The revolver is a 44 Magnum cartridge. It was made famous as the weapon of choice of "Dirty" Harry Callahan (Clint Eastwood) in the Dirty Harry films. This gun is probably more practical than the Smith & Wesson Model 500 due to the fact that it's recoil is easier to control and has a higher capacity upgrade. Due to the fact that these weapons are so powerful, the ammunition is very hard to come by. Thus ammo conservation is essential. Its ability to pierce multiple opponents at once and having the second highest damage rating (Only behind the S&W M500) of all the handguns makes it invaluable to have in a pinch.
