I've seen several New Frontiers in local gun shops. They either don't get snatched up as fast as the SAA's, or they are making more of them. I bet they are making more of them, even though there is less demand for them.
Colt is funny that way, and it kind of pisses me off. They have consistently held Peacemaker production to just under market demand for as long as I can remember. They are doing their best to keep the damn things just scarce enough to maintain some false aura of "specialness" and/or "mystique" about them.
Granted, they have always been better in fit and finish than the average handgun, even when folks were complaining about them. Now that they are back on their game again, they are truly exceptional. And yes, there is a good deal more machining and subsequent hand fitting required of its antiquated design - it's by no means "designed for manufacture" to anywhere near the degree of, say, a Ruger Blackhawk with all of its investment cast parts.
There is all of that, but most of us are convinced that Colt artificially keeps production below what it could be. Word on the street is that they are going to reduce Peacemaker production next year, now that they are getting it right again. Gotta keep 'em "exclusive" for the collectors, I guess.
Oh well, maybe that just means they are planning on firing up the Python line again... one can only hope...
