I'd like to make sure I am protected for a hiking/camping trip out West. I am not scheduled for it but my next gun will be for this purpose. I currently have a 12 Ga 870 Magnum, a Kahr PM 9 9mm and a G23 40. Is the 870 enough? And if so- what ammo? Slugs? And if the 870 is leaning against a tree, and I have to resort to what is hanging on my side, what would I want to stop a charging creature at close range? (Like a bear?) I'm pretty sure if all I have is the 9mm or the 40 I should file the sights smooth so when the bear sticks it up my rear it doesn't hurt as much. So I think the 9 and 40 are not even worth taking. How about a conversion barrel for the 40 to make it 357 SIG. I think still not near enough, right?
