Best Gun For Personal Defense Against Bears... My personal favorite bear defense gun has always been a Beretta in 22 short! Over all the years I've been hiking in bear country, I never leave without it in my pocket. Of course we all know the first rule when hiking in the wilderness is to use the "Buddy System". For those of you who may be unfamiliar with this, it means you NEVER hike alone, you bring a friend or companion, even an in-law, that way if something happens there is someone to go get help. One time I was hiking with my brother-in-law in northern Ontario . Out of nowhere came this huge brown bear and man was she MAD! We must have been near one of her cubs. Anyway, if I had not had my little Beretta I'd sure not be here today. That's right, one shot to my brother-in-law's knee cap and I was able to escape by just walking at a brisk pace. That's one of the best pistols in my gun safe!
