I know it's not an answer to your question... but...if you're not going to display them, you might as well secure them. They have a way of multiplying, and it's nice to be able to leave the house and know your investment is secure. Safe really is the only way to go.

The most peace of mind I get from my safe is being able to return to my house knowing that one of MY guns isn't going to be aimed at me when I walk in...
