Hellsing ARMS Casull

The Hellsing ARMS .454 Casull Auto, sometimes shortened to Casull, is a semi-automatic handgun that is one of Alucard's favorite weapons of choice. The engraving on the frame of the gun (Hellsing ARMS 000001) indicates that it is the first custom weapon ever made by Walter C. Dornez.


The Casull is a classic semi-automatic handgun, based on pre-WWI handgun designs by Colt, most notably Colt's popular handguns, the M1911 and the M1903. It weighs approximately 6 kg unloaded and has a magazine capacity of six (plus one in the chamber) .454 Casull cartridges. It has a single-stack magazine as seen in other .45-caliber handguns like the M1911 and SIG P220.

The overall design of the Casull is simple, using the Browning short recoil mechanism. Its most recognizable feature is its long slide, counteracting the weapon's heavy recoil with its weight. The barrel is 10 inches long (specified on the slide) and finished with titanium nitride which gives it a characteristic gold color.

The Casull is too heavy and unwieldy for a human to use, yet a perfect match for Alucard's strength.

Ammunition and UsageEdit


The Casull in use by Alucard in the first episode

The gun fires custom-made explosive .454 Casull rounds, with the steel bullets bearing a core made from the melted silver Christian cross from Manchester Cathedral. However, when Alucard first introduces the gun in Volume 1 while dealing with the vampire in Cheddar, he says that it fires 13mm rounds. A possible explanation would be that the gun was originally chambered in .454 Casull, but now fires a custom round necked up to 13mm, as the casings shown ejected by the pistol are bottle-necked and rimless, while the real Casull round uses a straight walled rimmed case.

Early on, Alucard used the Casull to terminate all sorts of vampires, including the priest vampire from Cheddar. Alucard's battle with Luke Valentine in Volume 2 shows him firing 7 rounds at Luke before the slide clicked back on empty. However, in both the anime and the manga, the Casull fails to kill Alexander Anderson, so Alucard specifically asks Walter for "something bigger" (however, he may have been refering to the ammunition).


Alucard Prepares The Casull

Even though Alucard has stated that the round uses explosive silver bullets, the traits exhibited by the bullet wounds show that it displays characteristics similar to that of a full metal jacketed pistol round, when it punches through the lung of two people without having the round explode.

Although Alucard has reloaded it at many points throughout both the manga and anime, Hirano has joked in the back of volume 1 that "They're all cosmoguns that can hold a million rounds". This is also evidenced in the first OVA, where Alucard takes out a large group of ghouls without reloading.

Trivia Edit

  • When used together with the Jackal, the Casull gives Alucard an appearance similar to Dante, the protagonist of the Devil May Cry series. Both are red-clad transhumans (a vampire and a half-demon, respectively) who wield a white and a black gun simultaneously (Casull and Jackal for Alucard, Ebony and Ivory for Dante).
  • However the two pairs of guns vary vastly in stopping power as Dante's pistols are chambered in much weaker .45 ACP and instead are powered by Demon energy to shoot rapid barrages w/ infinite ammo.
  • Along with other references, such as Seras's Harkonnen, the use of Casull and Jackal may be a reference to the antagonists of Frank Herbert's novel Dune--specifically, the Harkonnen custom of wielding a poisoned long knife with a black glove in the right hand and a short knife with a white glove in the left.
  • The rounds fired by the Hellsing Arms .454 Casull Auto is a rimless cartridge. Since the .454 Casull (not to be confused with the .454 Casull Auto from the manga and anime) is a rimmed cartridge designed to be used in revolvers in real life it can be confirmed that the round that the Hellsing Casull fires only exists in the manga and anime since no rimless .454 Casull exists. Therefore it can be assumed that the .454 Casull Auto uses the same bullet from the .454 Casull cartridge and the casing is a proprietary design made by Hellsing Arms.
  • Despite the slide reading .454 (roughly 11.23mm) Alucard specifically names the rounds as 13mm. This could be due to a higher caliber barrel being fitted for the gun, or a misinterpretation, as the rim diameter of the .454 Casull is 13mm.
  • Alucard has been seen with the ARMS Casuall in WWII flashbacks which is anachronistic for the .454 Casuall round as it was not developed until 1957.
  • It made its final appearance in OVA 9, it's nowhere to be seen after it was last shot to Luke Valentine.
  • If one would add the numbers found in the .454 Casull, the sum will be 13, hence the 13mm rounds.
