SMITH & WESSON K, L & N FRAME REVOLVERS

The Powerib Mainspring

 

U.S. Patent No. 4,693,027

The Power Rib Mainspring developed by W.C. Wolff Company is a patented mainspring for use in Smith & Wesson K, L and N frame revolvers. This spring has a unique variable power rib-back design. The Wolff Power Rib Mainspring dramatically improves the smoothness and consistency of trigger pull essentially eliminating stack up as well as providing optimum hammer action. This spring can usually take the place of expensive trigger jobs, with better results. For most target and non-critical applications, we recommend the TYPE-2 spring which is reduced power. For critical applications such as law enforcement, we strongly recommend the TYPE-1 spring which is factory equivalent in strength.
