Colt should have jumped when Walking Dead Rick's Python drove up prices.
Still, the 686 is stronger.
Pythons lock at ignition, causing wear faster than the 686 (ie, Pythons will fall out of time faster than the current GP100s/686s).
It will be interesting to see if they beef up what most aren't aware of as a frail system. (frail compared to any other competitors)
I think it's pretty hard to understand someone's instrument of measure when they say the Python has a better trigger than a 686 (current too). I don't think it does.
That said, the vent ribbing on the Python is nice. Even like it on the Taurus 689s.
