Just about any shotgun that can shoot two rounds without reloading will do the trick. That's if you mean skeet and not trap, as starting with trap a single shot will do. "Fit" of the gun matters more with clays than it does with game, or so has been my experience. Did I do it again, I'd borrow a gun and see how I like the sport before buying a gun for the purpose. (I had/have an 870, so started with that, bought a Browning Citori a couple years later.)

Trap and skeet shooters are a remarkable bunch, you'll be offered opportunities to shoot a wide range of guns once you show a bit of interest. After all, they like competition, the more the merrier.

Watch it, it is highly addictive. Once bit, you'll never quit.
