Some very handsome guns in this thread.
For clays, I just put my 28" vent-rib barrel on my receiver with my police stock. I'll put on my +3 extension when I'm just screwing around, or leave it off for more formal club/competition settings where I'm only loading one or two shells at a time. For chokes, I use the basic flush Remington choke tubes; I don't shoot seriously enough to warrant shelling out for really high-end tubes.

I wouldn't mind finding a thumbhole stock like RainMan_JH's someday, but since I have large-ish hands, a lot of thumbhole/pistol-grip stocks put my trigger finger too far forward.
