A short-barrelled shotgun (SBS), also called a scattergun, shorty, or boom stick, is a type of shotgun with a shorter gun barrel—typically under 18 inches (46 cm)—and often a pistol grip instead of a longer shoulder stock. When shortened by cutting with a saw, these are colloquially termed sawn-off shotguns or sawed-off shotguns. Barrels can be manufactured at shorter lengths as an alternative to traditional, longer barrels. This makes them easier to transport and conceal due to their smaller profile and lighter weight. The design also makes the weapon more portable when maneuvering in confined spaces and for that reason law enforcement and military personnel find it useful in close-quarters combat scenarios. As a result of the shorter barrel length, any shotgun with a tubular magazine will have a reduction in its magazine capacity.
