The only two brand spanking new S&W revolvers I have bought was my first, a 28-2 six inch in 1977, and a 586 four inch, when they were first introduced, as a duty gun. Sold that original 28-2, but still have my 586.
Quite a few used models of various flavors, some like NIB.
My most recent, as far as age, is a 629-6 four inch, MIM & lock. It also has one of the smoothest DA pulls of any Smith I own, and is one of the most accurate N frames I have, regardless of barrel length or dash number.
My most recent is a 28-2, "S"-prefix, four inch, I picked up at a gun show a couple weeks ago. Set up a target at 25 yards in the backyard, in a snow storm. Shot 24 rounds, standing on my hind legs, single action. 6 38+p 125 Rems, 6 357 125 Rems, 6 Fed 158, and 6 357 Win Silver Tips, 140 grain, I think. All hit about an inch high, using a dead on hold, and grouped in a fist sized clutter. Yea, its a keeper.
