Yea, you're crazy to even think about a 9mm as a viable weapon against a bear. Any anyone who thinks that a 9mm that you are "good" with is better than a .44, .454 etc is crazy also. I might be "better" at defending my self with a sword than a hang gun, but I would rather not fight a bear with one. As mentioned, unless you can put a round in his eye, nose or maybe mouth, all you will do is piss him off. I grew up in northern Maine, we never would think about a 9mm for bear, moose or any large game. Most of the time we carried a rifle and IF we had a sidearm it was usually a .22 for finishing of trapped game or maybe a wounded deer.
