Sawed-off Shotgun - Police and Military Use

Police and Military Use

Historical military use of sawed-off shotguns includes use as a primary weapon for Confederate cavalry during the American Civil War. These muzzle-loaded weapons were used primarily for close-range combat and to supplement the availability of more traditional short ranged weapons such as the saber or carbine. The availability of the source weapons and the ability to use single ball, shot, or a mix of both as the situation required were reasons why they were initially desired by those establishing Confederate cavalry units. They were replaced over time as more conventional arms became available and as the tactical use of cavalry shifted towards use as mounted infantry.

In modern usage, minimum length and barrel length restrictions only apply to civilian use; military and police departments may issue short-barreled shotguns, and major manufacturers offer special models with barrels in the range of 10 to 14 inches (25 to 36 cm) as riot shotguns or combat shotguns for use in areas with restricted space. These are generally referred to as "entry shotguns", because they are generally used for entering buildings, where the short easy handling is more important than the increased ammunition capacity of a longer shotgun. Breaching rounds provide another use for very short shotguns. These rounds are usually made of sintered powdered metal, but a normal buckshot or bird shot round will also work. A shotgun is used for breaching by placing the gun next to a door lock (0 to 2 inches away, 0 to 5 cm), and firing at a 45 degrees downward angle through the door between the lock or latch and the door frame. The impact of the projectile(s) opens a hole through the door, removing the latch or locking bolt. When through the door, the shot or sintered metal disperses quickly, and because it was aimed downwards, the risk of harming occupants on the other side of the breached door is minimized. Breaching guns used by police and the military may have barrels as short as 10 inches (25 cm), and they often have only a pistol grip rather than a full butt stock. Some models use a special cup-like muzzle extension to further minimize the risk of debris injuring the shooter. Because few rounds are fired, any sporting shotgun with a 3 round capacity could be shortened and used as a capable breaching shotgun.
