I've owned quite a few Pythons and L frame Smith's over the years, all are great guns. Yes, one of my Pythons did start to go out of time. It is a 2 1/2" Nickel gun which was carried as a duty gun from its birth in 1965, and had been primarily used with factory 357 ammo, usually around 2,000 to 4, 000 rounds per year between practice and qualifying. When it began to go out of time, in late 2010, I sent it in to Colt's Custom Shop, where they retimef t, replaced some worn parts, installed new sights (red ramp front/white outline rear) at my request, and sent it back to me "good as new." Fragile? Nah, 45 years of constant use before needing minor maintenance doesn't indicate that to me. I also have a blue 4" I bought new sometime in the late 70s which has seen a lot of use and is still tight and like new. In 2011 I bought a stainless 6" Python to replace a stolen older 6" and sent it to Colt Custom Shop for their factory tune, specifying tune for 357 magnum. All those Pythons are super smooth both in single and double action, and the fa Tory tuned gun is incredible. I recently sold a 586 no dash in nickel which had an extremely smooth action (almost as good as the Python, but the 586 had been professionally tuned) and a 586-3, which was like new and had a decent action, typical Smith, but none of my many Smith's quite approach any of my Pythons in terms of action smoothness. I don't like selling guns, but it is some times necessary. My Pythons are never leaving, no matter what. YMMV, everybody has their own preferences. I can't speak to the new Pythons with any real experience, but I like their DA, and I understand the SA can be remedied by some judicious stoning. When they first were announced, I ordered one, b I t didn't really see the need to effectively duplicate one of my old Pythons. If Colt comes out with an 8" version, I will probably add a new one. Best wishes and good luck on your decision.ooo
