I used to carry a 9mm with a 15 round clip when I went backpacking. I wasn't worried about other hikers, I was more concerned about the Bears and Mountain Lions. After a couple of years hiking with the gun, I decided just to leave it at home. Never ran into any Mountain Lions and I only seen a few beers and wild pigs running the other direction. Would I bring one on a Overland Trip? Most likely no.
