The Hellsing Arms 454 Casull is one of two guns used personally by [[Alucard (Hellsing)|Alucard]]. It is a powerful semiautomatic pistol chambered in .454 Casull with a silver finish. It is far too powerful for a normal human to wield one-handed, but for a vampire like Alucard, it is an ideal weapon for dealing with regular vampires and other creatures of the night.
