Clint Smith is well trained, and a very smart individual when it comes to fighting with guns, however I believe one's choice in home defense weapons may also hinge on what their particular state laws entail, the area in which they live, and wether or not they have other family members living within the home. Personal choice also plays a big factor here, some preffer one type of firearm over another based on the fact that they are much more proficent with one type over the others, and therefore more comfortable using that particular type of firearm.
With that said....I live in The People's Republic of gun hating, Liberal New Jersey. There is no shooting at anything outside the home unless you are 1,000 feet from any road, it's daylight, you're hold a shotgun, and you have a hunting license on your back. If someone is climbing through your window with a gun in their hand, you better wait until they are far enough inside so when you do shoot them, they don't fall back out of the house, or you just might find yourself rotting in a state pen....
You can't shoot them with a hollow point, or you'll be charged with using excessive force, and if it can be proven that you knew the invader, they will attempt to turn it into a domestic violence case, and charge you with man slaughter.
New Jersey is such a wonderful place thanks to our politicians, the likes of Jon Corzine, and Frank Lautengurg...... :banghead:
So for me, it's a 9mm XD loaded with Federal 147gr. expanding full metal jacket, an alarm system, and a german sheppard.........
