Pretty simple: Mossberg 500, Maverick 88 (which is a 500 with safety relocated to a better location) or Remington 870. Any of these three shotguns will do just about anything you could ever want them to, from being competent trap guns, faithful hunting guns to tactical shotguns, all with the swap of a choke (or barrel to go from trap to tactical) and maybe a few accessories if you want.
