What's your budget?
Will you ever use it for anything but deer? If so, what else?
I'd suggest a Remington 870 or a Mossberg 500, depending on your budget............
Either will allow you pleanty of after-market add-ons and in some cases you can get a good deal on combo set-ups...i.e. slug barrel and screw in choke barrel in a package.
Cheapest bet is a used Mossberg 500 combo set-up...
Buy more if you can afford it
