Hellsing Combat Pistol 'Jackal'

The Hellsing ARMS 13 mm Auto Anti-Freak Combat Pistol, Jackal (usually referred to as simply "The Jackal") is a specialized firearm and one of Alucard's personal weapons.

Profile
The Jackal is a massive pistol made especially for Alucard. With a length of 39cm (16 in), weight of 16kg (35lbs), and a black gunmetal construction, it is one of the most powerful hand weapons featured in the series. The words Jesus Christ is in Heaven Now are engraved upon it, in mockery of a similar statement on Alexander Anderson's gloves.

Its unique design makes it seem as if it doesn't have a pistol slide; however, the entire upper assembly is the slide, and moves only a minimal distance compared other guns', making it appear as if there is no pistol slide. The Jackal has its silver ejector port on the left side, implying that it is meant to be used in conjunction with the Casull (sending the shells to the left prevents them from obscuring the wielder's view). In the manga and anime Alucard is usually shown wielding both guns. Later it had a explosive device hidden inside of it by the Doctor, who used it as a failsafe in case Alucard was to gain a significant edge against Millennium with it.

Usage
So far, the only person ever seen using the gun has been Alucard; he ordered it from Walter after his draw with Anderson, since the Casull failed to kill the Iscariot paladin. In fact, the inscription on its side implies that it was meant especially to end Anderson's life. Because of the Casull's failure, Alucard had expressed the desire for "something bigger," from Walter (probably referring to the ammunition: the gun's size rarely affects its bullets' power), and the butler delivered in full.

At the time the Jackal was ordered, Walter was a secret agent for Millennium, and it was in fact the Doctor who constructed the Jackal. Alucard used it in every fight after his first encounter with Anderson, except with Rip van Winkle, whom he bested with bare hands. The end of the Jackal's formidable battle power came when Alucard returned to England. In the London battle, the Doctor activated the explosive failsafe, permanently destroying it. It is not known whether its reconstruction was attempted after the siege of London.

Bullets and Rounds
The Jackal fires a huge 13 mm, mercury-core bullet, with casings of blessed Macedonian silver. The powder charge is a special formula known as "Marvell's Chemical Cartridge N.N.A.9." The rounds are also explosive hollow-tips, and it has six rounds per magazine. The bullets were designed almost exclusively to be used against Iscariot's Alexander Anderson, who shrugged off the Casull rounds with ease; however, it also makes for an extremely effective anti-vampire combat weapon. Like the Casull, Alucard has reloaded the Jackal various times but has also greatly exceeded the number of rounds per magazine. The reason he is able to do this is never explained but Kouta Hirano has joked in the back of volume 1 that "They're all cosmoguns that can hold a million rounds".
