Double-barrel shotgun (Fallout 4)

The double-barrel shotgun is a weapon in Fallout 4.

Characteristics
The double-barrel Shotgun is a break-action two-handed weapon that uses Shotgun Shells as ammunition. Intended for use at close range, the double-barrel Shotgun deals impressive damage and is useful against any enemy that must close distance to attack. *Needs verifying*

Later modifications will increase its damage in line with more advanced weapons and also modify its range, accuracy, and recoil.

The biggest downside to this weapon is the low ammunition capacity of two shells, and it cannot be upgraded to hold more. This means frequent and somewhat-lengthy reload times, thus lowering the weapon's effectiveness against large groups of weaker enemies.

Weapon modifications

 * A sawed-off barrel can be added to the weapon, reducing range and increasing spread but also improving critical hit damage.
 * A longer barrel can be added to the weapon, narrowing spread and increasing range.
 * Night sights can be added onto the weapon
 * A reflex sight (red) can be added to the weapon

Variants
Unique "Never Ending double-barrel shotgun": with this variant you never have to reload, completely negating the biggest downside of the double barrel shotgun. However you still consume ammo and can still run out.

Locations
The double-barrel shotgun is a fairly common firearm, becoming available early in the game. They can be found on low level Raiders, some Settlers (rarely), or potentially part of stock for purchase from any vendor that can sell weapons.
