$710 worth of performance? I can't imagine that as the SBH is capable of full performance out of the box. Sure, it'll get accurized and slicked up, but probably not $700 worth. That said, aside from the functional improvements, there is something else. Pride of ownership, that perfect look you want, etc. Around 2007, I sent a 5.5" Redhawk to Dave Clements and he performed his magic and also chopped it to 4". That was before Ruger offered that length. It was $500-600 at the time, and I can't do anything with it now that I couldn't do before it went to him. But, I love it and wouldn't change what I did for a second. It's a rare and beautiful revolver. Something to be cherished. It's hard to quantify or place a price on these things.
But for the grace of God, there, I go.
