Item # C-D-H/T

D Frame Diamondback .22 Revolver
May Fit Other D Frames including ~

Trigger (.126" X .207")
Hammer ( 126" X .221")
Diamondback Revolvers built from 1966 to 1991
in Calibers .22 LR and .38 Special
These shims are made to fit revolvers with
nominal 1/8" Hammer and Trigger pins
Pistolsmith Tony contacted me about a new in the box, 1980 or 81 Colt Diamondback .22 Revolver. He noticed that the hammer and trigger had quit a bit of side to side play. In single action mode, it was no problem, but in double action the looseness of the two parts in the frame and on their respective pins allows them to shift position enough that the hammer would cock off to the left and impact the edge of the hammer channel in the frame
Fail To Fire ~ FTF
Tony said he was getting a lot of FTF in Doule Action, so he contacted me and asked if I could help. Tony disassembled the revolver and took pictures and accurate measurements, drew diagrams and prints, and from those I produced these shims for Tony's revolver.
While the shims did not fully cure the FTF problem, (he believes a new mainspring will be the final cure for that) they did remedy the Hammer Rub issue and helped immensely.

Lance ~ the shims are perfect and restored a 111 year old Colt Police Positive Revolver to shooting condition. There was excessive cylinder end shake and this caused the hand to force the cylinder forward to the point it would hit the barrel with no clearance. Two .003 shims put it perfect and now all is properly aligned. Thanks Again, you saved me a ton of money getting this old gun back in shape ~ JP

Republic.... I like the sound of the word. It means people can live free, talk free, go or come, buy or sell, be drunk or sober, however they choose. Some words give you a feeling. Republic is one of those words that makes me tight in the throat - the same tightness a man gets when his baby takes his first step or his first baby shaves and makes his first sound as a man. Some words can give you a feeling that makes your heart warm. Republic is one of those words. - John Wayne in the Alamo
