Magnum

Magnums are high caliber pistols, that appear in the Tomb Raider Series. They are a staple of Lara croft's arsenal.

Tomb Raider 1996
Magnums are like the standard pistols, but better. Much better. You can notice the power just hearing the sound it makes when shooting. They are a great pair of guns that loses only in firepower to the shotgun, but it is faster and you don't have to worry about ammo because it is abundant and you should have a lot of it by the time you reach the Lost Island levels.

They do twice the damage then the standard pistols.

Tomb Raider III
A single Desert Eagle is available in Tomb Raider III and Tomb Raider Chronicles. It is capable of killing a human enemy in two shots and armored enemies in three. It has a very slow rate of fire and high recoil. A very powerful gun that is very useful.

Tomb Raider: The Last Revelation
The Revolver is a very effective weapon, first available in Tomb Raider IV The Last Revelation, making its return in Tomb Raider Chronicles. It is one of the few weapons that can be combined with the Lasersight for manual aiming. The revolver in the games is a generic big-bore revolver with nearly as much firepower and accuracy as the Desert Eagle. Since Lara does not reload in real time, the 6-shot limit is not a problem. Does 21 damage per shot, takes just under twice as long to fire as the Pistols, or half the time it takes to fire the shotgun. The revolver seems to be a Smith and Wesson or Taurus model of revolver in this game.

Tomb Raider: Anniversary
The Magnums return as "Dual 50. Cal Pistols". They function the same as the Magnums from the original game. They are taken from Pierre DuPont before he is killed by the Centaurs, though they can be acquired in a small cove in the Coliseum. After reaching Natla's Mines they can be acquired in the lava room after using the drill to break through the barricade. Unlike the original Magnums which had odd appearances, the Dual 50. Cal Pistols has the appearence of grey-black Desert eagle.

Lara Croft and the Guardian of Light
Two different models of Magnums appear:

Magnums
Deal double Damage of the standard pistols and have a better rate of fire. They are based on Smith and Wesson Model 629.

Hand Cannons

Lara Croft and the Temple of Osiris
