Quail and dove? Benelli M2 20 ga. It'll even kill pheasants and grouse if you get into them. Heck, with the right ammo, even waterfowl isn't out of the question. If you're on a budget, the Rem 870 is about as "do it all" as they come. But if I were you, I'd just borrow your sons 390 and go hunting.
