I've put maybe 1500 rounds through my 686 and dry fired it an additional 1500 times. I was cleaning it today with a brush to get some carbon build up out of the frame window when I noticed the 'ratchet' teeth, for lack of the proper technical term, were damaged. I compared to my recently partially rebuilt 629 and my 19 and they have zilch observable wear on their teeth (albeit with less rounds and dry firing).
Photo is a bit blurry but the shiny spots show where the metal is worn and there are some raised burrs. Damage seems to go from almost none at 3 o'clockish to the worst at the opposite ratchet at 9 o'clockish.
