Well, am I the idiot or what. The guy told me 18 and never checked the numbers, although I did open the crane (nearly blind close up). Can't get one past you, CG. It is a model 17-7 with 6" barrel TT. TH. full underlug barrel with ribbed top and partridge front site that is pinned. He also saw me come home and walked over with a piece of paper from the S&W performance center where he had them do a trigger job on it. This thing has a "wish trigger" on it. Point gun down range without touching trigger. Place finger very lightly on trigger. When the target gets into the crotch of the figure "eight", wish it to go off and it does. This thing has to be under three pounds. I do not have a scale, but I would put it at 2.5 pounds max! What a fine piece of S&W workmanship! Finally got lucky!
