If you want to see some nice S&W's check out Chuck's in Buckhead. Jack, the owner, is a swell guy and had some of his personal collection on display a few weeks ago. Serious drool factor involved. He is a longtime SWCA member so you know he has some nice ones.
They always have some nice S&W's and Colts for sale as well, and usually a bunch of fine Winchesters. No better place in Atlanta to shop for Merkel's or really high end double shot guns.
