Every one of your points are valid.
However, please consider this:
1. I don't have children in the house, nor do we have visitors with children. A locked steel gun cabinet is just as good as a safe to keep kids from gaining access to guns.
2. All my firearms are covered by my home owner's insurance with a rider, and I have the NRA coverage.
3. Were the "results you saw" in your own home or in some safe maker's advertisement?
4. I leave my house all the time; only a safe cracker would target you, since you have a safe!
5. My steel storage cabinets are bolted to the floor and to the studs in the walls. The locks are pick and drill resistant. There is no way thieves could rip those cabinets out without expending a lot of energy and time.
6. The guns I have concealed in my home are not where a thief would expect to find them.
7. Most home burglaries are targeted to hit the premises when the owners are gone, and then last only a few minutes where they choose easy pickings.
8. A deliberate attack on a safe full of firearms presupposes that the burglars know the victim, know his whereabouts, and have the time to crack the safe and make off with the guns.
I am all for keeping your guns "locked up."
A steel gun cabinet does that just nicely.
My safe is so heavy that it has its own gravitational field. Firearms from surrounding stores keep getting caught in its gravitational pull and swallowed like a black hole...
1. Your homeowners insurance will probably not cover any of your firearm loss, in theft or fire.
