Installed this spring kit in my 657. WOW!!! Went from a 12lb DA trigger to 7 1/2lb DA trigger. SA is at 3lbs 2oz. What a difference. I am using CCI large pistol primers and they go off every trigger pull. Very happy and will be ordering more for my other Smiths.
The conversion for my Smith and Wesson 686-3 was very nice and appears to function perfectly with dummy bullets and with laser strikeman system. I won't be able to get to the range for a few months, but it seems to function perfectly.
