List of multiple barrel firearms

From Wikipedia, the free encyclopedia
Jump to: navigation, search

This page is a list of multiple barrel firearms of all forms from around the world.[1]

In a strict definition, a firearm must have at least the following characteristics to be considered a multiple barrel firearm:

  • At least 2 barrels, usually in the same calibre.
  • A firearm that has multiple barrels to hold rounds.
  • Capable of firing rounds simultaneously, or similar to that of a machine gun.
  • Bolts/Barrels may rely on other bolts/barrels to operate the weapon.
  • A firearm that has multiple barrels for rapid fire, barrel cooling purposes, hitting probability/increase accuracy.

Firearms that meet most of these criteria, but not all, are technically not multiple barrel firearms despite frequently being called such. For example:

  • The M16 assault rifle with underslung M203 grenade launcher and similar.
  • The OICW and similar.
  • The M45 Quadmount and similar.
  • Any device that holds more than at least 2 conventional firearms together to perform as a rapid fire weapons platform.

It must be noted that Combo weapons (IE M16 assault rifle with underslung M203 grenade launcher, OICW etc.) or Twin/Multiple Mounted weapons are NOT to be classed as Multiple Barrel Firearms. Weapons such as Derringer Pistols, Flintlocks, Survival Drillings, Double Barrel shotguns etc. that could be classed as an example but not necessarily worth listing here.

.45 ACP n/a
The Arsenal Firearms AF2011A1 is a 2 barrel variant of the M1911 pistol.
Flintlock Template:Country data unknown unknown caliber
is a pistol that features two or more barrels during the old days with or without a ramrod.
COP 357 Derringer  United States .357 Magnum
The COP 357 was a 4 shot Derringer type pistol chambered for the powerful .357 magnum round. It was designed by Robert Hillberg, based on earlier work on the Hillberg Insurgency Weapon. It was manufactured by the now defunct COP Inc. of Torrance, California (COP stood for Compact Off-Duty Police). The double action weapon is only slightly larger than the typical .25 automatic pistol, which made it a good choice for a defensive weapon or a police backup gun.
Garrucha  Brazil n/a
The Garrucha is a small pistol, similar to a Derringer, common in southern Brazil and Argentina in the early 20th Century. It is usually double-barreled, though with the barrels side-by-side rather than vertical as is common in American derringers, and the bores can be rifled or smooth. In Brazil, the most popular chamberings were for the .320 and .380 centrefire cartridges, similar to the .32 S&W and .38 S&W in appearance, but conical. They were also chambered for the .22 Short, .22 Long, .22 Long Rifle, and the .32, 8mm, and 9mm Flobert cartridges, among others.
Pepper-box 18th Century  United States n/a Civil-War America
The pepper-box revolver is a multiple-barrel repeating firearm that has three or more barrels grouped around a central axis. It mostly appears in the form of a multi-shot handheld firearm.
Howdah pistol 19th Century  United Kingdom n/a British Empire
The Howdah pistol was a large-calibre handgun, often with two or four barrels, used in India and Africa in the mid-to-late-nineteenth and early-twentieth centuries, during the period of British Colonial rule. It was typically intended for defence against tigers, lions, and other dangerous animals that might be encountered in remote areas. Multi-barreled designs were initially favoured for Howdah pistols because they offered faster reloading than was possible with contemporary revolvers, which had to be loaded and unloaded through a gate in the side of the frame.
Lancaster Pistol 1884  United Kingdom .455 Webley British Empire
The Lancaster Pistol was a multi-barrelled (either 2 or 4 barrels) handgun produced in England in the mid-late 19th century, chambered in a variety of centrefire pistol calibres—chiefly .380", .450 Adams, .455 Webley, and .577 calibre. It was a modernised version of the pepper-box pistol popular in the early-mid 19th century. Unlike these earlier guns, which had percussion cap ignition the Lancaster was chambered for the more modern brass cartridges. It had a faster rate of fire than the standard-issue Adams revolver and was. often fitted with a Tranter-type trigger to overcome the heavy pull of the revolving striker.
Mossberg Brownie 1920–1932  United States .22LR n/a
The Mossberg Brownie was a four-barreled, .22 Long Rifle pistol, similar to a derringer or pepperbox, produced by O.F. Mossberg & Sons from 1920 to 1932. The Brownie was based on an earlier pistol patented and licensed to the Shattuck Company by Oscar Mossberg.

Standard Manufacturing Company DP-12 2014  United States 12ga n/a
The Standard Manufacturing Company DP-12 is a double barrel pump action shotgun.
Winchester Liberator  United States 12ga n/a
The Winchester Liberator is a 16-gauge, four-barrelled shotgun, similar to a scaled up four-shot double action derringer. It was an implementation of the Hillberg Insurgency Weapon design. Robert Hillberg, the designer, envisioned a weapon that was cheap to manufacture, easy to use, and provided a significant chance of being effective in the hands of someone who had never handled a firearm before. Pistols and submachine guns were eliminated from consideration due to the training required to use them effectively. The shotgun was chosen because it provided a very high volume of fire with a high hit probability. Both Winchester and Colt built prototypes, although the Colt eight-shot design came late in the war and was adapted for the civilian law enforcement market. No known samples were ever produced for military use.
Paradox gun Template:Country data n/a 8ga or 10ga
A Paradox gun is a firearm made by Holland & Holland with the last two to three inches (5.1 to 7.6 cm) of the muzzle rifled and the rest smooth, intended to be used as both a rifle and shotgun. Paradox guns served the needs of hunters in India and Africa who might encounter both small and large game but needed to carry only a single gun. A Paradox gun allowed the use of a shot with a specific choke for small game and Paradox bullets for large game: with the bullet engaging the rifling grooves as it swaged through the choke. This gave an advantage over a slug barrel, which could only employ cylinder bore barrels (no choke). Modern users of Paradox guns have the same advantage, especially in areas where the bird and deer hunting seasons overlap. Paradox cartridges have been loaded with either hollow-point or solid bullets of varied composition. The current Holland & Holland cartridge is loaded with the most useful of these, the 740-grain (48 g) lead solid.

H&K P11  Germany 7.62mm x 36 Germany
The HK P11 is a Heckler & Koch pistol designed as an underwater firearm. Since ordinary-shaped rounds are inaccurate and have a very short range when used underwater, this pistol fires steel darts about 10 cm long. It has five barrels, each of which is loaded with a cartridge, giving the gun a pepper-box appearance, and it is electrically ignited from a battery pack in the pistol grip. After firing all five cartridges, the barrel unit must be sent back to its manufacturer for reloading. In the past, Heckler & Koch has denied knowledge of its existence.[2]
Mk 1 Underwater Defense Gun  United States n/a US

Double rifle Various Various
A double-barreled rifle or double rifle is a type of sporting rifle with two barrels instead of one, available in either side-by-side or the more accurate over-and-under barrel configurations. Double rifles are one of the family of combination guns. In general, double rifles are much more expensive than the much more common magazine-repeater rifles, and, owing to the large-calibre cartridges commonly used, have to withstand very high levels of recoil. Because of their ability to fire two quick shots, double rifles are often used for the hunting of dangerous game in Africa. While today double rifles are typically associated with African big game hunting, double rifles saw their most extensive use during the colonial period in India.

The Montigny mitrailleuse was an early type of crank-operated machine-gun developed by the Belgian gun works of Joseph Montigny between 1859 and 1870. It was an improved version of the "Mitrailleuse", (English: Grapeshot shooter) invented by Belgian Captain Fafschamps in 1851 which was a fixed 50-barrelled volley gun. It was designed to defend narrow defensive positions such as the moats of fortresses. The Belgian army initially purchased Fafschamps volley guns. Only later did they acquire Montigny mitrailleuses. Joseph Montigny also promoted and sold the weapon for offensive field use by placing the weapon on an artillery carriage.
