Well, that's one thing that bothers me. I can see maybe a rifle that you have in the house that isn't necessarily for SD, but a SD pistol has to be loaded. It would hurt if you threw it at the perp, but I don't think it would do the job that most would like.
I dunno. If your SD pistol is as reliable as Thorsen's 1911, you'd be in better shape if you'd planned on throwing it.
