I am intrigued by these guns mainly in 455 Webley. I noticed on handling one that the cylinder rotates freely even when it is closed. The shop owner said that is normal for them as they only lock up when the gun is cocked. Is that true? If so, what happens if after firing a shot, you may bump the cylinder and have say 3 rounds fired and 3 unfired. If you bump it, you may get a click instead of a bang when pulling the trigger. It's not a big deal at the range, but if you are fighting for your life, that could be a problem.
