I assume you are looking to buy one that you have found. They are great guns, basically the last of the .357s with checkered topstrap and barrel. It handles magnums like a k frame handles .38 specials. It is a heavy gun and probably not the best for backpacking, but a great range gun.
There were just over 5000 made. I have seen them priced in the $1300-1500 range. They are getting priced at the top of my affordability for a shooter type of gun, but the prices have more than doubled since I bought mine.
I really like the N frame full lug guns, have several and shoot a lot of rounds out of mine. If you like it, get it, you won't be disappointed.
