Well then Ed, you are the perveyor of poor craftsmanship and are defending something you should not support. If you knew something of metal heat treating, you would not support the processes used to color your guns. A number of people here have a collective knowledge from the gun manufacturing and gunsmithing business that is pretty impressive. Others here have technical expertise in metal processing that give them the foundation to give you the critical information you've gotten. You have "Ed Landers", expert in your eyes and not many others.
