My brother in law (the father of my nephew), suggested that I should take his handgun which he claims is much better than a .357 magnum. He owns a Glock 20 which is a 10mm Auto and I mention this because of the small amount of research I have done about back up Alaska guns and if this particular automatic is acceptable or even should be considered compared to a revolver.
The 10mm will work and so would your 9mm. Phil Shoemaker used a 9mm with 147 grain hardcasts from Buffalo Bore to stop and kill a 900 pound brown bear
