Hi, I am going hunting this fall for deer, and I am bringing a Glock 19 as backup against the possibility of a black bear attack. Now, I clearly know that a 9mm is not the best caliber, but right now it is all I have. What is the best ammo to use? CorBon 115gn HP with 460 ftlbs of energy, or FMJs NATO with I think about 370 FtLbs of energy. Thanks!
