I think something to store a handgun in with the intent of keeping your gun out of the hands of children and thieves should be constructed of something better than 18ga steel. I think a thief with a standard size screwdriver could bend it up and pop in open. I know a standard claw hammer will tear it up in a hurry. Your kids won't do that, but how hard is it to get into without damaging it? Most of the electronic ones seem pretty easy to compromise. Again, young children probably won't be able to.
