It's already been said, but you can't go wrong with a youth Remington 870. My dad got me one when I was 12. Has the 21" barrel and is an awesome little gun for dove/quail, and I've killed my share of pheasants with it. When I was 14 dad got me a full size stock for it. 23 years later and I still use it, but hopefully in about 6-7 years I'll hand it off to my son.
