The fiction EM rifle(Electro Magnetic Pulse) which would actually be called EMP, is used several times through out the film. It is said to fire aluminum rounds at the speed of light, making it one of the only guns in movie history that actually could send someone flying when they are shot. The scope looks like a cam-corder with some type of green flashlight inside.
U.S. Marshall John Kruger (Arnold Schwarzenegger) steals a Desert Eagle off of another deputy during the plane shootout and keeps it until the zoo shootout when he runs out of bullets, convieniantly having 2 bullets left(as opposed to the 40 or so he fires before without reloading) to shoot out the crocidile glass exhibit, and shoot an approaching crocidile remarking, "Your luggage."
U.S. Marshal Robert Deguerin (James Caan) reveals his true colors by killing a woman with a dead assassin's Beretta 92SB, as noted by its briefly seen rounded trigger guard.
U.S. Marshall John Kruger (Arnold Schwarzenegger) uses a Glock 17 as his sidearm, apparently swapping out threaded and non-threaded barrels. He later steals one off of a man in the warehouse by the docks.
Seen in the hands of several thugs throughout the film and is also used by U.S. Marshal Robert Deguerin (James Caan) and Johnny Casteleone (Robert Pastorelli).
Kruger tells Lee Cullen (Vanessa Williams) that he works alone and if anyone ever says they are with him, to use his Smith & Wesson Model 36 "Bodyguard", a Smith & Wesson Model 36 with a rounded hammer shroud making it a "Bodyguard" model, to prevent clothing snag. It appears to use Harret grips, as they wrap aroud the shroud.
