A lot more S&W's out there in nickel than there are Colt Pythons. Factory nickel plated Pythons command a huge premium. If it comes with box and documents and is in excellent condition, that would be an average price these days.
You can bet if I was selling one like it, with the box, papers and such, I'd be asking that for it. I might not get it, but that's where I'd start. I could always come down, but I couldn't go up.
I've been out of Colt collecting for quite a while now, but this post had me again looking into my sold guns binder (records and pics) and found this 6" blue, Python, 1971, no box, no docs.
Still amazed that these guns bring so much and even Covid, inflation, old shooters passing, seems not to have dulled this very particular market segment.
I bought it so long ago that my records show the OTD price was $529, sold about 8-1/2 years ago for $2,450 locally to a commercial airlines pilot. I remember when doing the F-F deal I jokingly asked if he was going to carry it daily into the cockpit. He said yep...as soon as I can get a leather craftsman to make a nice holster and attach it to his Jepp case!
Picture that rig going through the TSA checkpoints, or average Joe watching him traverse the terminal!
Vintage Pythons are nice guns but there are way overpriced and prices don't seem to be coming down any. I've had three or four in the past at different times but never could get used to the double action stacking pull so they went down the road for something else. Wish I had a couple of them now that I gave $500 or less for so I could triple or quadruple my money to the right collector. Single action was fine with them. I'll stick with my L Frames.
