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.).
Terence Wei's son Peter uses the stainless Beretta 92FS Inox during the opening drug bust at the beginning of the film. Two more Berettas with Inox finishes are visible in the case that John and Meg take from Loco (Clifton Gonzalez).
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.
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 on earlier versions of this page; it has the full-sized service model's angled trigger guard, full length slide and exposed hammer. A close-up of the slide 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). When he pulls the trigger, however, the hammer falls on the single chamber that's empty.
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.
A 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 SMG 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.
Some of Wei's men are armed with Heckler & Koch MP5SD6 submachine guns. It also appears that one of the SWAT officers in the opening scene of the film has an MP5SD, though it isn't seen clearly enough to be sure.
Rocky Mountain Arms Patriot Pistols are used by a few of Wei's men. Due to a continuity error, a thug whom John shoots in the final gun battle goes from using an Uzi to using a Patriot Pistol.

Strangely, the weapon was an Uzi a moment earlier, and it becomes an Uzi again after the thug is seen falling back and dying!
Heckler & Koch MP5K
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 due to the recoil pushing the suitcase back).
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).
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.
The SWAT team in the opening drug bust is armed with Colt XM177-type carbines, which are quite clearly not genuine XM177s (they have M16A2-style upper receivers, which means that they're actually some other AR carbine variant with the barrels chopped and fake XM177 flash hiders welded on).
During the final shootout, Collins wields another XM177 fitted with an M203 grenade launcher. He uses the M203 to blow up the step van driven by Meg. His gun has an SP1-style upper and lower receiver, unlike the SWATs' which have A2-style receivers.
When Meg Coburn finds Loco (Clifton Collins, Jr.) at a ghetto dice game, she grabs a stainless 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).
Ryker (Til Schweiger) uses a Heckler & Koch SR9(T) rifle fitted with a laser sight during the attempted hit in the movie theater. This gun is actually a conversion of an HK91, like nearly all of the SR9s seen in Hollywood movies.
In the final confrontation of the film, Terence Wei (Kenneth Tsang) uses a Walther P88 to shoot at John Lee. It was initially believed that this pistol was a SIG P226, but a close look at the slide release in the screenshot below indicates that the gun is almost certainly a P88.
One of the bodyguards seen at the club in the beginning of the film uses a SIG-Sauer P226, which he fires at John Lee just before Lee kills him with one of his Berettas.
A Heckler & Koch G3A4 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).
One of Wei's men wields a MAC-10 during the shootout at Meg's apartment, but he is taken down by John's USP before he ever gets to use it. Several of the gangbangers at the dice game also seem to have MAC-10s, including the one who asks Loco if he should "dump" on John and Meg.
