I'm still thinking about getting a pistol for general use as well as thinking about it for possible bear protection. I previously asked a question about .40s, but I didn't ask about .45s. The consensus was that the .40 was not adequate for dealing with grizzlys. How about .45s- adequate for big, brown, toothy critters who want to eat me for lunch (talking grizzlies, not squatches)? Thoughts?
