You don't need a camo shotgun. But it sure is nice to not have to worry about beating up your blued & wood new toy.

The Benelli SBE III isn't a great choice for a deer slugger, but it'll do very well on wing game. However, it's a Cadillac, and frankly, at 15, unless you have an unlimited pool of daddy's money to spend, you'll likely be better served by buying a Remington 870 and getting your skill set up before you grow up and finances allow stepping up to a Benelli. Buy a used Rem 870 today, in 5-10yrs it'll be worth about as much as you pay for it now, to put towards your Benelli. However, my bet would say you'd keep it and ADD the Benelli, instead of replace with it.

I'm not a huge fan of the Mav 88, but it works. The 500 and 870 are better shotguns, and they're affordable enough, I wouldn't buy a Maverick.
