remington 870 pump in the version you can afford.. my son is 18 last month and has shot two deer, geese and ducks with his express.. youll need screw in chokes with the game youve listed.. autos reduce recoil but need to be cleaned well, and wont function well withligt loads and will cost more.. several years ago a friend of mines mosberg chokes would not pattern to point of impact correctly.. my sons 870 had ejection problems and we took it to a reminton authorized gunsmith in your town, got it back quicly and have no more problems with it.. some makes may need to go back to the factory.. i never shot a 3 1/2 inch but if i was to get one id get the auto.. as thier heavier and will reduce recoil for that, and the auto feature will also reduce recoil.. but im guessing they will be out of your price range.. .. . good luck, dave..
