You'd be much better off putting your life in the hands of a 44 Mag with 300-325 grain load in a Ruger single or double action sure fire revolver. $600-$800 is a not a lot of money to spend when your life is on the line. Using a 9mm pistol would be irresponsible in my opinion, but its your hide. Using a pistol a 10mm 210 grain bullet would be a minimum. Years back some guides and backpackers carried the L.A.R Grizzly pistol (now discontinued) in 45 Winchester shooting 230 grain FMJ at 1500 fps. I suppose today a pistol in 50 AE would somewhat suffice. The 9mm is a peashooter.
