To be a little more specific than Rebel Hog, I would recommend a 20 ga Browning Gold Superlight w/ 26" barrel. Weight makes a huge difference when you are carrying around chasing birds.

If you plan on doing any waterfowl, get the 12 ga Superlight w/ 26" barrel. That is what I would buy if I didn't already have a Citori 12 and a3 1/2" Gold. In my opinion, the 3 1/2" is unnecessary, but at the time I bought it, that is what I wanted. Since then, I bought my son a 3" Gold w/ 26" barrel.
