When Chelios tries to interegate Orlando, several of the gangsters in the club draw Desert Eagles. One of these Desert Eagles is an Early Mark I in .44 Magnum, the other is a flashpaper gun. Chelios later aquires one of these Desert Eagles off of Verona's brother in the back alley-way. Since he has to fire it at such close range, the gun is a flashpaper model during that scene. Later when Chelios goes to the hospital in search of epinephran, the Desert Eagle changes to the Mark I model, which he fires several shots from before leaving it in the hospital elevator.
Kahr K9
Chelios gets his hands on a Kahr K9 pistol which he uses to hold up one of the men on the textile mill roof before throwing him off. He then uses it for the start of the shootout in the mill before it runs out of ammo.
SIG-Sauer P226
One of the thugs in the textile mill is armed with a SIG-Sauer P226 and has it taken by Chelios after he jams his hand into a sewing machine. He uses it for the second half of the shootout before trading it with a Glock 17.
Glock 17
When interigating Orlando in the club, one of the gangsters draws a Glock 17 2nd Generation and holds it on him. Later in the film, one of the shooters in the textile mill uses a Glock 17 to shoot at Chelios before Chelios kills him and takes the gun for his own use.
Later in the film during the roof shootout, one of Don Kim's thugs uses a Glock 17 fitted with a sound suppressor. The muzzle is not seen, so whether or not it is a Glock Pro is not known.
FN Five-seveN Tactical
Chelios is seen using an FN Five-seveN Tactical, the modified version of the Five-seveN with a laser mount and safety switch (the original model is double action only) as he prepares to kill Don Kim (Keone Young). His is fitted with a laser and a thread on suppressor.
Beretta 92FS
A Beretta 92FS is seen in the hands of one of the gangster in the club and is the standard issue sidearms of the police department. Chelios steals a Beretta off and officer at one point and taunts his with it before tossing it away to give him enought time to steal his bike.
At one point in the film, an assassin tries to kill Chelios and his girlfriend Eve (Amy Smart) with a sound suppressed Beretta 92FS but Chelios kills him before she is even aware.
