Had our retired S&W armorer fix and smooth the action. Said that this was one of the strangest jobs he ever did. Action was full of crud but there was no wear on the internals and no endshake which he believes caused the gun to do what it did. Took it to the range about ten days ago. Two cylinders fired at fifteen feet double action. Slick as snot on a doorknob.
I now fully understand why the 3” K Smiths are so desirable...
