I know this is strategies tactics and training geared towards self defense.
But for woodswalking where self-defense may be more against four-legged or slithery foes, my revolvers will accommodate a wide variety of rounds, from shotshell to lead in roundnose, wadcutter, and semi-wadcutter and in metal jacket from FMJ to softnose or hollowpoint, in power levels from .38 Spl, .38 Spl +P, to .357 magnum.
Being armed makes me alert to avoiding bad situations.
