What i usually carry is my springfield xd 45 acp with 2 extra mags in a backpack. I mainly carry it just in case something happens and i do get lost i can fire shots off to alert people to my location. I also carry bear mace, a couple good knives, survival kit, and something to purify water. I carry the 45 acp just in case in a rare situation something does happen and i do use it even though i probably could only get a couple rounds off if something charges me it should do the trick. The trick if you do get lost is to have a good survival kit and most important know how to use it. I know this may be off topic but at minimum make sure you have a whistle, 3 different ways to start a fire) i usually carry 2 lighters, a bunch of strike anywhere matches, magnesium fire starter, little coleman fire starter sticks, compass usually 2, 100 feet of para cord, a couple splace blankets, fish hooks and line, 2 big black trash bags, gps(learn to navigate w/out it and use it as a last resort dont soleyon them I've had to look for lost people and when found them they said their gps broke and they had no clue where to go), flashlight, enough food to last me a couple days( nothing fancy like a few cans of tuna), extra batteries for everything i have, TP and baby wipes probably most important unless you want swamp ass, and a couple of glow sticks. I use a medium size ziplock and i can fit everything in it. Hiking in the back country as far as animal attacks isnt as near as dangerous as city folk think. Most problems are man made. If i remember correctly from my survival class a person can live 2 hours w/out shelter 2 days w/out water, and 2 weeks without food ( granted conditions do apply to this). But anyways back to the main question i carry a 45 acp. If you have any questions pm me.
