If I did the HK, it would have to have a thread protector to be relatively snag free. I think I want a .45 but not sure which one. This has to be able to fit in the small of my back (and I'm thin) or the inside of the waist of my pants. Something that might work for IDPA would be a bonus I guess. I am fine with a dedicated CCW if it is best. Oh, and I want one NOW!
