OK, I gotta step in here. If you think a S&W revolver has had every part "hand fitted" because it comes from the Performance Center, you're going to be sorely disappointed. The fitting on the Performance Center revolvers I have seen over the past few years has been absolutely abysmal--worse, in fact, that the fitting on the stock revolvers from the production line with the MIM internals. I think all the little old men who sat on three-legged stools and knew how to hand fit regular forged parts on S&W revolvers must have retired.
That could be true now, and not to defend because I've had this same conversation with Jim Rae. I own three older PC revolvers, a 3-inch and a 4-inch 686 Carry Comp and a 646. All are very nice wheelies. Are they better than a factory floor production gun with an action job? Probably, yes. I also have a PC tuned 686 which could give all of them a run for the money. I don't know about the current PC wheels but the old ones are great. The Target Champion is an older revolver that was modified with Nills when they got it. It is only available overseas. Just my .02.
