I went to my first clays shoot last week. I used a Norinco SXS coach gun in 12 ga. It beat the hell out of me with no recoil pad on the butt stock! I only got 39 out of 100, but then again, some of the clays were out there pretty far, and with that 20" barrel, I just don't think I had the same reach that a clays gun would have.
If you are really interested, I have an old Boito O/U 12 ga. I can sell you for $100 + shipping. They're not the best of clays guns, supposedly a little heavy for the sport. I'm actually selling it for a friend that is retired. They're not the prettiest guns out there, but is should get you going in the sport.
I actually forgot I had it in the closet, or I sould have taken it last week instead of a Cowboy Action Shotgun!
Oh, the two triggers, no big deal. Once you get used to it, it feels normal.
