Greetings. I have a first year production K-22 Outdoorsman, I'm in the process of disassembling for a thorough cleaning. What is the best method to unscrew and remove the ejector rod? The knurled end of the rod on this early model does not fit through the hole in the yoke so need to remove it. It's beyond hand tight and I don't want to mar the rod or bend anything. Am I correct that the threads are reversed on a 1931 production revolver? Is there a way to remove the rod without any special tool?
