    TECH TIP: SHIM INSTALLATION

    S&W Hammer and Trigger Shim Installation Instructions

    To install shims in your S&W Revolver, you should disassemble and remove the Hammer and Trigger springs,
    begin by installing a shim on each side of the Trigger and Hammer, re-install the frame side plate (without springs) and check for binding. If the Trigger and Hammer move freely, continue to add shims.
    At the point you begin to trap or bind the hammer and trigger, you will have your approximate free clearance, and you can then remove shims and install the proper amount, leaving a final clearance of around .003" to .004" - and reassemble the unit complete.

    I suggest a 12 Piece Kit to provide ample Shims for this procedure.

    Smith & Wesson Models K, L and N Shooter's Pak #17121

    Wolff 17121
    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. NOTE: For most target and non-critical applications, Wolff recommends the TYPE-2 spring which is reduced power.
    This kit is the TYPE 2
    For critical applications such as law enforcement, Wolff strongly recommends the TYPE-1 spring which is factory equivalent in strength.
    Power Rib Shooter's Paks -

    Shooter's paks for Smith & Wesson K, L and N frame revolvers contain a Power Rib mainspring and 1 each of 13, 14 and 15 pound reduced power rebound springs allowing optimum adjustment of the hammer and trigger functions. As mentioned above, these paks can often take the place of expensive "trigger jobs" with better results

    SMITHMASTER™
    TRIGGER SPRING TOOL FOR S&W® REVOLVERS

    SMITHMASTER™ - TRIGGER SPRING TOOL FOR S&W® REVOLVERS

    Have you ever experienced a Smith and Wesson® trigger spring flying past your eyeball, on it's way to heaven know's where ? Or perhaps you've jammed a makeshift tool into your hand while trying to install a S&W® trigger spring and rebound? Not a fun thing! Anyone who's worked on S&W's most likely has a memory or two of flying springs!

    The SmithMaster™ takes the worry out of changing S&W® Trigger springs. Works on all J,K,L, and N Frame revolvers.

    The SmithMaster™ is a unique, double ended tool designed for easy, trouble free removal and installation of the S&W® rebound/triggerspring assembly. One end of the tool allows CONTROLLED REMOVAL of the rebound/trigger spring.

    The other end allows CONTROLLED INSTALLATION, the trickiest part of the whole operation. No more trigger springs flying out and getting lost! The Smithmaster™ completely controls the spring, for worry free installation. Great for routine maintenance, and trigger jobs; especially usefull for trying different weight aftermarket trigger return springs, for a lighter, smoother trigger pull

    Man sized Delrin main body/handle has deep "Gripper Grooves" for sure control. Removal and installation tool heads are hardened tool steel for long life, and are coated to prevent frame marring. Approx. 8" OAL. Very Thorough Instructions included.

    It's the finest trigger spring tool ever made for S&W® Revolvers!
    There is nothing that compares to it!

    "This Spring Tool is a Must-Have to change the Trigger Spring on S&W K, L, N and J Frame Revolvers, Makes Disassembly and Reassembly a Breeze, Well Made and Worth Every Penny!"

    Lance, I received my order today and had to give the S&W rebound slide/spring tool a try. Wow is that easy. I was skeptical that it would be that easy. But after watching the video on your webpage I thought it was worth a try. Sure enough, no more wrestling on the bench with that little devil.
