Just a few more points. A good heavy safe doesn't need bolting down. Mine was so heavy, we had to take the door off just to move the datgum thing. Once it got filled, the incredible hulk couldn't budge it.
So here are my recommendations:
1) Get a heavy combination safe.
2) Don't get an electronic safe. An electronic safe can be fried by an electro-magnetic pulse, and EMP attacks are an ever-increasing threat.
3) Get a security safe, not a fire safe. Fire safes are not security safes and vice versa.
4) To protect your valuables from fire, put the safe in a basement. The worst that should happen is that the house partially collapses on the safe. In most cases, your guns should be fine because of the protection basements afford. Fire tends to burn upward.
5) For maximum security, get a combination safe with a key. The key locks the tumblers, making it even more difficult for an intrusion.
6) Get a home security system. Use ADT or Brinks. It will add extra safety, plus save you $$$ on your home insurance.
7) Send me a copy of your key, your combination, security codes and the location of your safe as a backup in case you lose your key or forget the combination. Oh, and include your address and the times you're going to be on vacation so we'll be extra-vigilant.
That's it. Can't think of any more security measures. Oh, and I like to secrete a few weapons between my door and the safe just in case. Cold Steel makes a number of
Nightshade knives, made of durable and cheap fiberglass they call Grivory. They go for about ten bucks per, so they're cheap enough to have one almost anywhere.
