This is why I carry a small semi-auto pistol when I backpack/camp in US National Forests which allow open carry.

Our threats down here are Mountain Lion, Coyote, and Black Bear. I feel that the sound of a ground discharge would discourage a Mountain Lion and Black Bear but a dead coyote won't come back to create mischief.

My nephew that goes with me didn't want the extra weight but I feel it is worth it and 1 is sufficient to deter or put an end to an animal attack.
