Nothing wrong with a Python but a 686 is probably 85-90% the gun a Python is for half the money.
Watched a 2 1/2 blue never fired Python sell at auction for $5500 about three years ago.
It was from a private collection that had about 25 Pythons and that one brought more than any of them.
I had the chance to fondle a Korth 357 once and I was probably the most well made piece of machinery Ive seen. If I was gonna drop thousands on a revolver I think thats the way Id go
It priced out at $3500 about 15 years ago.
