Two Major Variants of Vaqueros Exist.
The Original Vaquero was marketed from 1993 until 2005, and was slightly larger than the Colt Single Action Army. The New Vaquero, (NV) produced from 2005 to the present is closer to the dimensions of the Colt Single Action Army.
The New Vaquero has a small frame and uses the 33250 / 33251 Kit.

Ruger New Model Single Action Video

New Model Ruger Single Action
Shim Kit Installation Video

Let me tell you about my Father-in-Laws Ruger Single Six.
It is a New Model Single Six .22 Cal, a very nice Revolver in Stainless, Pictured here.
Ruger New Single Six

The Trigger Pull as originally tested was inconsistent, varying from 3.75 lbs to 4.25 lbs. over the course of 6 pulls. This was a factory fresh gun with less than 100 rounds.
Using the Tear Down instructions in the Ruger Video on this page, I disassembled Dad's Ruger, installed a Wolff #17116 Reduced Power Shooters Pak and my RSA Shim Kit.
The results were very good to say the least, 6 pulls and a very consistent 2 lbs. 8 ozs.
Thats right, a nice 2 1/2 Pound Trigger Pull, with just an hour of your time, a Wolff RP Shooters Pak and a TriggerShims Brand RSA Shim kit.


Hammer Spring R&R Fixture
Hammer Spring R&R Fixture

There are Several Ways to Accomplish Removing and Reinstalling the Hammer Spring, but I wanted to Show the Simplist Method Possible Here.
Take a Small Block of Wood, You Could Even Use Your Bench Top, Drill a 3/16 Diameter by 3/8 Deep Hole to Anchor Your Hammer Strut, Grasp the Spring Firmly with Your Fingers and Push Down to Relive the Tension and Remove the Pin.
A Thin Leather Glove Helps, as Does Working Quickly.
When Reinstalling The Cross Pin, I Found that on Your First Attempt if You Just Get the Pin Half Way, That Will Allow You to Get a Better Grip, Making Installing It the Rest of the Way Eaiser.


Ruger Single Action Hammer and Trigger Shims
Installation Instructions

These shims are sized for all Ruger Single Action Revolvers (except the Bearcat)
They will work on most RSA clones.
General Instructions
Make Sure your Firearm is Unloaded!
It is important that you understand the factory instructions concerning disassembly of the Ruger Single Action Revolver as installing shims will require you to remove the Back Strap and Trigger Guard from the Frame.
Hammer Shims
Our shims installed on the left side of the hammer window will end the Hammer Rubbing the left side of the Frame. The Hammer Rubbing will affect the Power of the Hammer and
may account for Misfires when Lighter than Factory Hammer Spring is used.
You may find there is more room than necessary between the sides of the Hammer and
the inside of the Frame in the Hammer Pivot Area.
We Suggest that you Measure the Space on the Left Side of the Hammer (the side the Pawl Pivots On) between the Hammer and the Frame with a Feeler Gauge.
This will give you an idea of the proper amount of shims to be installed, making sure to allow
some space so no binding is evident.
The Left side is the only side the Large Hammer Shim will fit on some models.
Installing a Shim on the Left Side will move the Hammer to the Center and should solve the problem of the Hammer Rubbing the Upper Left Side and will take out much of the side play
in the Hammer.
To Install; Slide the Hammer Pivot Pin to the Right just enough to allow sliding the shim
in the space between the Hammer and the Frame. A small wooden pick is helpful, and the shims are easier to control with a drop of oil or grease on them to make them stick.
Trigger Shims
Trigger Shims can be installed by sliding the Trigger Pivot Pin out the Right Side just far enough to slide a shim in between the Cylinder Latch and the Trigger,
and making sure the shim is aligned, slide the Pivot Pin on into the Trigger, but not into the Frame, slide a shim between the Trigger and the Frame.
Now Align that Shim and the Trigger Pin can be fully installed and seated .
A dab of grease or oil on the shim will aid in installation, as will a small wooden pick to aid alignment.
Check again to make certain there is no binding and you are ready for reassembly.

A Letter from a Customer;

Hello Lance, The shims saved me a lot of pain on my NM Blackhawk. Along with new parts and the shims I successfully tore apart the gun, cleaned and lubricated it (got rid of the gritty action), and got it back in fine working order
Thank you for having your product available to novice DIY folk like me.
