An article on the common 9mm (9x19), Parabellum, Luger, etc. (all are the same cartridge), is in the works. So far, eleven cases, six against black bears, five against brown bears, all were successful.
A Mak or .22lr in hand is better than a .44 Magnum home in the safe. That being said I have black bear around my place and I carry a .357 magnum or .44 magnum with hunting loads.
