The Definition of Double-Barreled Shotgun
A shotgun with two barrels, usually of the same gauge or bore.
The two types of double-barreled shotguns are over/under (abbreviated as O/U or OU),
in which the two barrels are stacked on top of each other, and side-by-side (abbreviated as SxS),
in which the two barrels sit beside each other. See photo at right for example of side-by-side double-barreled shotgun.
For double-barreled guns that use one shotgun barrel and one rifle barrel, see combination gun.
