RE: auto for home safety
I agree with most here. Keep them full. The myth of having to rotate magazines and empty them is just that. A myth. I have my Kimber .45 either on my person, or on the nightstand beside the bed.
But if there is an intruder in my trailer, I'll reach for the 12 gauge pump that sits in the corner next to the bed. I don't want to shoot down the length of the trailer with a bullet or slug due to my daughters being in their bedrooms at the other end of it. 3" magnum shells loaded with #4 shot should be a great deterrant to anybody, if the sound of the sliding working doesn't cause them to mess their pants.
