I have been looking at general fun guns and I have narrowed it down to the Hi-Point 995 carbine, or an HR1871 single-shot rifle (probably in .308). The only thing keeping me looking to the 9mm carbine is it has the potential to be used as a reasonably-effective defensive weapon for someone else (should I need to let a friend use it or whatever). However, I don't know if I'm putting too much stock in that characteristic. Other than my personal 9mm handgun, all I'd have would be a .22 pistol and .22 rifle, neither of which are all that great for defensive uses, obviously. But, like I said, I don't know if I'm putting too much stock into potential for defensive uses. The .308 would be my first rifle-caliber firearm and I have always wanted one, but obviously the 9mm carbine would make a better "friend" gun should that need ever arise. What do you think about my concern? Do you guys pay much mind to the potential need for someone else to use one of your guns in some emergency? I would probably be more excited about the .308, and am leaning in that direction. I just want to make sure I don't leave myself "undergunned" for when the zombies take over .
