The reason to send any revolver or semi-auto to get more work on it is just the same as why you have a Precision Center at Magnum Research and the Performance Center at Smith and Wesson. Heck Ruger even has a custom shop. Because you seek to refine the basic working package you have and personalize it to your aesthetic and/or functional whims. And this is why gunsmith and barrel-porting professionals have job security. Because these admiral works of design deserve refinement and care. It is not about money. It is amount the goal. At least that is what I make of my experience.
