I have a .45 colt semi and 12 g shotgun. And a permit. And a security system, and cameras, and a black belt in mouth karate.(ha ha) The question awlays is, if it com down to it, can you protect youself without hesitation, hell yeah or I'd die trying. Growimg up overseas in some rough cities was kinda interesting.
I don't leave the porch without a shotgun due to rattlesnakes, here, the law of the land is to be armed not really people but wild animals, snakes are really bad here. I don't know what all the flap is about shooting a .12, it doesn't even kick me and I'm small.
I used to have a robot dog who actually stopped a burglary in progress in California. It barked at the intruders, it's infared sensor went nut, his head startd spinning, damn funny!!!!
