Trench Gun (5e Equipment)
From D&D Wiki
Martial Ranged Weapons
Yet another classic invention of the First World War, trench guns are pump-action shotguns designed for military use before the invention of modern automatic shotguns, particularly within the war's distinctive trenches. Meant for close quarters, they make up for their lack of range with raw damage output due to how fluidly their actions can be cycled by a skilled user.
When you make an attack with this weapon, you may make it a slamfire attack instead. A slamfire attack expends two rounds of ammunition and has its range reduced to 10/40, but you may roll for damage twice, adding both results to the attack's total damage.
