There is one way to settle this once and for all. Take one gun and re-case color it repeatedly and see if any distortion or brittleness in the receiver results. Three or four times should settle this for everyone. I have several guns which are candidates and would be willing to submit one of them for testing. Any interest in finding out? I accept Dewey Vicknair's opinion and remarks and willing to back it up with a gun. Maybe we can end this rehash of "to color or not to color" once and for all.
