How it works
IGN states that the Long Barrel increases the shotgun’s ammunition capacity to eight and adds one box to its inventory size. It is found at Gun Shop Kendo after leaving the Parking Garage and heading to the streets behind the R.P.D. This source describes the capacity and inventory effects; it does not quantify any accuracy change.
