Hellsing, like many anime, started as a manga series. Written by Kouta Hirano, the story revolves on an English organization called Hellsing, based on the original Van Hellsing. The organization's mission is obvious; to hunt down vampires and other supernatural threats to England.
Alucard's signature weapon is the Hellsing Arms .454 Casull (unofficially known as the 'Joshua'). This weapon is the first custom handgun made by Hellsing, and was specifically designed by Walter, the family retainer. It's essentially a very big semiautomatic pistol, with a length of 39cm. It's chambered for the mighty .454 Casull round, which finds use primarily in hunting large game, such as deer and bears. Of course, these bullets are special, being made out of silver obtained from melted holy relics, with an exploding property as well, making for a rather devastating cartridge against the legions of the night. The Casull is believed to be based upon the Colt 1911 (or its variants like the longslide), however it also bears a resemblance to early model Colt pistols. In some close up shots, one may note that the hammer is never fully cocked, indicative of either a double action or fast-action mechanism similar to the Daewoo DP51. The lengthy barrel and slide gives this gun incredible accuracy, and the weight at the front of the gun makes the massive round significantly more controllable. Something this extreme suits Alucard perfectly.
This is a low poly version of the anime gun. It is animatable.
