I just picked up a new 686 6". The trigger is pretty smooth and consistent on the revolver but I have a question. When pulled DA it's not as bad but when pulled SA, I am getting a very hollow, ping, or tinty type sound when the hammer falls. Is this normal? I've not had another new revolver do this. The closest is when I put a Wolff mainspring in another revolver and it made this sound. I've checked the strain screw and it's tight. The revovler seems to function ok, it's just the strange noise. Any help? Thanks.
