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 27 yards (25 meters) with a cylinder bore barrel. Beyond this range, slugs and good iron sights are recommended, extending the range to over 109 yards (100 meters). Less lethal alternatives The latter part of the 20th century saw a new role for the riot shotgun, with the advent of a wide variety of less lethal ammunition for police use. These vary from the early "bean bag" shooting flexible baton rounds, rubber bullets and other impact munitions, to tear gas and, released in October 2009, a 12 gauge electroshock weapon from TASER International. Using the shotgun as the delivery system allows the officers to quickly choose a lethal or a less lethal weapon, so responding officers can adapt to changing situations. An officer in a standoff can quickly eject a chambered buckshot cartridge and replace it with a less-lethal cartridge such as a bean bag, and is not required to unload the magazine as with most rifles or handguns. Alternatively, one officer can be equipped with less lethal munitions, while others, equipped with buckshot, can provide a backup in case the less lethal rounds fail to stop the target. Entry and breaching shotguns The entry shotgun or breaching shotgun is a role that can be filled by a standard riot shotgun, or one further modified for these purposes. They may have an extremely short barrel (14" or less) and often only a pistol grip rather than a buttstock, or a folding or collapsing buttstock if it is provided with one. In addition, the barrel often has a muzzle brake, used to disperse hot gases rearward, in order to reduce recoil. This type of shotgun is often used to fire special breaching rounds which are designed to disable or destroy door latches while limiting overpenetration of the projectiles used beyond the door. Since these shotguns would in some areas be classified as short barreled shotguns, they are often highly restricted under gun control laws and generally only used by police and military, except in some regions such as the USA. Usage In 2006, during anti-corruption protests in Budapest (Hungary) some people were hit on the head by shotgun-fired bean bag rounds. At least 3 of them were blinded.
