If you use other mods that affect levelled lists, you may need to make a merged leveled lists patch using FO4Edit. A good tutorial on how to do
this can be found here.

September Update Version 3
Adds the ability to make longer barrels for all guns for better accuracy and range.

Update Jule 30th Version 2
So first thing is important. As I've now incorporated the Double Barrel Shotgun into the shared stock/grips and sights that all my shotguns share, this will require a save where this mod isn't loaded. So simply uninstall the old version, then make a new save, then load the new version. If you don't then there will be missing stocks and sights and adding them will require a complete rebuild of the gun piece by piece at the weapons workbench.
This version also adds in 2 new stock options, which is synthetic and bone. It also increases the damage of all the shotguns slightly and gives the SIngle Shotgun its own aim model, making it more accurate.
This means that this mod will not be compatible with any other mod that alters the DB shotgun, the stocks or the sights.


Update July 7th
Removed AWKCR dependency and weapons added to Levelled lists thanks to trevor11004.
Adds Revolver Shotgun (4 shot) still needs a bit of work but functions pretty much as intended. When viewed in 3rd person, this gun is bordering on clownish looking because it's pretty big.


Adds 3 New shotguns to the game: The Single Shotgun, the Caravan Shotgun and the Triple-Barrel Shotgun. All modifiable.
All of them are modified vanilla double barrel meshes and I have tried to make them look and feel as though they could have come with the game.

In the future I am hoping to add them to level lists (and remove the AWKCR requirement) but I'm unsure how to do that and also how to do it without conflicts with other mods that alter the lists. Any help with that would be appreciated.

Known Issue: In 3rd person, the single shotgun animation shows the PC doing the movements of putting in 2 shells, this is not something I can fix.
