AMAZING....Could this be an obsession?? 
Maybe for some of us it's an obsession (I include myself as one of the obsessed), unfortunately for all of us these days regular thoughts safety and personal defense have become necessary.
Porthole: great post! May I be so bold as to 'tack on' a few gems from one of my instructors, Clint Smith - owner and top-dog of Thunder Ranch in Oregon:
"Make (your attacker) advance through a wall of bullets. I may get killed with my own gun, but he's gonna have to beat me to death with it, 'cause it's going to be empty."
"The handgun would not be my choice of weapon if I knew I was going to a fight....I'd choose a rifle, a shotgun, an RPG or an atomic Bomb instead."
"The two most important rules in a gunfight are: Always cheat and Always win."
"Don't forget, incoming fire has the right of way."
"If you're not shootin', you should be loadin'. If you're not loadin, you should be movin', if you're not movin', someone's gonna Cut your head off and put it on a stick."
"When you reload in low light encounters, don't put your flashlight in your back pocket... If you light yourself up, you'll look like an angel or the tooth fairy...and you're gonna be one of 'em pretty soon."
"Do something. It may be wrong, but do something."
"Nothing adds a little class to a sniper course like a babe in a Ghilliesuit."
"Shoot what's available, as long as it's available, until something else becomes available."
"If you carry a gun, people will call you paranoid. That's ridiculous. If I have a gun, what in the hell do I have to be paranoid for."
"Don't shoot fast, shoot good."
"You can say 'stop' or 'alto' or use any other word you think will work but I've found that a large bore muzzle pointed at someone's head is pretty much the universal language."
"You cannot save the planet. You may be able to save yourself and your family."
