I sleep with a .357 revolver under the pillow. It started when I first left home some decades ago & learned that parts of the world are not really nice places. Never had an AD. Like Silverlance, I can fall asleep & wake up with a straight finger outside the guard. If I hadn't developed this habit, I'd be dead. For me, it would be imprudent to be without a ready means of effective defense at a time of extreme vulnerability.
