The Pump Action Shotgun is the series' bread-and-butter close-range gun, built here on the Mossberg 590 by Shrewsbury. You get heavy stopping power at short distance in exchange for a slow, shell-by-shell reload. It has been a staple since the early games and works best clearing rooms or dealing with a crowd before they close in.
A shotgun like this usually comes from Ammu-Nation once you have the cash, or gets picked up off downed enemies who carry one. Rockstar has not confirmed GTA 6 gun store details, so treat the store route as the likely one for now.
