CAS

The bolt/cylinder stop is not engaged, but the hand/pawl will rotate the cylinder.

Ruger Vaqueros and Blackhawks use a transfer bar ignition system, so it is perfectly safe to carry six in the cylinder. However, it is never allowed in CAS competition.

Well, I do not go often but a lot of our stages require a 1-2-3 and then a 3-2-1 shot pattern you cannot accomplish that with ten rounds.

That would require an on-the-clock reload.

As far as your original question, I highly recommend the Ruger Vaqueros. They're practically indestructible and can be slicked up easily if you're so inclined. I have several pairs, both Old Models and New Models, and I love 'em all.

You can indeed carry a single-action revolver as a concealed gun. Mernickle makes a great holster for it.
