I owned the 617-1 with 4" bore and a 6 shoot cylinder (is this concept correct?)
617-1 -
Congratulations on a fine revolver. You were right the first time. You have a 6-shot 617-1 with a 4" barrel.
According to the
Standard Catalog of Smith & Wesson (aka Supica & Nahas), the 617-1 variants were made from 1993 to 1996. If you supply the supply the serial # in the form BDY3XXX (i.e. don't include the last few numbers for security reasons), someone will look it up the the Std Catalog and let you know.
They must be double action only or I would have seen these guns a cowboy shoot competition?
ReadyRob -
Double action revolvers are generally able to be shot in both double and single action. Some will have a gunsmith render them "double action only" (DAO) by removing the hammer spur and the DA sear on the trigger. Some revolvers come this way from the factory (e.g., model 642). If it's a double action revolver and has a full hammer, though, it's DA/SA.
Those who shoot in Cowboy Shoot competitions are trying to be a bit authentic, and AFAIK, the competition itself requires the use of a SA revolver, such a Colt SAA or clone.
What does underlug barrel mean? Did a search and couldn't find out much. It looks like maybe the ejector rod?
The underlug is the large section of the lower barrel the encloses the ejector rod and runs the length of the barrel. Look at some images of the 617s predecessors, the Model 17 and the K-22, and you'll see the difference. Functionally, I suppose it might make the barrel a tad stiffer, and the heavier muzzle weight helps tame muzzle flip during recoil (more of an issue with it's big brother, the 686 .357 magnum), but it also makes the 6" version feel muzzle heavy to some.
What are we talking about $ wise, just ball park but I gotta get one (or two) of these beauties.
They're great guns, but you'll pay for it. Locally, I'm seeing new 617s for $700-$750. If you look around you can find used ones a bit cheaper, maybe $500-$600. If you're going used, and like blued guns without the underlug, keep your eyes open for a nice Model 17 or K-22. You can probably find a good one for the price of a used 617. It'll be a great shooter as well, and will hold it's value.
