I LIKE A LIGHT TRIGGER PULL ON MY S&W REVOLVERS, AND USUALLY REPLACE THE FACTORY REBOUND WITH A LIGHTER SPRING. WOLF HAS RECENTLY STARTED SELLING AN 11 POUND REBOUND SPRING FOR THE S&W REVOLVER. DOES ANYONE KNOW HOW LIGHT A SPRING IS ACCEPTABLE TO USE WITHOUT AFFECTING RELIABILITY ? I KEEP IT CLEAN UNDER THE SIDE PLATE, AND HAVE NEVER HAD A TRIGGER REBOUND PROBLEM WITH A 13 POUND SPRING. I HAVE BEEN TOLD THAT THE FACTORY SPRING IS 18 POUND.
