I carry the 9MM to shoot you in the leg..........Sorry better you then me!
Some sort of OO and slug combo.....The odds of a person hitting a bear while hiking and being chased by a jeep with teeth is slim to none. By the time you pull the gun out and realize the amount of shit that is running down your leg it is a little late to try and hit it with slugs or 44 or what ever your carring.
So do Like I do and shoot your buddy in the leg and run like HELL.......My wheeler is faster then your anyway.
