Of all the goofy things. There are or were professional African hunters who carry revolvers made for anemic, but FMJ revolver rounds for backup against the big cats.
Bell, a professional hunter, has several close encounters of the worst kind with lions. His Webley revolver .38 caliber had said plated rounds. These went through the cat's skull with ease and saved his life. He credited the gun with saving him from being mauled worse than he was. He walked away from all the nasty encounters. Wounded, but not severly.
Hunters who didn't follow his lead in wearing a sidearm have paid the ultimate price.
