    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.

    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.

    J-Frame

    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
