James Bond (Pierce Brosnan) carries a Walther P99 throughout the film, fitted with a suppressor in one scene. In the first half of the pre-credits sequence, Bond is carrying a P99 that is revealed to be a remote grenade, triggered by a button hidden in his eyeglasses.
M1911A1
The Swiss bankers that Bond meets during the precredits sequence in Spain all carry M1911A1s. Bond uses one to try to get information from one of the bankers. Valentin Zukovsky (Robbie Coltrane) fires a M1911A1 during the gunfight in his caviar factory. Many of Renard's men use M1911A1s and Elektra King's Series 70 (taken and used by Bond) turns into a standard 1911 when Bond jumps into the water. This M1911A1 is also a typical "Hollywood" gun, firing about 20-30 rounds despite its 7-8 round capacity.
Beretta 92FS
The Spanish police officers who burst into the banker's office are armed with Beretta 92FS pistols.
Heckler & Koch G36K
The Cigar Girl (Maria Grazia Cucinotta) attempts to snipe Bond with a Heckler & Koch G36K fitted with a laser pointer, but doesn't score a hit. Bond tells M he knows the sniper was "professional", even though most professional snipers wouldn't use the laser like the Cigar Girl does. This is one of the first movie appearences of the G36 rifle.
Heckler & Koch HK-21
A heavily modified Heckler & Koch HK21 machine gun is mounted on the speedboat driven by the Cigar Girl. She fires it at Bond but the gun is eventually knocked off of its tripod when Bond's boat jumps through it. It has the ergonomic grip and stock from a PSG-1 with other modifications, such as a front handguard/barrel jacket.
Armsel Striker
As a last ditch attempt to get rid of Bond, the Cigar Girl (Maria Grazia Cucinotta) fires an Armsel Striker, modified to fire grenades, at him, but eventually throws it on the deck of her boat. Actually its a factory issue Cobray Street Sweeper 12-Gauge with the folding stock removed. It was also incorrectly catalogued in the 2006 Guns of James Bond auction at Christies.
Smith & Wesson 669
The Cigar Girl (Maria Grazia Cucinotta) uses a Smith & Wesson 669 after ditching her boat, and uses it to threaten a group of people near the hot air balloon, eventually using it to destroy her balloon and commit suicide.
AKS-74U
Elektra King's security team in Azerbaijan carry the AKS-74U. The Russians at the Kazakhstan ICBM base also have AKS-74Us.
Pretty sure these are AKMSs, not AKS-74Us. The barrels are too long and of course they are underfolders. - Gunmaster45
Guard on the left holds AKMS, but guard on the right holds AKS-74U. - RedCharger
The guard on the right holds an AKS-74, not an AKS-74U. The barrel is way too long to be an 'U'. Ramell 00:33, 15 July 2010 (UTC)
M16A1
The military around Elektra's pipeline in Azerbaijan have M16A1 assault rifles.
Steyr TMP
The Parahawk assassins that attack Bond and Elektra in the Caucus Mountains have Steyr TMP submachine guns. Several other terrorists, including Mr. Bullion (Goldie) use TMPs and Bond himself has one for a shot at the caviar factory (although surrounding shots have Bond with his P99, leading to the conclusion that this is a continuity error).
Smith & Wesson Model 66
When Bond enters Zukovksy's casino with his X-ray glasses on, he sees several heavily-armed people. One man, a bodyguard, has two large Smith & Wesson revolvers under his coat. Another man, who threatens Bond before Bond gets the best of him, carries a Smith & Wesson Model 66 under his left armpit, which Bond gives the bartender in exchange for a "shaken, not stirred" vodka martini.
Kel-Tec P11
A woman in Zukovsky's casino has a Kel-Tec P11 concealed on her person, which Bond sees with his X-ray glasses.
Makarov PM
Several of the Russian soldiers at the Kazakhstan ICBM base have Makarov PM pistols, one of which is comandeered by Bond and fired akimbo with his P99 in one shot.
FN P90
Renard (Robert Carlyle) and many of his men use the FN P90 throughout the film, notably at the nuclear test site, Zukovksy's factory, and the final shootout. Bond uses one briefly during the test site shootout.
Heckler & Koch MP5K
When fleeing the test site, Renard uses a Heckler & Koch MP5K. One is used by Zukovsky when he and his men attack Maiden's Tower near the climax. He notably uses it to kill his treacherous henchman, Bullion.
Ruger KP89
Elektra's bodyguard Gabor (John Seru) carries a Ruger KP89 as his personal sidearm.
If you look closely, you can see Gabor has an M1911(A1) in his waistband.
Cane Gun
Zukovksy aims a single shot gun concealed within his cane at one of the straps in the chair Elektra is using the torture Bond, misleading her to believe that Zukovksy was trying to kill Bond with his last breaths but was really trying to free him from her.
Colt Mk IV Series 70
Elektra King (Sophie Marceau) is armed with a Colt Mk IV Series 70, which Bond takes from her and shoots her with. He tucks the pistol into his waistband and jumps into the water but when he emerges on the submarine, he has a standard 1911.
SIG-Sauer P228
Renard draws a SIG-Sauer P228 on the submarine, dropping it when he heads for the reactor.
Glock 17
Some of Renard's men on the submarine carry Glock 17 pistols, firing at Bond during the brief shootout.
