You are overthinking it. You are not going to be attacked by a Bear and if you are attacked by a Mt Lion, you will not see it coming. In the extremely unlikely event that you ever need to draw your glock, you will be using it point blank and the bullet you use will not matter much.
Opt for the lighter bullets, cuz your Glock will just be dead-weight while hunting....
