....I don't "fidget" or have adult A D D but I do like to carry in the small of the back and so when I do, a more positive safety is something that makes me feel a bit more secure (knowing where my gun is pointed when holstered).
Also, after a lengthy conversation with my wife in choosing her ccw, I just couldn't argue the point she made that "what's the harm having a frame safety and just not using it if you don't want to". In her case she uses them always. If a safety wasn't on her rig, she would not carry a round in the chamber. In my opinion, I'd rather she flip the safety rather than rack the slide.
