The value of an M1 Carbine

Talking with a buddy of mine (who is easily as armed and ready as me). He brought up his father in a more volatile area only had an M1 carbine (no ammo but that's a separate issue); and it got me thinking. Obviously, a gun in the hand is better then nothing at all but I think the old Carbine is a very fitting weapon in a home defense situation. I think this little amount of turmoil has really got people looking to their own ability for defense and maybe fewer people should be looking at optimal weapons and should be concentrating on what they have and getting ready with that
