I own 3, not counting air guns. If money wasn't an issue I would own as many as i could fit in my house, heck i would buy a storage building just to keep my guns in Every one of my neighbors own guns. Even the old lady across the street, she was outside one day just unloading on a snake in her back yard with a 22 pistol. I heard at least 30rounds go off. I think everyone needs to own at least 2. That away if one fails when you are defending yourself you have a back up.
