Anyone ever do this? I have a S&W 642 that is pocket carried daily (waist band holsters are in transit) and when I go mountain biking I placed the revolver in my backpack. I don't like the idea of it being off my body, and secondly, it is going to be HORRIBLY slow should I need it. But I wear basketball shorts over spandex and an under armor shirt. Doesn't exactly leave a lot of room for concealment. Any thoughts on this topic?
