Elmer Keith sure had good things to say about them in Sixguns. I owned a 439 (an upgraded 39 with better feeding and firing pin safety, the second handgun I owned) and I won't argue with Elmer. You might ask the same Q over at the Smith and Wesson forum to see what the specialized fans have to say. They made a few changes to the 39 during its production: depending on exactly what you picked up - you might have a super-collectable gun. More likely, though, you just have a great shooter. Do ask over at the S&W forum, though, to make sure you're not sitting on a treasure!
