The biggest influence of trigger weight is the trigger return spring, not the mainspring. Replacing the #18 or above factory trigger return spring with a lighter one will not effect the hammer fall.
The various ribbed mainsprings only give a
slightlyreduced tension to pull the trigger back against while maintaining factory mainspring weight on the hammer. In fact I needed a trigger gauge to actually tell there was a difference. When I changed the trigger return spring I could
feel the difference immediately. (Wolff also make a reduced weight ribbed mainspring that they say is for competition use only and should not be used in a self defence handgun).
Even though I had a standard weight mainspring in my 686 I did end up with light primer strikes
when using SRP to ignite slow burning “rifle” powders. Even fitting a new Wolff mainspring did not fix that particular problem. (Obviously Federal SRP had gotten a bit harder over time
). What
did fix the problem was replacing the strain screw with an 8-32 X 1/2 UNC hex head screw and turning it a bit deeper into the grip frame while not adding to the double action feel.
One drawback has been that when shooting a 50 yard segment of a competition, I tend to shoot single action. Yesterday, after several months shooting only semi-auto’s and forgetting how my 686 trigger “feels” I shot my 686-4 at 50 yards and had 3 out of 6 shots go off a little before I was ready. The results were two 8’s at 12 o’clock and a 7 at 1 o’clock for a total of 53/60 for the target (shot prone. A bit more practice with the revolver will fix the early discharge, and really, no-one should be shooting a self defence revolver single action like that.
