The Mauser C96, also known as the "Broomhandle", is a semi-automatic pistol that is the preferred firearm of The Captain. Although originally designed as a sidearm, The Captain uses a modified version with an extremely long barrel. It first appears holstered in OVA III and it was first used in OVA IX.
The C96 was produced by German arms manufacturer Mauser from 1896 to 1937. A very popular pistol, approximately 1 million of them were manufactured by Mauser, as well as replicas manufactured by China and Spain. It's distinctive for its grip shaped like the handle of a broom, (hence its nickname) the box magazine placed in front of the trigger, and a detachable wooden shoulder stock which can double as a holster or carrying case.
With its shoulder stock, long barrel, and high-velocity cartridge, the Mauser C96 had superior range and better penetration than most other standard pistols of its day; the 7.63×25mm Mauser cartridge was the highest velocity commercially manufactured pistol cartridge in existence until the advent of the .357 Magnum cartridge in 1935.
It weighs 1.13 kg (39.9 oz) unloaded, but it is unknown how much the Captain's modified version weighs.
The original long-barreled version was 312 mm (12.3 in) long; the short-barreled "Bolo" version was 271 mm (10.7 in) long. The long-barreled version had a 140 mm (5.5 in) barrel, and the short-barreled "Bolo" version was 99 mm (3.9 in), +(20 in.) is estimated to be how long The Captain's extremely lengthened version is.
The pistol uses either a 7.63×25mm round, or a 9×19mm round. However, in China, the ACP .45 was used. It came in 6-, 10-, and 20-round integral or detachable magazines; 40-round detachable magazines were also made. It has a short recoil action and has a muzzle velocity of 425 m/s (1,394 ft/s), although it is unknown if The Captain's modified version keeps the same muzzle velocity. It is considered effective in a range from 150-200m.
