Buy locks...not Glocks.
Always though it kind of a fail situation if you have to resort to gunfire in your home to protect your family.
Yea yea, you posted a knee-jerk glib response without thinking it through all the way... I'll bite.
I hope to never ever fire one of my guns in my house. But, my house is ready if I have to. Consider it the last step in a layered deference.
Also your house is never 100% secure... and even it if has good security (reinforced door frames etc). You wife/children can easily be overwhelmed while bringing home the groceries or coming in from playing outside...
I hope you never experience a catastrophic fail situation where having extra protection in your house could have saved a loved one.
