Before being shipped overseas in WWII, my Dad patrolled the coast highway with a partner from CA to Canada. Up near the Canadian border, his partner was squatting, taking a dump, when a bear poked its head through the brush at him. The guy emptied his 1911 into the bear's head at about 10 feet from the squatting position with expected results. And the encounter helped clear his bowels at the same time. I don't recall if it was a griz or a black bear and Dad is now deceased.
