Ok, I know I caused this problem and swear I won't do it again. I've had a couple of stuck case situations (IPSC) and slapped the cylinder pretty hard. Now (when hit hard) sometimes the cylinder slides back a little overcoming the little bump on ther frame designed to keep it on the crane. This is a stainless steel Smith. Does anyone have a recommended gunsmith who can build the hump back and return the gun in a reasonable length of time? Thanks
