Brill (Gene Hackman) carries an original U.S. Army Colt M1911 .45 ACP, which he holds on Robert Dean (Will Smith) at a hotel in order to ensure Dean is not a federal agent pursuing him. Apparently he doesn't regard him as a real threat, since the gun isn't cocked and can't be fired.
Robert Dean (Will Smith) takes a 2nd Generation Glock 17 from a police officer, which he fires several times while being pursued by Reynolds' men in a tunnel. He later gives it to his wife for her own defense, and it is not seen again afterwards.
Brill keeps a sawed-off Remington 870 shotgun in his El Camino, which he gives to Dean to use against the NSA agents while they are being pursued. Brill later uses the shotgun to intimidate the driver of a Mercedes that he and Dean carjack.
Nearly all of the NSA operatives under Reynolds' (Jon Voight's) command who are pursuing Robert Dean carry 9mm SIG-Sauer P226 pistols. Reynolds himself wields a P226 at the climax of the film, which he uses to shoot Brill in the hand.
Jones (Scott Caan) is the only one of Reynolds' men who carries a Beretta 92FS instead of the SIG P226s that are favored by the rest of the NSA operatives.
Krug (Jake Busey) is seen wielding a Heckler & Koch MP5K at the end of the film, but before he can use it, he is killed by one of the mobsters when he attempts to break up the confrontation between Reynolds' agents and Pintero's thugs.
Savage/Stevens Model 311 sawed-off double-barrel shotgun
A chef in Pintero's restaurant kills Krug with a Savage/Stevens Model 311 sawed-off double-barrel shotgun. He later uses it to threaten Dean before being captured by FBI agents.
One of Pintero's men uses a Smith & Wesson 5904 pistol in the final shootout, which is the same as the Smith & Wesson 5906 but with a blued finish over the 5906's stainless finish.
