Lara Croft Tomb Raider is the 2001 film adaptation of the popular videogame. Angelina Jolie stars as the iconic adventure hero who searches around the world for a mysterious relic. Jolie would reprise her role in the sequel Lara Croft Tomb Raider: The Cradle of Life.
The following weapons were used in the film Lara Croft Tomb Raider:
The signature pistols of Lara Croft (Angelina Jolie) in the film are Heckler & Koch USP Match with stainless slides. The handguns are 9mm models, not .45 ACP as previously believed. As in the original videogame, she keeps her handguns prominently holstered on her thighs and almost always draws them both at the same time. She's also carries custom mag holders to facilitate quicker reloading of both handguns.
Walther P99
Manfred Powell (Iain Glen) carries a Walther P99 through much of the film, most notably during the shootout with the statues at the temple of light and during his fight with Lara at the end of the movie. Alex West (Daniel Craig) is seen using one as well (kind of ironic, huh?).
Smith & Wesson 6904 Pistol
Smith & Wesson Model 10
Manfred Powell is seen pulling a Smith & Wesson Model 10 revolver on Lord Richard Croft (Jon Voight) in a vision Lara has after obtaining the triangle.
Beretta 92FS
The Beretta 92FS by many villians and Lara in a deleted scene in which Lara breaks up Alex West's (Daniel Craig) poker game. Alex also picked one up when he came out of the shower after hearing Lara sneak into his room.
Submachine Guns
Steyr TMP
Lara Croft (Angelina Jolie) acquires a Steyr TMP from a member of the raid team and uses it to score several kills.
Heckler & Koch MP5A2
A photo of Lara's team she apparently previously served with with armed with Heckler & Koch MP5A2s. Some can also be seen on the gun rack in the equipment of Lara's home.
Heckler & Koch MP5A3
A guard at the airfield was carrying a Heckler & Koch MP5A3 briefly. A couple also help MP5A3s in the Artic.
Rifles
AKS-74U
Alex West's (Daniel Craig) held one when they were in the jungles.
Heckler & Koch G36K
A Heckler & Koch G36K is employed by the Iluminati operatives during the raid to the Croft Manor with suppressors and in the expedition to the artic, some of them were fitted with laser sights.
Shotguns
Nickel plated Remington 870 Shotgun
Hillary, Lara's butler, used a nickel plated Remington 870 shotgun during the raid on the manor. It is NOT the Stainless Steel 870 Marine Magnum, but the classic 870 riot configuration with a nickel finish.
Machine Guns
Browning M2HB
A visually modified Browning M2HB machine gun is seen mounted on the Russian transports that take Lara and the others through Siberia.
Other
Gun Rack
Lara's display of guns contain a couple MP5s, a Skorpin, a G36K and a Micro Uzi
Improvised Gun - SnapOn™ Impact Hammer (pistol)
In the film Lara Croft uses a SnapOn™ Impact Hammer or Air Hammer as a weapon to knock out an attacker. Though the device is very 'pistol-like' in shape, the manufacturers go to great lengths 'not' to call it a 'gun'.
Behind the scenes training
Angelina Jolie was reportedly trained by a former SAS member, name not known at the moment. At least it looks like she took the training seriously, but I don't know about the training on dual wielding handguns.
