"It's to protect our greatest assets honey, our family"
We live in NYC so getting the handgun permit was a challenge in itself. It took me a while to convince my wife that it was the right thing to do though. I grew up in FL and have gone clay shooting with my father since I was 12 and owned two shotguns. But getting my wife on the same page when it came to handguns was another story. I think one thing that definitely made it easier was Occupy Wall Street. At one point they were threatening to do some bad stuff.
Look, you can turn on CBS, NBC, etc. or simply open a newspaper and find some awful story about someone or a family who wasn't able to protect themselves. Even thought there's such a small chance of that ever happening to us, it's always better to be prepared.
We have two young boys (6 and 4). I keep my two SIGs locked in their boxes with trigger locks too. It would probably take me about a full minute to access them if I really needed to, but at least I know they're safe from little fingers.
Good luck!
