TECH TIP: Cylinder Shims
TECH TIP: ENDSHAKE
Barrel-Cylinder Gap and EndshakeThe 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" but some sources say as much as .010" or .012" is acceptable.
Next, hold the cylinder forward and re-check the gap, write it down.
There may be no clearance here at all, the cylinder may touch.
The difference between the two numbers is the amount of movement or Endshake your cylinder has, it should be between .002" and .004" on most Ruger Double Action Revolvers, other manufacturers clearances may vary.
Our Cylinder Shims can be used to adjust your B-C Gap and Endshake.
Cylinder Shims will move the Cylinder Back, or Rearward, ending
Barrel to Cylinder Contact and/or Rubbing, and give better Hammer Strikes.
Excessive Endshake is a more harmful than a slightly wide barrel gap
Crane or Yoke Shims will move the Cylinder Forward, to compensate for wear
at the Yoke/Crane - Frame area.

Hi Lance,
I am a retired LEO and was the Firearms Instructor and Armorer for my dept.
Today I rebuilt my S&W 63 with your 6 Pak Cylinder Shim Kit that I received yesterday. It was great to remove the end shake without having to stretch the cylinder arbor. It is now like when it was new!
I had used this revolver for training my officers in revolver snub nose usage and have lost count how many rounds had been put thru it.... Your quick response and excellent product is deeply appreciated. I am now one of your biggest FANS ! Keep up the good work and I recommend your business to anyone in need of your products !

If you need a shim for a model not listed:
First, I would contact the manufacturer to ask if they supply cylinder shims,
some companies do, although they usually are somewhat expensive.
If not, if it is a Double Action, you would need to determine where to place the Shim.
Some are like the Taurus or Dan Wesson and install below the Front Cylinder Bushing,
so you would measure the ID and OD of the Front Cylinder Bushing.
Some are like a Single Action Revolver and can be installed at the Front of the Cylinder,
to bear between the Cylinder and the Yoke Frame
Others are like the S&W and are installed at the Rear End of the Yoke Shaft, in the bottom of the Cylinder, effectively lengthening the Yoke Shaft.
In any case, if you can supply me with an accurate measurement of the shaft, cylinder ID,
yoke shaft ID/OD and a picture of what you are doing, I may be able to help you
find a shim from or current inventory or possibly make tooling to fit your request.
You can send questions to: Lance@TriggerShims.com

Hi Lance,
Your shims worked like a charm! I had a couple of S&W's with really tight B/C gaps - an early 28 that I just picked up with B/C gap between 0.002 and 0.004 (due to a slightly non-concentric cylinder face), and a 686 that I’ve had for a while that had some custom work done with a gap of just under 0.004. A bit of end-shake was enough to cause a bit of B/C interference on both. The 0.002 did the job on the 28, and the 0.003 solved the 686. I couldn’t be happier. You have a fantastic product at an amazing price. I will spread the word. Thanks and God Bless,
