I'm definitely not a Korth apologist. Never owned one, never will. But I did read Gun Test's write up on it in their July 2002 issue and they called it their ultimate conditional buy. They said it was as close as any production gun has ever come to answering the question "What kind of gun could you produce if money was no object". That's actually not a direct quote but that's the idea.
Some of the details: each gun takes 4 months to build, the steel is proprietary and rates 60 on the Rockwell scale, they rated the machining as good as they had ever seen, multiple sub 1 inch groups at 25 yards. I found it interesting that they said that the polishing and bluing was superb and that the dirt "seemed to leave the gun on it's own accord" and it stayed cleaner than any gun they had ever seen. There was obviously much more but you get the picture.
I'll end by saying that I think that kind of money for anything, revolver or semi-auto is crazy. But, for those for whom money is of no concern, I guess there would be no reason not to own something that has the extras to offer, no matter how little real world difference it would make.
