Rich has an article about storing guns in a house with kids.
I use a big safe and then a small quick access pistol safe. The pistol safe is a DAC Sport Safe, which is an electronic safe with a mounting plate at a great price. The DAC Sport Safes fell victim to Herblock’s Law – “if it’s good, they’ll stop making it.”

Is the DAC immune to easy opening like these?
Not that I can tell. It has thick steel and locks up tight.
