I'll have to agree with sniper762. The Taurus Judge is capable of shooting .45 Colt (not my first choice at snakes), .45 Colt shotshells, or .410 shotgun shells.
Easy to carry, easy to store be it in your pack or your car. Suffices as a tolerable self-defense weapon, too, as long as you keep your shots in close.
