My wife, who worked for SIG and had weapons training in the Army, has always said that the best weapon to use in home invasion is a shotgun.   You have a better chance of hitting the target, and the sound of shotgun indoors is often enough to scare the crap out of an intruder.     Invasion aren't like TV gun fights!

I will hope/pray for your protection in ways that don't include putting you in position where you have to use your weapon.  *My first wife bought a handgun because her landloard starting making very inappropriate suggestion to her.    We sold that gun after we were married.     She died at the hands of a mass murderer, cancer.

I was wondering if you live alone.    A gun is a good equalizer for women who have reason to fear assault, although there are other protection devices.   I might well buy a gun in that situation.  I would never acquire an automated assault weapon because it can indiscriminately kill by volumn alone, that could include family and neighbors.
