Hey guys can anyone tell me the going rate on 617s these days? I stumbled upon a NIB 4" 10 shot 617 for $730 at a gun shop and also a used 4" 10 shot 617 a used one for $580. The NIB seems a bit high from looking on internet sites, but was wondering about the used one. The used one locked up tight, looked brand-new and was a 617-6. Also can anyone tell me if that's the latest model? Sorry if this has been gone over, been awhile since I've visited the forum.
