I was wondering if anyone had any knowledge on what the safe minimum caliber handgun in grizzly country would be. I am planning a trip to Alaska in late summer and want to have the right gear with me for the trip. I know the fish and game officers carry a S&W .50 cal. I have heard people say a .45 is fine and if so then a .40 is good too because it is actually faster and has the same ftlbs. of energy as a .45. Just curious and want to hear some more opinions on the matter..
