Have had a 39-2 for years. Love it. Fits my hand like no other.
Couple of quirks about Smiths, in my experience. One, they like to be clean, real clean. Two, they like to be kept lubed. Nothing special, plain old gun oil works just fine. But don't try to shoot a Smith dry. It just won't work.
Also remember that at various times Smith has had QC problems. The early 59's were probably the worst. At the time they came out they were the only game in town and everybody and their brother had to have one. I can remember early - mid 70"s Shotgun News prices of over $350, wholesale. To meet demand, Smith cranked them out as fast as they could. And at times quality slipped. Also be weary of the late 80's gun of the week craze. For a while there I think Smith simply pulled parts of the the bin blindfolded to create a new variation. Let's see the full size stainless slide on a blued compact frame, DAO, with novak sights would equal the S & W 5650, no, it would be a 6927, no that's not it. I don't know how many variations they came up with back then, must be in the dozens.
