That's horrible. But I think that what I propose would comport with your desires.I sold my magnum to my brother who then moved to Texas.
Caught by surprise at his door, he was held at knife point and cuffed to the toilet.
The thiefs took all they could including my old gun.
A lock box is fine if bolted to the floor.
The gun would have been more useful had my brother been more careful at the door.
Now there's a loose weapon registered in my name!
See where this is going?
My brother did.
He now has permit to carry a 9mm.....and does.
To carry is convenient & secure. Being careful when answering the door is good too.
