I recently acquired an early model 6 shot 648 from a friend's estate and have yet to shoot it. He wasn't a revolver guy and the gun had come to him from his father's estate just a few years ago. I don't know any history on it but it appears to be little used and came with the box, cleaning kit, paperwork, etc, and it seems that the factory Combats were on it from new. Any and all feedback is appreciated. I hope to get it out in the next week or so.
