Add a refitted barrel attachment to Shotguns that allows them to fire slugs. Since the "rounds" category has been removed from the arsenal and its unsure if its ever coming back, why not give these poor poor Shotguns their much-deserved slugs via a new barrel slot attachment instead? They barely have any attachments right now so a new one would help them out greatly! It could also be a magazine slot attachment which would make more sense but then itd get in the way of extended mag and ehhhh i really like my extended mag
