I think you are underestimating the cost. New Pythons and Diamondbacks could easily be in the $2k to $4k range and even then, they may not be equivalent to the originals.The market for a revolver such as the colt Python is most likely very small. Especially at what it would cost to manufacture something as precision and polished as a Python. In today's dollars it would have to retail for $1500 - $2000 dollars. In a world where everyone wants 15 round plastic guns the python would be a niche market player at best.
