*whispers* Because you can.

That's the answer for 90% of what we put in our kits anyway. *laughs* And you are right, there is no "perfect survival gun"- all guns are "survival" guns from the right perspective. If I had to pick the closest to ideal, it would be either a .357 or .44 with a 6" barrel, a similiarly chambered carbine, or a combo gun in 12ga/.30-30 or .30-06 with some sub-caliber adapters for a small game round.

For me, the why has a lot to do with feral dogs- not dumped pets, but true ferals, second or third generation. They are wild animals, but they are close enough to domesticated ones that they don't fear humans. Attacks have been rare, but I'd rather not be on the wrong end of one- almost once was close enough. Rabies has also been an issue around here, and while a rabid feral isn't something I've heard of, there is just the factor of mercy. If I was some place with catamounts, boar or aggressive bear populations (or bigfeet) I would carry something on the large side. Down south, I might carry something loaded with snake shot, so that if I do get bit I can hand the doc the dead snake so he can give me the right stuff. (And so I can eat it later- I hold a grudge, and as Man-the-Toolmaker, I win.)

In a longer term situation, hunting can be a part of it.

For bugging out, the main reason I'm bringing my Garand with me is becuase it is a family heirloom. I'm not leaving it behind if I have to evac, just like some people can't leave behind wedding pictures.
