What is the Double Barrel shotgun?

A two-shell break-action shotgun for close range. It fires one barrel at a time, six pellets per shot, and reloads by breaking the gun open and putting shells back in.

It's researched at the workbench and crafted like any other weapon.

It hits hard at point-blank range and falls off quickly with distance — it's a weapon for corridors and doorways, not for open ground. With only two shells before a reload, the reload itself is the risk: plan where you'll be standing when it happens.
