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.

Our USA Made Shim Stock holds a tolerance of less than 10% while most all calipers hold a measurement tolerance of Plus or Minus .001" and many round to the nearest .0005"
Burrs from the stamping process can influance the measurements slightly, it is best to refer to the color coding when deciding what shim to use.

Spring Removal Tool Information at the Bottom of this Page
Wolff Reduced Power Spring Kit # 17121
Smith & Wesson Models K, L and N Shooter's Pak
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
I also include a 17185 Xtra Power Cylinder Stop Spring in this kit,
for a total of 5 springs in this kit.
K-Frame models: 10, 12, 13, 14, 15, 16, 17, 18, 19, 65, 66, 67, 617, 648
L-Frame models: 581, 586, 681, 686, 696

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.
Thank You, Ray in WI
