.44 Magnum (FarCry 3)

“An American-made revolver that packs some serious punch at close range but has limited ammo capacity. It can be used while on the Zipline.”
— in-game handbook

“The magnum revolvers here on Rook Island are actually part of a shipment originally bound for disgruntled North Korean dictator Kim Jong-il. Vaas, always on the lookout for more firepower, intercepted the cargo ship, seized the handguns and left a present in their place. No one knows what it was, but Kim Jong dropped dead the day it arrived. Coincidence? Do corporate lawyers have souls?”
