So basically the other mods that do the "same" thing make it some sort of a weird burst mode or whatever and this seemed like the obvious solution to do this.
This mod adds a weapon modification for double barreled shotguns in the base game that doubles the damage and halves the mag size.
So it's effectively the same as if you fired both barrels, consuming two shells of ammo.
Known issues:
The Claire 12G shotgun (the secondary double barrel) has reaaally bad ammo pickup. That's because the base game pickup for it is already shit. Bother Overkill, not me.
