I recently bought a Mod. 640 nd S&W that has been shot very little. The trigger pull is pretty stiff, should I change springs or will is get better with range time and dry firing? Thanks in advance for help with this.
When I have put wolf springs in my s&w's I just changed the trigger spring and original or standard weight wolf hammer spring. This gets them in the 3 - 3 1/2 lb range without worrying about light primer strikes.
