Silly question. Presupposes I could get lost in the woods. Maps. Compass. Planning. Oh, plane crash? Outlier. Supposes I were to a.) get on a plane despite my aversion to Thugs Standing Around, b.) disregards the hassle would I have to put up with to even be ABLE to transport a firearm past Thugs Standing Around and c.) I’d still have a compass in stupidly TSA-limited EDC bag *heh*) and general knowledge of the area downed in.
Still, noodling around in the woods, if only one firearm carried, it’d probably be a Ruger 10/22 Takedown (model 11100, because 18.5” barrel as opposed to the 16.x” barrel. There’s room in the pack). If allowed 2, then selecting a handgun would be variable. Depends on area. Alaska? Yeh, not going there, and not only because I don’t want a .44 magnum as a backup. *ouch* Don’t own one anyway. VERY different to piney woods in America’s Third World County™ where a handgun that can handle “snakeshot” might be the choice (depending, in part, on area and season).
Still, “lost in the woods”? Who does that? Oh, yeh. Dunning-Krugerands. The same folks as would ask such a silly question. Got it.
