For home defense the last situation you want to be in is someone already in the house or even worse standing over you or being awakened by gunshots fired. You may want to think about improving your home with additional security systems. Many people would think that a home security system would do the trick. That certainly would help but by the time you hear an alarm go off it would probably be too late because someone is already in the home. Image yourself waking up from a deep sleep, getting clothes on possibly, accessing a firearm, and collecting your stuff. You typcially have anywhere from 1-3 seconds to be ready for a bad situation. I am not sure about you but it takes me a lot longer to get ready in the morning for work. Think about ways to gain the element of surprise. I have a 4 point IR detection system around the home starting with the driveway 500' away. As each zone is violated I get distingushing beeps so basically I know by sounds where any individual is around my home. This definitely gives me an advantage. Couple this with video survellance and interior protection and you will have a sound place to stay at night. It may seem like a little overkill but this is 80% of the challenge. Also never use your firearm at night without an accompaning light. You need to know who you are engaging if necessary. I prefer one mounted on the firearm but you can use an external light with proper techniques. Spend some time securing your home so you and your family can sleep better at night. It's a one in a thousand chance but worth the investment.
