No vent rib? Hell that's one of the defining features of a Python. I sure won't look right and the Colt purists will have a fit.
While they may be able to produce an excellent revolver, I doubt they will be near the quality of the original. Mass produced on CNC machines will never equal hand fitting by a skilled craftsman.
And that price! Really? I'll pass.
I think that just like the Cobra, Colt is trying to cash in on a name and history with a lesser product. Probably going to be a good gun, but it won't be a Python.
BTW: the last real Pythons, which were only produced by the Custom Shop, weren't very good. A friend of mine bought one. Three trips back to Colt and it still wasn't right. He got pissed and sold it at a loss just to be rid of it.
