If the safe does not open when the bad guys arrive, the gun ownership expense is a waste, and the safe is another waste of money.
Simple but readily accessible concealment can be a better solution. It relies on training of the people in the household.
My first demonstration of firearms always includes at least three pieces of fruit with increasing caliber, ball to hollow points.
On the last round, I remind them again that human brains are largly water just like the watermelon I am holding. The last hit is with a 12 gauge and number 4 shot; when the watermelon explodes, their eyes reveal the impression I want to make. Then we go shoot .22’s at pop cans and have good time. If the nubie points wrong, verbal corrections are simple, and they respect the danger implied.
If you cannot trust everyone in your household with the respect of the guns, you should really consider a heavy and concealed safe. Last weekend, sadly, a 13 yr old in my town stole a pistol from another kid’s house, was playing with it with his friend at another house, and now the friend is dead.
The pistol was only stolen because a kid in the household brought in the thief and showed him the gun, so the thief knew where to find it. In other words, the gun owner could not trust everyone in his household.
A safe of this type might be an in between solution, but training everyone with respect for firearms is really even more important. My kids know to not even discuss guns with their friends, and should one of those kids be in my house, their is no way a firearm is accessible or even visible. (They have also been instructed how to answer Obamacare questions at the doctor’s office, without lying.)
A 13 year old with a fatal gun shot to the head makes for one really ugly funeral. This safe might make a danger go away for a little bit, but please consider the simple ramifications and responsibilities of gun ownership, with or without the safe.
You must have the trust and respect of your kids. Frankly, this safe could become a theft attractant if their bad friends even know about it being in the house. The bad friends will know when you are on vacation, and they will already know to bring a crowbar.
