I bought one a couple of days ago. Beautiful gun. Best trigger I've ever used. Locks up tight as a tick. I'm not crazy about the grips, but I've seen much worse. They'll probably stay if for no other reason than I like my guns to look "stock out of the box."
I've seen the Hickok45 video. The fact that his malfunctioned didn't bother me too much. It happens. I'd be disapointed of course, but if it breaks I'll send it back and get it fixed. I haven't fired mine yet, but I have gone through four or five hundred dry fire cycles (with snap caps) with no problems.
I would have preferred the 4.2" barrel, but I said I wouldn't turn my nose up at a 6" one if that's what turned up first. That's what turned up first.
The price was at MSRP, $1499.99. Maybe that's too much for some people, but I've wanted a Python since I had to sell the last one I had when I was out of work for a year or so, some time back now. I figured with prices over $2000-3000 and up I'd never get another one. I might could have waited for the price to drop, but I'm an old man and might not live that long.
I understand the internals are different. Considering one of the grips against the "old" Python was that their lockwork is weak, that might be a good thing. As I said above, the trigger on this one is VERY, VERY good. I handed it to my wife, who frankly wouldn't know a good trigger, from one on a garden hose. Her eyes just got big and she said "WOW! That is NICE." And that's in both single and double action. And no, there is no stacking at all.
