As for those 7 or 8 shot revolvers...they scare me. Spent too many years with my 6 shot Model 19 Combat Magnum to ever feel comfortable with more rounds in a wheel gun. I would likely shoot six and reload.
No need to be frightened. If six rounds are plenty to survive a "typical" gun fight, there'd be no reason to reload in the first place. So that seventh unfired round that got dumped inadvertently would be like teats on a boar hog. Unless, of course, the gun fight you found yourself in proved to be atypical
