Parrish's PT92 changes to a Beretta 92FS Inox during the final shootout. Norwood later takes the gun for herself to use. A Russian mobster is seen briefly with one in the wedding shootout.
Diane Norwood (Tia Carrere) uses a DA38 9mm O/U (over and under) Derringer during the opening wedding sequence when she arrests her fiance's father, the leader of the Russian mafia.
Max Parrish's (Thomas Ian Griffith) main sidearm is a Glock 17 2nd generation 9mm for about 3/4ths of the film. Other people as well can be seen using the same gun as well.
Diane Norwood's (Tia Carrere) sidearm of choice is a 9mm SIG-Sauer P228. She uses it for several moments throughout the film. Due to the low budget of the movie, at least a few other mobsters can be seen using the same P228.
When Livingston's men catch Parrish and Norwood, the Train Yard Hood has a Taurus PT92, as noted by its frame mounted slide stop safety. It then switches to a Beretta Centurion, noted by its slightly shortened barrel and slide mounted decocking safety.
Parrish keeps a stainless Taurus PT100 with wood grips and no third position safety-decocker as one of his spare pistols. It is noted by its frame mounted slide stop safety. It is identified as a PT100 based on Lawton claiming it is a .40 caliber. It is later replaced by the 92FS in the film, which appears to be a continuity error.
Parrish keeps a Walther PPK as one of his backup guns. He shows some trouble finding the gun towards the end of the film, finally finding it after the action is over.
Parrish uses a Winchester 1300 when Lawton is busted out of jail. He uses it to shoot a LAW rocket out of the air, which would be impossible in real life.
Used by mobsters and Norwood in the end of the film. Norwood uses it in the standoff between the 4 main characters. Seen briefly used by Russians during wedding shootout.
A Chinese mobster is seen briefly using the selective fire variant of the Mini-14, the AC556 rifle, seen using a thermal protective magazine. One can also be seen used by a Russian during the opening wedding shootout.
Most of Thomas Livingston's men are armed with these 5.56mm Norinco AKs, noted by their .223 syle magazine and hooded front sight. Several Russian mafia members use them as well. It is most likely the same gun used multiple times throughout the film. It is not a standard Type 84 Configuration, most notably outfitted with an underfolding spike bayonet (aka "pig-sticker" bayonet).

Probably from being used so much for the film.
Other
Arwen 37 MK1
Parrish fires an Arwen 37 MK1 37mm less-lethal revolving launcher from a car window during the final action scene. The gun does absolutely nothing when fired so it is probably a smoke or tear gas launcher.
All mobsters at the wedding have to put down their guns on the front table. Since it is a low budget film, probably half of these guns are seen used by other people throughout the whole film. Seen are all the revolvers soon to be listed on the page, three 1911 type pistols are seen and a Glock 17 next to one. A Norinco type 84S is seen later to be used by almost all the bad guys later on, and an MP5K later to be used at the wedding shootout. A Ruger P89 pistol is visible in the next shot, along with the Beretta Centurian, the Taurus PT92, and the Beretta 92FS INOX, all to be seen later in the film. Also, a Smith & Wesson handgun is visible and a nickel plated SIG-Sauer P225.
