They are not the easiest to find, but there's a few around. I think your specific application and personal preferences will limit your choices more than anything else. For example, is this for a CCW, or home defense, or both or plinking, or posing for pictures, etc.? Also do you prefer stainless, do you mind things like alloy frames, hideous front sights, or internal big brother locks? Weight is a definite limiting factor if you are thinking of a carry piece. I like that there is so much interest in the .44 special. Only recently came to appreciate the caliber myself. I like the suggestion of the 441 sans lock. Also S & W makes the best revolvers around (wow, there's news), so if you can find a used one in great shape, or unfired, that would be the sure thing, IMO. The older, original Charter Arms Bulldogs have a pretty good following. You can find one in good shape here and there on the web. The Charco and Charter 2000 models get mixed reviews. I guess we should know if price is a drving force in this equation as well.
