    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.

    Just to let you know, I installed your .003”cylinder shim in my S&W 43C 22LR snub nose revolver with great results. I was getting almost 10% misfires. After eliminating endshake I had one misfire from 150 rounds of the same batch of ammo. Thanks, Charles

    Hello Lance, I just wanted to say I am very pleased with this kit I recently purchased from you. I was able to fix the end-shake issue on my Smith and Wesson model 34-1 (.22 RF J-Frame Kit Gun) I had previously taken this gun to a so-called "gunsmith" who told me my gun was just "worn out" and unrepairable, but by using your end-shake shims it was restored to proper function. Your kit fixed my gun for $10.00, I am an extremely satisfied customer.

    Hi Lance,
    I installed the shims in the J-frame last night—unfortunately it won’t accept the right-side hammer shim because the transfer bar is too close. (Am sure two would work fine with the hammerless models.)
    I just used a .006” shim on the left side only and it worked out fine. As with the SP101, I am well satisfied and amazed by the improvement.
    Dennis in NC

    Hi Lance, the Shim Kit is incredible!
    I can only assume that they are very difficult to make. Sure glad I found them. The trigger on my 31-1 was rubbing on the frame and one .003 shim took care of it.
    Well worth the price! Thanks again, Cliff in TX

    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!"
