Even though I feel all Colt Pythons are overpriced, that is on the lower side for a 98% blue 4inch. I don't think you could go wrong at that price; that is if you have the money and know you are paying a high price for a gun, that in my opinion, is a little over hyped. Yes they are very nice guns, and they are probably the most beautiful DA revolver around. Though I have not shot one, I have heard they don't come any better. But I still feel paying over a $1000 for any handgun I plan to shoot is too much. But then again I am not exactly made of money and looks are not the most important thing on my list.
That being said, if I had the money I would jump on it. That is about $300 cheaper for one of lower condition around here. You could sell if for hundreds more easily if you feel you made a mistake.
