EfewII... welcome to the forum from central Oklahoma. You pose a timely question. As shooting4life said... the 610s are pretty hot right now. I think his estimate for the 610 as you describe it is pretty accurate. I'm looking for one myself... but my pocketbook will only dictate a used one. Good luck!
This gun belongs to a friend that has been collecting guns for years and is just now getting into shooting them. She wants to sell it or trade it for something more to her liking so I'm trying to find out what she should try and get for it. So far I'm getting a lot different quotes. I figured it will be on the high end being an early production gun and of course NIB.
I am going to disagree slightly. If you have the time to hold out for the $1400 to $1500 price tag you might get it, but I think a NIB 5" 610 is more in the $1200 to $1300 range. If I were selling, I would start at $1500, but be prepared to move down in price.
