So, I am going on a long backpacking/camping trip. I am hoping to cover about 35 miles through rugged terrain, so every ounce matters. I was considering bringing my .380 for protection which weighs only 14 oz with a full magazine. My other option would be my 9mm which weighs 30 oz with a full magazine. (more weight than I like) Mind you, I used to take a buck knife as my only protection. I understand that the .380 will not stop a bear or other large animal, but neither will my 9mm. My hope is that a couple of warning shots into the ground will scare a bear off. (likely to only encounter black bears if at all) Because if it comes charging I know the 9mm, .380 and the Buck knife aren't going to stop it. I would also have the gun for protection against any undesirables or crazies (scarier than any animals) that I may encounter. Thoughts?
