Big Improvement on S&W spring 19/10/2017
My new S&W 686 SA trigger pull measured just over 5lbs on my RCBS trigger pull gauge, which was too heavy (for me) for bullseye shooting. Installing the Wilson mainspring and 12lb trigger return spring reduced the SA pull to 3.5lbs which I'm much happier with. This is with the mainspring tension screw fully home. Also, the DA pull feels much lighter and smoother, but 'm unable to measure this as my RCBS scale bottoms out at 8lbs.

Big improvement, no problems 01/05/2017
Installation was quick and simple in my 686+.
I installed the 14# spring. The double action pull is much easier and smoother.
Fired PMC Bronze and Federal Premium, in 38+p and 357. I had no issues with light strikes.
