Alucard's second handgun is the Jackal, which was also made especially for him. The Jackal was made by Walter after Alucard's first encounter with Anderson - in fact, it likely was specifically designed with him in mind, considering the phrase ''Jesus Christ is in Heaven Now'', a variation on a similar statement on Anderson's equipment, is engraved on the side. The Jackal has an overall length of 39cm (the same length as the Casull), is made from pure silver, and weighs 16kg. The slide covers the entire top frame, and there are thus no creases or lines on the top part of the gun, making room for the engraving. Obviously, no human could possibly use this gun without being blown away by it. The breech also faces the left, instead of the right, so it's more of a sister gun to the .454, though its magazines can hold about the same amount of bullets that the Casull is capable of. The bullets are different as well, being a bigger 13mm, with a gold casing, a reinforced core for armor penetration, a mercury explosive and each bullet being baptized. Compared to the Casull, the Jackal is distinctly lacking in terms of aesthetic features, and is devoid of any contours on the side or frame save for the grip. This suggests that Walter designed the weapon immediately after Alucard's encounter with Anderson and did not have time to improve its appearance.
This gun is of fantastic proportions. No 13mm round was ever produced. A .50 alone would equal 12.7mm, meaning each bullet must be manufactured by Hellsing alone. It's curious as to how this weapon can weigh 16kg when a full size 7.62X51mm machine gun only weighs 11kg, the weight is probably necessary to control the 13mm rounds, though with a gun this heavy you could probably fire a .50cal BMG round and still have the same desired effect.
