The Speed Six is my favorite revolver. I currently own 5 Speeds and 1 Security. I have never sen one shot out of time. That"s not something I can say for the S&W 66. I bought a Speed Six Postal Inspector gun when they were put on the market. Mine was very used and had some end shake but it was still in time. I think your hand will wear out before the gun will. The only down side is the action will never be as smooth as a K frame.
