It can accept the Hunting Shotgun choke mod, but not the extended magazine tube. The strength requirement to use it is also slightly lower. Gameplay-wise, this gun's stats are cloned directly from the Hunting Shotgun, except that it only holds 4 rounds, has a greater spread, lighter weight, and shorter range. Lastly, I added the sling swivel from the Service Rifle to the front of the magazine tube. I then removed the rear portion of the stock and stitched the faces together to make the pistol grip.
I used the vanilla Hunting Shotgun as a base and shortened the barrel and magazine tube. In this mod, I tried to capture that sensation and let you live out your badass pirate fantasies. There's the visceral boom when you pull the trigger and it bucks in your hands, filling the air with the intoxicating scent of cordite, and then the smooth rattle of oiled metal gliding over itself as you rack the pump and chamber another round. There's just something incredibly badass about a short-barreled shotgun with a pistol grip that makes you feel like a pirate or something. Ain't a lot of folk gonna be too happy if he has to speak up.' Y'all play your cards right, he stays silent.
