I came across and purchased a 4" 686 no-dash (serial #AABxxxx) for next to nothing. The catch is, the gun is complete, except for the internals (hammer, trigger, springs, etc.). This revolver has had the recall work performed, as it has the "M" stamp. My question is, do I order 686 no-dash parts or will some of the parts have to be from a later model, to fit with the recall work?
