I have a new ejector rod that I ordered from S&W to replace my chewed up ejector rod. When I install the new ejector rod and close the cylinder, it darn near impossible to open the cylinder again. I can push in the button to swing the cylinder out, but the cylinder doesn't want to swing out. If I put the old ejector rod in, the cylinder swings out like normal. What am I missing? Could it need some fitting as in filing off some of the end of the rod? Here are pics of my new and used ejector rods:
