Samurai Cop is a 1991 direct-to-video action film directed, produced and written by Amir Shervan and stars Matthew Karedas (credited as Matt Hannon) as the titular "Samurai Cop" - a police officer from San Diego, trained by the masters in Japan - who battles a Katana gang within Los Angeles. It also starts Robert Z'Dar, Gerald Okamura, and Mark Frazer. The film has since attained a cult following, but is often cited as one of the worst films of all time. Nearly 25 years later, the sequel Samurai Cop 2: Deadly Vengeance was released in 2015.
The following weapons were used in the film Samurai Cop:
Officer Joe Marshall, aka the "Samurai Cop" (Matt Hannon), carries an early-model Taurus PT92AF as his main weapon throughout the movie. His preferred method in combat seems to be rapid firing the Taurus, making good use of its 15 round magazine. A couple other henchmen are seen with PT92's throughout the movie.
Ruger GP100
A stainless Ruger GP100 is the most featured weapon in the movie. It is first seen as Officer Frank Washington's (Mark Frazer) sidearm, but eventually finds itself in nearly every characters' hands at some point. This is the case with several weapons in the film, as the low-budget production was limited to a select few functioning firearms. Therefore, several weapons get recycled as the movie goes on, but the Ruger GP100 is the most prevalent.
Smith & Wesson Model 15
The Smith & Wesson Model 15 is brandished by several police officers and gang members. When one of Yamashita's men threatens Frank and Joe with a Model 15, Joe exercises his Samurai training by cutting the man's arm off with a katana, and therefore disarming him. Crime boss Okamura (Gerald Okamura) briefly uses a Model 15 during an escape. Like the Ruger GP100, this was likely one single weapon that was recycled throughout the production.
Smith & Wesson Model 29
One of Yamashita's hitmen carries a Smith & Wesson Model 29 when carrying out a failed hit on Samurai Cop (which was filmed in the production warehouse of Hollywood Royal Pictures).
Single Action Army
One of Yamashita's men uses a Single Action Army revolver with ivory grips when threatening Frank. Later, in a continuity error, Peggy pulls the revolver out from her kitchen drawer despite showing a Taurus PT92SAF in the previous shot.
Star Model BM Non-Gun
Samurai Cop's Taurus PT92AF gets swapped out for a Star Model BM Non-Gun during the interior gunfights. The weapon flashes when fired, but the slide does not move and no shells are ejected. This was likely done for safety purposes, as blanks can still be dangerous at close-range.
Star Model B
One of Yamashita's henchmen carries a Star Model B during the final shootout.
Bruni Olympic 5
One of Yamashita's men is briefly seen carrying a blank-firing Bruni Olympic 5 Snub-Nose revolver. He gets shot by Frank before having a chance to use it.
Submachine Guns
IMI Uzi
When Joe Samurai and Frank beat up and apprehend a group of Yamashit's men, Yamashita (Robert Z'Dar) takes it upon himself to withdraw an IMI Uzi and murder his own men before they can be arrested. He apparently does this to follow the "code of silence". The Uzi later comes back briefly being used by Yamashita's unnamed mistress (Cameron Oppenheimer).
Shotguns
Mossberg 500
The Mossberg 500 is one of two shotguns seen in the movie, most notably used by Yamashita (Robert Z'Dar) in the movie's final shootout.
Winchester 1200 Field Gun
The Winchester 1200 Field Gun is the prominent shotgun used in the film. It is recycled several times, but is used the most by Yamashita's henchman "Johnny" when trying to hunt down Samurai Cop.
Grenades
M67 hand grenade
As if machine-gunning all his men down was not enough, Yamashita (Robert Z'Dar) casually withdraws a M67 Hand Grenade and proceeds to roll it under Frank's car - blowing it up.
