Alright guys and gals, here is the story. my FFL has found a source of Smith Model 67's that look brand new and almost like they have never been fired and for a fantastic price. As some of you know Linda had her 67 blow up on her many years ago and I'm looking to replace it for her. Now here is where I need a little help. The 67's have been modified by a police department to be DAO only revolvers and I want to know what I would have to do to return it back to a SA/DA revolver. I don't believe there was much smithing involved but again I'm not real familiar with wheel guns as I am with autos so I'm open to suggestions.
