-barreled flare pistol, possibly a 28mm Kayaba Type 90, adopted by Japanese Imperial Navy in 1930.
The Armory
In addition to the already mentioned weapons, numerous other handguns, rifles and machine guns are featured in the armory of the Hall of Violence.
