Python will never be mass produced enough to make it just a good carry gun. The last time I saw a Python in a holster was a local cop in Baraboo WI and that was circa 1979.
I also don't think a new Python is really a good investment regarding a collector's POV, Colt's new 1903 is an example, in fact, the original 1903's in collectors grade don't really go for that much especially compared to say a collector's Colt Peacemaker.
If Colt is asking $1500.00 for the Python then it's going to be a limited sale targeting people who have an emotional or nostalgic connection and nothing more. I can get a beautifully restored Model A for under $15,000 when they once commanded a higher price and certainly the original investment was much higher but what would I do with it?
Revolvers may one day make a comeback when magazine pistols will all be regulated to 8-10 shots but by then, I think guns will just be outlawed entirely and this will happen within the next 30 years if we don't have that fight out now when my generation, the generation that were connected to the greatest generation, are still alive.
The Python was a very nicely tuned gun out of the box, visually pleasing too, but structurally it is a K frame without the forcing cone issue. It was a "practice with .38 load .357" revolver just like the K.
Is it worth $1500.00? Not as an investment.
