Wow. Lots of really nice pictures in this thread.
I have a USFA Rodeo (the first edition, there's a Rodeo II out now). I really like it. It's in .45 Colt and has a case-colored hammer. It has a 5.5" barrel.
I don't have any pics, but it looks just like USFA's pics, only with a blued-looking hammer. The hammer bluing is not deep (see below).
I'm relatively inexperienced (only been shootin' about six months
), but it seems pretty accurate and is a lot of fun to shoot. The trigger is pretty light and has almost no creep. The matte black finish is durable and not ugly (but not pretty). The cylinder has yet to show any drag marks, and locks up tight at full-cock.
The hammer is showing some slight finish wear on the sides due to dragging, but that's the worst thing I can say about the gun.
Now that their "Premium" SA prices are so low, I would definitely recommend spending the extra for the blue finish, if that's your cup of tea. Those guns are beautiful.
