Frankly, with a rugrat in the house, I'd get a gun safe.
Wouldn't a home security system be better? I mean, think about it, what if you had walked in on the robber AND he had already found the gun? *shudder*
And the reality is, for the vast majority of people, unless you're well schooled in the use of firearms, pulling the trigger on another human being, even if you are frightened for your home and property, isn't something easily done.
I'd love to see statistics on how many people actually own guns for self protection, have been in the position where they had to use them, and actually DID use them.
