Mossberg 590 pump-action riot shotgun, with 20 inch barrel

A riot shotgun is a shotgun designed or modified for use as a primarily defensive weapon, primarily by the use of a short barrel.[1][2] The riot shotgun is used military personnel for riot control or guard duty, and is commonly used as a patrol weapon by law enfrocement personnel, as well as a home defense weapon by private citizens.[3][4] For offensive military shotgun use, see combat shotgun.

Characteristics

The primary characteristic of a riot shotgun is a "short" barrel (generally 14", 18-18.5", or 20" in length) which makes the shotgun more compact and easy to handle, easier to store inside a police vehicle, and more suitable for quickly aiming at stationary targets. Generally they have an open choke, to cause the shot to spread quickly, and they may be equipped with bead, rifle, or ghost-ring sights. The ability to use slugs extends the range and penetration capability of the shotgun. Police officers commonly secure a shotgun in their vehicles to supplement their handgun, if greater firepower is needed. The barrel of a firearm is the tube, usually metal, through which a controlled explosion is released in order to propel a projectile out of the end at great speed. ...

The multiple projectile ability of a shotgun greatly increases the probability of a hit on an assailant, and the multiple projectiles increase the likelihood of a disabling hit. A typical police load would be a 12-gauge 2 3/4-inch (70 mm) 00 ("double-aught") buckshot shell consists of 9 .33 caliber (8.5 mm) round balls, each of which is similar in size and velocity to a lightweight handgun bullet. This shot spreads out to a greater or lesser degree depending on the barrel choke, and can be effective at ranges as far as 75 yards (70 m). The delivery of the large number of projectiles simultaneously makes the shotgun the most effective short range weapon commonly used, with a hit probability 45% greater than a submachine gun, and twice as great as an assault rifle.[5] It has been suggested that Lead shot, Shotgun slug, Slug (projectile), Brenneke slug, Foster slug, specialty shotgun amunition, Flexible baton round, Breaching round, Bolo Shell, Dragons Breath, R.I.P. cartridge, Rat-shot be merged into this article or section. ...

Riot vs. combat shotguns

The division between the riot shotgun and the combat shotgun is blurry, and may be more a matter of application than design. A combat shotgun would be used in military combat situations as a primarily offensive weapon, where a riot shotgun would be used in law enforcement or civilian situations as a primarily defensive weapon. Common additions to a combat shotgun would be provision for attaching a bayonet, and the addition of a ventilated heat shield over the barrel to prevent the operator's fingers from being burned by a hot barrel (during extended gunfights). For other uses, see bayonet (disambiguation). ...


Riot shotguns are also more limited in range than combat shotguns by the nature of their use. A combat shotgun is considered effective out to 75 yards (70 m) because on average at least 1 pellet of a 9 pellet 00 buckshot load will hit a human sized target at that range. This is enough to degrade the combat effectiveness of an enemy soldier, but it is not enough to reliably disable an assailant in a defensive situation. For that, there must be multiple hits to the target, enough that one or more pellets will hit a vital region. Generally this is well under 40 yards (37 metres) with a cylinder bore barrel. Beyond this range, slugs and good iron sights are recommended, extending the range to over 100 meters.[5][6] Looking down the iron sight of an ArmaLite M15A4 Carbine (a civilian copy of the M4 Carbine) Rear diopter-type iron sight of an Rk 62 assault rifle. ...


Entry shotguns

The entry shotgun is a further modified riot shotgun with an extremely short barrel and often only a pistol grip rather than a buttstock. It is often used with breaching rounds, as its extremely short length is ideal for quickly disabling locks and entering the forced door. Since entry shotguns would in most areas be classified as short barrelled shotguns, legally equivalent to illegally modified sawed-off shotguns (even though they are manufactured at that length, and not literally "sawed off"), they are highly restricted under gun control laws such as the National Firearms Act and generally only used by police and military. A breaching round is a shotgun shell which is designed to blow off the hinges of a door without harming the operator or the occupants of the room to be entered. ...

Shotguns have also been referred to as "scatterguns", "fowling pieces" or "two-shoot guns" historically, and were used as a replacement for the blunderbuss.
Shotguns made for close ranges, where the angular speed of the targets is great (such as skeet shooting, or upland bird hunting) tend to have shorter barrels, around 24 to 28 inches (610 to 710 mm).
Shotguns used by military, police, and other government agencies are exempted from regulation under the National Firearms Act of 1934, and often have barrels as short as 12 to 14 inches (305 to 356 mm), so that they are easier to handle in confined spaces.
