I always have a loaded LCP II in my pocket. Sitting on the porch, doing yard work....
I keep a loaded M&P 9mm in my nightstand. (No children or grandchildren)
Since I have a police officer living across the street, I'm confident he'll take care of any miscreants that wander into the dead-end street, when he's home. If away on duty, well, that's the criminals unlucky day. If they're smart, as in wise up looking down the barrel, they'll wind up with three hots and a cot, and a new suit.
