A double-barreled shotgun, also known as a double shotgun, is a break-action shotgun with two parallel barrels, allowing two single shots that can be fired simultaneously or sequentially in quick succession.
A shotgun is a long-barreled firearm designed to shoot a straight-walled cartridge known as a shotshell, which discharges numerous small spherical projectiles called shot, or a single solid projectile called a slug. Shotguns are most commonly used as smoothbore firearms, meaning that their gun barrels have no rifling on the inner wall, but rifled barrels for shooting sabot slugs are also available.
In firearm designs, the term single-shot refers to guns that can hold only a single round of ammunition inside and thus must be reloaded manually after every shot. Compared to multi-shot repeating firearms ("repeaters"), single-shot designs have no moving parts other than the trigger, hammer/firing pin or frizzen, and therefore do not need a sizable receiver behind the barrel to accommodate a moving action, making them far less complex and more robust than revolvers or magazine/belt-fed firearms, but also with much slower rates of fire.
In firearms terminology, an action is the functional mechanism of a breech-loading firearm that handles the ammunition cartridges, or the method by which that mechanism works. Actions are technically not present on muzzleloaders, as all those are single-shot firearms with a closed off breech with the powder and projectile manually loaded from the muzzle. Instead, the muzzleloader ignition mechanism is referred to as the lock.
The Mossberg 500 (M500) is a series of pump action shotguns manufactured by O.F. Mossberg & Sons. The 500 series comprises widely varying models of hammerless repeaters, all of which share the same basic receiver and action, but differ in bore size, barrel length, choke options, magazine capacity, stock and forearm materials. Model numbers included in the 500 series are the 500, 505, 510, 535, and 590. The Revelation 310 and the New Haven 600 were also variations of the 500 series produced by Mossberg under different names. By 2021, 11,000,000 M500s had been produced, making it the most-produced shotgun of all time.
Pump action is a type of manual firearm action that is operated by moving a sliding handguard on the gun's forestock. When shooting, the sliding forend is pulled rearward to eject any expended cartridge and typically to cock the hammer or striker, and then pushed forward to load a new cartridge into the chamber. Most pump-action firearms use an integral tubular magazine, although some do use detachable box magazines. Pump-action firearms are typically associated with shotguns, although it has been used in rifles, grenade launchers, as well as other types of firearms. A firearm using this operating mechanism is colloquially referred to as a pumpgun.
A shotgun shell, shotshell, or shell is a type of rimmed, cylindrical (straight-walled) cartridges used specifically in shotguns, and is typically loaded with numerous small, pellet-like spherical sub-projectiles called shot, fired through a smoothbore barrel with a tapered constriction at the muzzle to regulate the extent of scattering. A shell can sometimes also contain only a single large solid projectile known as a slug. The hull usually consists of a paper or plastic tube often covered at the base by a metallic head cover which retains a primer, and the shot charge is typically contained by a wadding/sabot inside the case. The caliber of the shotshell is known as its gauge.
The .410 bore (10.4 mm) is one of the smallest caliber of shotgun shell commonly available. A .410 bore shotgun loaded with shot shells is well suited for small game hunting and pest control. The .410 started off in the United Kingdom as a garden gun along with the .360 and the No. 3 bore (9 mm) rimfire, No. 2 bore (7 mm) rimfire, and No. 1 bore (6 mm) rimfire. .410 shells have similar base dimensions to the .45 Colt cartridge, allowing many single-shot firearms, as well as derringers and revolvers chambered in that caliber, to fire .410 shot shells without any modifications.
The Saiga-12 is a shotgun available in a wide range of configurations, patterned after the Kalashnikov series of rifles and named after the Saiga antelope native to Russia. Like the Kalashnikov rifle variants, it is a rotating bolt, long-stroke gas piston operated firearm that feeds from a square magazine. All Saiga-12 configurations are recognizable as Kalashnikov-pattern guns by the large lever-safety on the right side of the receiver, the optic mounting rail on the left side of the receiver and the large top-mounted dust cover held in place by the rear of the recoil spring assembly. Saiga firearms are meant for civilian domestic sale in Russia, and export to international markets.
In breechloading firearms, an extractor is an action component that serves to remove spent casings of previously fired cartridges from the chamber, in order to vacate the chamber for loading a fresh round of ammunition.
A caliber conversion sleeve or adapter sleeve is a device which can be used to non-permanently alter a firearm to allow it to fire a different cartridge than the one it was originally designed to fire. The different cartridge must be smaller in some dimensions than the original design cartridge, and since smaller cartridges are usually cheaper, the device allows less expensive fire practice.
The Browning Automatic 5, most often Auto-5 or simply A-5, is a recoil-operated semi-automatic shotgun designed by John Browning and manufactured by Fabrique Nationale de Herstal. It was the first successful semi-automatic shotgun design, and remained in production until 1998. The name of the shotgun designates that it is an autoloader with a capacity of five rounds, four in the magazine and one in the chamber. Remington Arms and Savage Arms sold variants called the Remington Model 11 and Savage Model 720 that were nearly identical but lacked the magazine cutoff found on the Browning.
Break action is a type of firearm action in which the barrel(s) are hinged much like a door and rotate perpendicularly to the bore axis to expose the breech and allow loading and unloading of cartridges. A separate operation may be required for the cocking of a hammer to fire the new round. There are many types of break-action firearms; break actions are universal in double-barreled shotguns, double-barreled rifles, combination guns, and are commonly found in single shot pistols, rifles, shotguns, including flare guns, grenade launchers, air guns, and some older revolver designs. They are also known as hinge-action, break-open, break-barrel, break-top, or, on old revolvers, top-break actions.
The Browning Citori is an over-under double-barreled shotgun. It is marketed and distributed by the Browning Arms Company in Morgan, Utah, and manufactured for Browning by the Miroku Corporation in Nangoku, Japan.
The Remington Model 11-48 is a semi-automatic shotgun manufactured by Remington Arms as the first of its "new generation" semi-automatics produced after World War II. Released as the replacement for the Remington Model 11, it was manufactured from 1949 to 1968 and was produced in 12, 16, 20 and 28 gauge and .410 variations.

Colt Defender Mark I was an American multi-barreled shotgun intended for law enforcement or military use, completed in 1967. The shotgun was essentially a volley gun with eight single-shot barrels — each chambered for the 20-gauge 3-inch magnum shell — arranged in a octagonal fashion around the central axis, and could fire eight individual times like a semi-automatic action without the complexity of actually being a semi-automatic firearm. The action ran on a revolver-like rotating striker mechanism. The gun had a detachable buttstock and a pistol grip with a double-action trigger, and had a separate foregrip up front for instinctive shooting.
Recoil operation is an operating mechanism used to implement locked-breech autoloading firearms. Recoil operated firearms use the energy of recoil to cycle the action, as opposed to gas operation or blowback operation using the pressure of the propellant gas.
The Vepr-12 is a multipurpose semi-automatic detachable-magazine shotgun, produced by Molot-Oruzhie Ltd. It is patterned after the original Kalashnikov rifle and built on the heavier RPK light machine gun receiver.
The Hawk Industries Type 97 is the factory and official Chinese military and police designation of a shotgun design patterned after the Remington Model 870, and manufactured by Hawk Industries, a division of the China North Industries Corporation. The Type 97 is the base designation attributed to a variety of models with multiple configurations to suit different purposes and applications.
