My personal favourite defense gun has always been the Beretta Jetfire in 22 short http://www.lukehimself.net/wp-content/uploads/2012/05/beretta190.jpg I have carried it for many years including while hiking. I never leave home without it in my pocket.

I remember this one time while hiking with my girlfriend in northern Alberta when out of nowhere came this huge brown bear charging at us, and boy was she mad. We must have been near one of her cubs.

Anyway, if I had not had my little Beretta Jetfire I
would not be here writing this today.
Just one shot to my girlfriend’s knee cap was all it took, and the bear got her and I was able to escape by just walking away at a brisk pace.

It’s one of the best pistols in my collection.
