Barrel-Cylinder Gap and Endshake
The gap between the back of the barrel and the front of the cylinder is known as the Barrel-Cylinder (B-C) gap. The Front-To-Back Movement of the Cylinder is the Endshake.
In order to properly measure these clearances you will need a Feeler Gauge Set. K-D Tools USA Made # 161 Deluxe Feeler Gauge is available all over the internet and at most good auto parts stores for under $10
To check B-C gap, hold the cylinder rearward and insert the (thickest that will fit) feeler between the Barrel and the Cylinder, this is your Barrel-Cylinder Gap, write it down, it should be between .004" and .008"
Next, hold the cylinder forward and re-check the gap, write it down.
The difference between the two numbers is the amount of movement or Endshake your cylinder has, it should be between .001" and .004"
Our Cylinder Shims can be used to adjust your B-C Gap and Endshake.

SP101 Cylinder Shims

Dear Lance,
 I ordered a 4 pack of Trigger and Hammer Shims along with Wolff Reduced Power Springs for my Ruger SP-101, chambered in the Federal .327 magnum. I love Ruger products, but as you know some Ruger Revolvers somehow escape "Quality Control". Such was mine. A heavy hammer spring along with a not so sweet trigger action, made this gun uncomfortable to shoot.
So a combination of Wolff Reduced Power Springs along with your Shim Kit has made this into what will become one of my favorite revolvers. But what I really want to Thank You for is the You Tube Video that made the Disassembly and Assembly go a lot easier . Thank You Again. You have a life long customer.  Jim B in WI

How to Install the RDA Shim Kit
and Reduced Power Spring Kit in a
Ruger SP101, GP100 and Super Redhawk
Double Action Revolver.

In this video, I install a TriggerShims RDA Pak of Shims,
and a Wolff 17113 Reduced Power Shooters Pak in a Ruger SP101.
The Trigger Pull before was very tough in Double Action, with a inconsistent Single Action trigger pull weight of 5 pounds.
After this install, the Double Action trigger pull was Much Better, and the Single Action Trigger Pull Dropped to a Very Smooth Consistent 3 1/2 Pounds!
And the best part is there were no permanent alterations to this gun.

Do you have a 2011 or newer SP101 in .22LR? Read This:
Hello Lance,
I took apart my new Ruger SP101 .22 LR today and wanted to report my results!
I used a hone sparingly and used Mother's Mag & Aluminum polish and smoothed all mateing surfaces.
I reassembled using your shims, the 8# trigger spring and it fires consistantly with different types and brands of ammo using the 10# hammer spring!!!!! I am thrilled. I also tried the 9# pound spring, it fired consistantly single
action but misfired a few times using the double action.
So...In my case anyhow, I was able to use a 10# hammer spring in my .22!!!
Thanks Again Lance!
Joe in AZ

There are Several Ways to Accomplish Removing and Reinstalling the Hammer Spring, but I wanted to Show the Simplest 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.
