Hey folks, trying to get opinions for a lever action gun to carry around in the forests of Northern California when out and about. I'm looking for a caliber that would be effective against black bear, mountain lion and coyotes if a problem arises. I will not be putting a scope on it, just open sights. Anyone have a hand gun cartridge they use in a lever rifle and is it deadly enough for the above situations? Let me know the make and caliber.

Thanks.
