I would trust any of my Sigs to Sig. Generally, all Sig internals are stainless steel coated with Nitron. I've polished interanl components as well as external parts with no negative effects whatsoever. While I don't think I'm "anal", I do take care of my guns, so I understand your concern. While I have never sent a gun back to Sig for service, I wouldn't hesitate to do so. Once a bit sketchy, their customer service has improved greatly in the last couple of years. I think that has more to do with the "Americanization" of the company. Anyone who has dealt with European CS with know what I mean. I must confess that I can't imagine having a gun and not shooting it though. I own a 2nd gen Colt SAA that I love shooting, yet I've had people gasp in amazement when I do. They are tools and need to be used. That's just me though. If I could afford a Ferrari, I'd drive the piss out of it(not abuse), and laugh uncontrollably all the time.
