Lightening a main and trigger spring is not always the best solution for trigger pull reduction and can some times lead to misfires and hammer blow back. Usually the best route is to first check engagement interfaces to make sure they are square and plum with each other. There should be no hammer movement at all before the sear disengagement from full cock regardless of what you hear.I have a pistol which has a wildly heavy trigger. Has to be more than 20 lbs. The lock is pictured. Which spring needs to be adjusted in order to lower the trigger pull weight?
My guess from your description is the sear and full cock notch need to be stoned square and plumb to each other and the edge broke to finish up. If the angle of engagement is to acute then the sear has to push the hammer back to release from full cock and if off angle in the opposite direction than the gun can be pushed or bumped off from full cock. If the angle is correct and full contact is made from side to side across the sear face then the hammer will not move through trigger let off and will not be able to be knocked off by impact.I took the advice that was tendered. It worked. Trigger down to about 8lbs. The gun is useful now.
Thank you for the advice.
