Big medicine for dangerous critters.
The one that comes to mind is of course the ultra light weight Smith & Wesson model 329 44 Magnum revolver that they claim that that they made with you in mind.
While firing full house 44 Magnum rounds in a 24 oz Revolver may seem like the dream of one of those guys that like to hurt, It would be just the thing if you happened to get between a she bear and her cubs. That phony Naturalist and his girlfriend that ended up on THE INSIDE of a bear a couple years ago in Alaska should have had one. Of course they were too stupid to even consider one.
it gives you the absolute maximum power to weight ratio Safety wise a double action revolver is about as good as it gets.
