In the first half of the film, Sam (Robert De Niro) carries a Colt M1991A1 Series 80 pistol, a modernized version of the 1911. He hides the pistol in a gutter at the rear of the first rendezvous point. He uses the M1991 to take out a sniper and provide cover fire during the arms deal. He later switches to a SIG-Sauer P228 after the convoy ambush. While discussing weapons and other preparations early in the film, Sam tells Spence (Sean Bean) that he favors the "1911" after being asked what sidearm he prefers. When Spence remarks that it's an "old gun", Sam replies that "it served my country well for a long time" - undoubtedly a metaphor for Sam himself.
NOTE: IMFDB previously referred to Sam's pistol as an original M1911A1, but PropStore sold this gun many years ago on their web site, and it was actually an M1991A1 Series 80 being used as a 1911 stand-in. In several scenes of the movie, it is also possible to see the black plastic grips characterizing the M1991A1.
Besides his Colt M1991A1 Series 80, Sam (Robert De Niro) also carries a SIG-Sauer P228. He uses it in the stadium scene to kill one of the the two attackers and also during car chase after that. Near the end of the film, he attempts to kill Seamus (Jonathan Pryce) with it, but is shot. It can also be seen in promotional posters.
Vincent (Jean Reno) selects for himself a Beretta 92FS Inox fitted with Hogue combat grips. He is very skilled with the weapon and it is in fact the only weapon he uses throughout the entire movie. The Beretta used in this movie was eventually deactivated and sold by PropStore.
Gregor (Stellan Skarsgård) throughout the film is armed with a Glock 17L with the factory sights removed in order to allow attachment of a claw mount with a Bushnell HOLOSight (one of the earliest cinematic appearances of this device, aside from The Lost World: Jurassic Park). In the scene where he attempts to exchange the package, Gregor's Glock 17L is fitted with the HOLOSight, a suppressor(which indicates a custom uncompesated barrel), and a 20-round Glock 18 magazine.
When the arms deal goes south a bodyguard is seen with a Glock 19. The Dapper Gent (Jan Triska) also uses a Glock 19 when trying to rip off Gregor for the case.
Larry (Skipp Sudduth) selects a Taurus PT945 to carry before the arms deal. This gun is later used by one of the arms dealers at the site of the weapons/money exchange. Gregor (Stellan Skarsgard) also disarms "The Dapper Gent" (Jan Triska), a Russian mafia member, of this same pistol when he is dealing the package.
During the stadium scene, Sergi (Bernard Bloch) threatens Vincent (Jean Reno) with a Walther P5. When Sam (Robert De Niro) interferes, Vincent knocks Sergi's gun aside and his shot richochets into Sam's abdomen. He is then killed by Vincent with his Beretta 92FS Inox.
A German spy is armed with a Taurus PT92 during the stadium scene. It is recognizable as the PT92 by the lack of slide mounted safety and squared trigger guard.
Two of the convoy guards are armed with Skorpion SA Vz 61 submachine guns which they employ with great ineffectiveness, since they are distracted by a firecracker-based gunfire simulator.
During the first phase of the Convoy ambush, Sam (Robert De Niro) removes a SIG SG 551 assault rifle from the car and uses it to kill a few of the convoy guards. Also on the DVD cover of the film, Vincent (Jean Reno) can be seen holding one with its stock folded.
Sam takes out a convoy car with a type of LAW (Light Anti-Tank Weapon) he fires from his sunroof. The make and type is unknown, although it looks similar to an M72 LAW but it isn't. The body is too thick and it has an optical sight separate from the pop up sights of the LAW style launcher. Also the firing control button is completely unknown. It is probably a mockup fabrication, based on the LAW rocket design.
