Well, I cut my teeth on a new 586-nd back when in LE and shooting PPC. Accurate, smooth, and never an issue thru many thousands of rounds.
Also have a new model Python and Anaconda. They sure are pretty. Fit and finish is impressive. The DA on either feels light and smooth, better than newer S&W's I have shot. About as smooth and light feeling as my well worn in 586, but different, if that makes sense? Certainly not bad as one poster implied.
SA trigger pull is another story, and neither new Colt is as light or crisp as a decent S&W trigger. Not bad, but not what they could be. I have read on line that this is because of a lockwork design that actually puts pressure against the cocked hammer that slightly lifts it before release. Both my new Colts do it, and it is supposedly to help pass CA's drop test.
To me, a much bigger issue is reliability. The gun forums are full of folks who have been having failure to fires in their Pythons, and to a lesser extent, Anacondas, mostly DA, and sometimes SA. Way to many to be just a couple disgruntled customers. Blame has been placed on primers not being seated properly, hard primers, reloads, foreign ammo, ect. Probably partially true, but the problem is this same less than perfect ammo seems to function just fine in other brands of guns.
I personally have not had any issues with either of mine, but the Python only has about 100 rounds thru it so far. My subjective opinion is Colt, in search of a light and smooth trigger, may have gone too light on the hammer spring. There has already been one update to the Python V spring recently due to light hammer strikes. I might add that after after almost 3 years of production, Colt offers zero replacement or aftermarket parts. They don't even so much as sell a replacement front sight for their replaceable front sight models. They refer you to the aftermarket.
I want to be able to pick the new Python, but until reliability issues are addressed, I can't. To me, the early S&W L frames are still the top pick in a .357 revolver.
