Well #1 having a handgun is not going to tell you if someone is awaiting you inside your home, or has been in your home. That is what a good alarm system does.

Even if I was armed I would not walk into my home if my alarm had went off. I'd call the cops and let them earn their pay and clear the house.

But other than that, I think Glocks tend to be a bit thick in the grip for most women. I like the quality and simplicity of a good revolver. Especially those holding 7 or 8 rounds of .38 which is very controllable.
