You are right and you are wrong. It is just like knives, do you need a 10" Rambo or a practical 4" Mora? Individual perceptions, experience and tastes dictate choices.
Myself in a bunch of bad guys senario, I would like a Browning .50 cal MG, guess I will never have one, so I need to avoid crowds of bad guys. None of my single action revolvers will be very effective, except for the first 5 "subjects".
