I have an old 686 no-dash, meaning that it is one of those in the recall, and no, it has not had the recall mod done to it, and I haven't had any problems with it. Best I remember, S&W stamps an "A" inside of the yolk where the model number/serial number is when the recall mod is done. IIRC, there is a little pin on the hammer that connects the firing pin that is not in spec with some, but not all 581,586,681 and 686 no-dash and -1 revolvers. Some are in spec, some not. IIRC, what would happen would be that if they were shot with hot magnum loads, they would be more prone to primer back-out causing the cylinder to lock up. Chances are, if you have one of these and have actually been shooting it with mag loads and have not had any problems, you won't have any problems because you didn't have an out-of-spec pin in the first place.
