Home Defense is more of a software problem than a hardware problem, as are most issues regarding self defense.
So far no one has mentioned much at all in the way of software, as is so often the case. Please let me remedy that. For starters, take a look at
http://www.nrahq.org/education/training/basictraining.asp . There you'll find links to the NRA's basic firearms classes and a link to the search tool which allows you to locate an instructor/class near you.
One of the classes offered is the Personal Protection In The Home Course.
According to the posted description, the class "teaches the basic knowledge, skills, and attitude essential to the safe and efficient use of a handgun for protection of self and family, and to provide information on the law-abiding individual’s right to self-defense. This is an eight-hour course. Students should expect to shoot approximately 100 rounds of ammunition. Students will learn basic defensive shooting skills, strategies for home safety and responding to a violent confrontation, firearms and the law, how to choose a handgun for self-defense, and continued opportunities for skill development. Students will receive the NRA Guide to the Basics of Personal Protection In The Home handbook, NRA Gun Safety Rules brochure, the Winchester/NRA Marksmanship Qualification booklet, course completion certificate, and Lesson Plan (print 10-06).
The NRA Basic Personal Protection In The Home Course participants must be law abiding, adults (at least 21 years old), and experienced shooters (shooters able to show mastery of the basic skills of safe gun handling, shooting a group, zeroing the firearm, and cleaning the firearm) to maximize what can be learned from this course. Proof of shooting experience can be one of the following: NRA Basic Pistol Course Certificate, NRA FIRST Steps Course Certificate, NRA pistol competitive shooting qualification card, military DD 214 with pistol qualification, or passing the Pre-Course Assessment."
Software. Yeah, it's more fun to yammer on about hardware. But in the event you have unexpected and uninvited callers, the software you load into the computer between your ears is a lot more likely to save your bacon than whatever hardware you pick out at your favorite gun shoppe.
