Hello, I have seen several go in the 600-650 range on gunbroker and gunsamerica the last few weeks ( they were used ). I paid $800 for mine new.....so if it is in reallly good shape, I think it is fair. I would still try to get them down a little though.
I just bought same gun in black finish for $620. I packaged it with a Dan Wesson my bro inlaw was buying.
It has a Kimber magwell installed and a Wilson Combat mag in the chamber. Fresh, bright sights, as well.
