Keep in mind, that if you have a house gun, and use it to protect your house or its inhabitants, the local constabulary will take it away from you until the case is closed. It may have funny engravings or other things done to it. In other words, get a gun you won't feel bad losing if you have to shoot a bad guy with it. A nice Sigma in .40S&W or a good used 45 series Smith might serve your needs.
