The Beretta 92FS features prominently throughout the film as the weapon of choice for John Lee (Chow Yun-Fat). As in most of Chow Yun-Fat's films, the character of John Lee frequently wields Berettas "akimbo"-style as he executes Triad henchmen. Meg Coburn (Mira Sorvino) also wields the 92F in various scenes, most notably at the end, after she and John acquire a large suitcase full of Berettas and ammunition from the gun dealer Loco (Clifton Collins, Jr.).
Meg Coburn (Mira Sorvino) uses a Browning Hi-Power to take out a number of Terence Wei's men during the shootout at her office. She keeps it as her primary defensive weapon at her reception desk in a concealed holster while dealing with incoming clients. It's hard to tell precisely which model it is, but it appears to be a Mark III model of recent manufacture.
John Lee (Chow Yun-Fat) takes and uses a full-size Heckler & Koch USP from one of Wei's men and kills three or so other assassins during the shootout at Meg Coburn's office. He subsequently uses it through much of the film, and later trades it to Meg Coburn during the shootout at the car wash. It is not a Compact model as erroneously referred; it has the full-sized service model's angled trigger guard, full length slide and exposed hammer. A close-up of the extractor when he fires the gun into the stomach of its original owner reveals that it is the 9x19mm model.
John Lee briefly takes a snub-nosed Ruger SP101 with a spurred hammer from one of Wei's men of unknown caliber (most likely .38 Special). It misfires when he tries to use it.
A number of Colt 9mm submachine guns are used throughout the film by Terence Wei's men. During the shootout at the car wash, John Lee also gets ahold of one and uses it to kill one of the thugs.
The civilian carbine version of the Colt SMG is also the weapon that John Lee uses when he fails to kill Stan "Zeedo" Zedkov's (Michael Rooker's) son in the film's pivotal assassination scene. The 9mm Colt carbine in this scene is fitted with a suppressor and scope. Although it seems to be an unusual choice for a sniping mission, the range of the shot, combined with the suppressor on the gun, would be adequate for John's purposes; it is likely he chose a 9mm carbine because this caliber can be suppressed easily.
A number of Heckler & Koch MP5Ks appear throughout the film in the hands of Terence Wei's men, the most common being the MP5K-PDW variant with the side-folding stock and threaded three-lug barrel. During the shootout at the car wash, John Lee takes one of these weapons from the blond thug and fires it at the other assassins.
During the shootout at the arcade, Ryker (Til Schweiger), one of the titular "Replacement Killers", uses an MP5K in the special H&K briefcase designed to hold this gun. He fires it incorrectly, holding it with one hand at his side, rather than using both hands to hold it horizontally (in real life, firing it the way he does is dangerous and can cause the shooter to put bullets in their calf).
Ryker (Til Schweiger) also uses a Heckler & Koch MP5A3 instead of the MP5K he was seen using earlier in the briefcase. This is the subgun that he uses to kill the police officers in the parking garage. This is usually assumed to be a continuity error; however, if you watch, you can clearly see that he reaches under his trench coat and pulls the MP5A3 out (where it has been hanging by a sling). Why he ditches the MP5K for a slightly larger version of the same weapon is a mystery.
Collins (Danny Trejo), the other of the two "Replacement Killers", fires at John and Meg with a Beretta PM12S during the shootout in the arcade. He subsequently uses this weapon to shoot at the police in the parking garage.
During the final shootout, Collins wields a Colt CAR-15 Commando variant (I don't know what model, but it clearly has the bulky older-style flash hider) fitted with an M203 grenade launcher. He uses the M203 to blow up the step van driven by Meg.
Michael Kogan (Jürgen Prochnow), Terence Wei's right-hand man, uses an IMI Desert Eagle .357 Magnum as his sidearm throughout the movie. It appears to be the earliest Mark I model.

Kahr K9
When Meg Coburn finds Loco (Clifton Collins, Jr.) at a ghetto dice game, she grabs a Kahr K9 from his waistband and holds it on him (Loco himself later refers to the gun erroneously as a "Fo-Five"). She subsequently uses the gun in the shootout at the movie theater.
Collins (Danny Trejo) uses an FN FAL 50.61 (the "Paratrooper" model with the folding stock) fitted with a laser sight during the attempted hit on Zeedo's son at the movie theater. Zeedo himself also uses a Patatrooper FAL, albeit without a laser sight, in the climax (it's probably just Trejo's gun being reused in a different scene).

At the end of the film, Terence Wei (Kenneth Tsang) uses a SIG-Sauer P226 to shoot at John Lee. One of the bodyguards seen at the club in the beginning of the film also uses one.
On second thought, I believe Wei's gun may actually be a Walther P88.
A Heckler & Koch G3A3 is wielded briefly by Michael Kogan (Jürgen Prochnow) during the shootout at the car wash (it's fired on full-auto, so it's not an HK91 as previously stated).
Two of the thugs at Meg's office uses sawed-off Remington 870 shotguns with shell holders mounted along the receiver.
