Holy moly, the amount of pontification on this thread is amazing. Because I love this subject, I tried hard to get through it but I think most of you missed the most important post of the 24 pages. The article Cfrey referenced is an analysis of
actual bear encounters when handguns were
actually used in self-defense. Successful defense=attackee lived. Caliber, energy, rounds carried, sectional density, blah, blah, blah. When it was all said and done, even the .22lr was effective in thwarting most bear attacks. Really good, informative article. Makes all of the theories and arguments pale. Carry on!
Using a pistol to defend against bear attacks seems to be a viable option.
