Smith and Wesson model 627 snub nose 8 shot. in my opinion the best handgun to carry for back packing/hiking in the lower 48 states. If you add Grizzly ammunition to it, its a good Montana and Alaska handgun too for Brown (Grizzly) bear and Moose defense.
Magnum LeverGun & Revolver - A wonderful combination for a backwoodsman. Handgun for close defensive work against vermin, and a carbine to boost ballistics for hunting and defense against larger animals.
