Double Barrels! shotguns have medium-high damage output and mediocre accuracy and recoil, with a fairly broad spread which limits them to medium range at maximum, though they are not as limited as the triple and quad barrel shotguns.
Like most Tediore weapons, a Double Barrels! is thrown forward when reloaded, with any rounds left in the magazine being lost but adding significantly to the damage from the explosion. The weapon will bounce a few times like a Lobbed grenade if it does not hit anything, but will explode instantly on contact with an enemy. Typically a Double Barrels! will have three or more shots between reloads, which provides them with excellent damage-dealing capabilities if reloaded early.
