Re: over engineered
Gun safes are fine for sporting or hunting guns, but have an obvious disadvantage to those who purchase a fun for self defence. If someone is breaking into your house, you need your gun right at that moment - you don't have time to fiddle around in a cupboard, enter a combination, get the gun out, get the bullets out and load the gun.
It's an inherent conflict between having the gun ready for self-defence and having the gun safe from accidents involving children/drunken-idiots. You can't have both.
