Good day guys. I would just like to find out if this is a mechanic or a bug. When reloading my shotgun it only reloads one bullet i have to then press triangle again for the rest to reload. Its very frustrating especially when its one of my primary weapons
Welcome to the forum @H3llion. 
The 12G Pump Shotgun works fine for me on PS4, but I had that particular problem with the Sjoqvist Semi-Auto.
