Locks on doors and windows are to keep honest folks out and insurance companies happy. lolI'd rather cuddle my wife in bed than a shotgun. Do you live in a paper house that has no doors or locking windows? If someone is in your rom you are going to have the time or co-ordination to fire it? And yes even with just a primer it will go through drywall. get real.
Pepper shot doesn't get far, you get real. And salt turns into powder when meeting something harder than skin.
We have dogs, the shotgun is beside the bedroom foor, and if any idiot can get past the dogs, I'd already be awake and waiting for him to show his face inside the house. Most times out here in the boonies, once the slide on the shotgun makes noise, people would disappear. It's a very distinctive sound as is the sound of a shotgun round going into the chamber. As far as that goes, we keep an empty round in the chamber, and that makes a distinctive sound when hitting the floor, itself.
