Having owned a slew of Smith & Wesson revolvers in the 1970s, I am very fond of their line of guns. A Model 12 was one of my first purchases after turning 21 in 1970. Foolishly it was either sold or traded away, which was the fate of all those wonderful revolvers. Their was a local hang-out (gas station) where many of us (cops included) swapped stories and guns in equal portions. I really miss those good old times!
The pictured revolver showed up recently at a local gun shop, and I snatched it up before anyone else noticed it. While it has some noticeable surface wear, mechanically it's perfect. No one had messed with the side plate screws.
In the 70s, you could get Bianchi and Safariland leather made specifically for whatever revolver you owned. The pictured Galco holster is made to fit guns with 2 or 3 inch barrels. Thus, the overhang of leather at the bottom of the holster.
Accurate and light to carry, my Model 12 sees some concealed use, but not as much as my newer 637.
While I don't get carried away with searching for "grail" guns, I always check the new and used revolver sections of gun stores for some of these old "classics".
