Oh boy. A friend of mine emailed me this : Keep in mind this guy was a protective service agent in the military, drove/rode in the hard car for generals and US presidents when visiting other countries, and has shot more cool weapons and blown up more shit than I will ever get to. He's got a picture from when he was in the military shooting a HK briefcase MP5 Anyway. I haven't started to argue with him yet about his home defense choices, I just replied with : "I'd like to hear your reasoning for choosing those weapons and calibers for home defense, as well as your reasoning for not keeping a round in the chamber of a gun in a safe." Anything you guys would like to add?
