Interesting stuff I've been thinking of getting my SGC too, hubby shoots a lot but is convinced he can't get one. Would this preclude me from having one as a partner? (His guns are cabineted by a SGC holder with his own but its a PIA when it needs cleaning/ work)
You should never grant access to your cabinet to any non certificate holder. So you would have to retain the keys and he would not be allowed access to the guns. That should be sufficient.
