I know whacking the cylinder in and out of the frame like 1940s detetives and slaming the trigger back as hard as you can is abusive, but whenever I let my friends use any of my revolver at the range they use single action by snaping back the hammer back where it sounds like one large CLUMP. I can pull it back as quick as I can without doing that. What they are doing almost goes out of the way to snap it back. Obviously snapping the hammer back with a sling of your wrist where it goes CLACK!!! is abusive but in y'all's opinion what is the boundary between quick SA on a DA revolver and abusive treatment
