I have over 500 rounds through my LCR (38 model), mostly 38 special with a few +P. I love the little gun and I wasn't expecting a swiss watch; but it has always been a little loose. I don't think I have stretched the frame, or peened the crane much with the shooting I have done, but it has an .008+ (depending where you measure) BC gap, and .0055 endshake. I have never seen any information or utube videos on how to remove the ejector extension to get the cylinder off the crane so endshake washers can be added. In addition, I have not seen endshake washers specifically for the LCR and I don't know if they cross reference to any other revolver. Any suggestions?
