I've been using the GunVault for several years and have thought of it as a balance between accessibility and security (since I often have young grandkids at the house). I keep it bolted onto a fixed shelf in my dresser. I have always assumed that it is relatively secure, never having tried to actually force it open. I have, unfortunately, a troubled teenager in the house that I would never allow unfettered gun access and have assumed that he also could not easily force open this gun safe. Has anyone out there ever tested the security of the GunVault, i.e., tried to force it open with a heavy screwdriver, claw hammer or pry bar? Reading a thread on another gun related website I was impressed with the Ft. Knox safe, especially in the way the lid overlaps the container and thus is more resident to attempts to force it open. Any thoughts on this?
