I saw an advertisement a couple of weeks ago in a gun mag., and my initial thought was, "those are the goofiest grips I've ever seen"! But curiosity got the best of me, and I read about and thought about the design. Showed them to the wife, for her 638 S&W, she thought that they might be worth a chance. Well, we ordered them, put them on, and she (confession - me too)like them! For all their strange appearance, they seem to function real good!!! memtb
