Fair, I am just saying personally I wouldn't be 100% confident that a 45 acp is a reliable boar-buster or bear-buster. One could end up nothing more with an enraged animal and a funeral for their troubles. Shot placement is paramount, mental acuity, and speed are essential which your training and combat experience probably provided. But a 45 acp is better than nothing at all.
First defense - bear spray. Second defense - shotgun or magnum pistol.
