I saw Jeff Cooper's gate on American Shooter once. he had a hallway and on the outter end was the gate and a rod that ran the length of the hall that had to be operated from the other( inner) end. the idea being nobody could open the gate without breaking it wich would wake him up. and he said "if I'm awake I'm OK" talk about waking the sleeping (shooting) giant!
I don't collect guns, I accumulate them.
