The Replacement Killers

Beretta 92FS

Chow Yun-Fat as John Lee and Mira Sorvino as Meg Coburn use the Beretta 92FS throughout the movie. Used most by John Lee in either single or akimbo style.

Browning Hi-Power

Meg Coburn (Mira Sorvino) uses a Browning Hi-Power handgun to take out a number of Wei's men during the shoot out at her office. She keeps it as her primary defensive weapon at her reception desk in a concealed holster while dealing with incoming clients.

H&K USP Full Sized

John Lee (Chow Yun-Fat) takes and uses an Heckler & Koch USP#Heckler & Koch USP H&K USP handgun from one of Wei's men and kills three or so other assassins during the shootout at Meg Coburn's office. It is not a compact model as erroniously referred. It has the full-sized service model's angled trigger guard, full length slide and exposed hammer.

Colt Model 635

One of Mr. Wei's men at the car wash is carrying a 9mm SMG version of the AR-15 rifle.

John Lee also utilizes a the same style of rifle. In the scene where he is to commit his assassination of the detective, he assembles the 635, along with scope and suppressor, but does not fire due to a crisis of conscience when he sees the detective with his family.

H&K MP5SD6

Some of Wei's men are armed with H&K MP5SD6 submachineguns.
