It isn't how many you can get off, it is how many you can hit the target with. As Bill Hickok said, you cannot miss fast enough to make up for poor shooting. Anyone who carries a handgun and does not practice regularly and under stressful conditions is just enjoying false security. A handgun requires practice to be good and if you are going to use it for bear security you should practice on a target moving rapidly toward you as well as other types of stress inducing things such as someone with a stop watch giving you time constraints and practice reloading under stress as well. Just carrying a handgun for bear rotection and not being good with it is about as good as carrying a Louisville slugger, perhaps not even as good.
