I have not had time to read all in this thread will come back to it. Just a point or two on Semi V revolver. Wheel guns do fuck up. I have had a couple of S&W in 38 fail to fire, fail to index correctly. Might have been maintenance, I don't know. Also one test run by a shooting magazine had numerous semi autos and one S&W. They claim the Revolver did not stuff up but it did. A fail to fire for any reason was a stuff up. In this case it was due to grit slowing the hammer down to the extent it did not strike the primer hard enough. The 3 that had no failures, Colt 1911, Browning Hi Power and Glock. They did not have a CZ75 in the test.

To me the big advantage of the wheel gun is, fail to fire pull the trigger again and should fire do not need to rack it.
