I found the wording somewhat ambiguous.
I currently have a fire proof safe, and aside from the reservations of a poster above (regarding fireproofing being damaged by desiccants), is there any legal reason I wouldn't be able to store pistols (no trigger lock) + ammunition?
Consumer fire safes are pretty easy to open - http://www.youtube.com/watch?v=BRTnJVwYkJs&feature=related
"(ii) stored in a vault, safe or room that has been specifically constructed or modified for the secure storage of restricted firearms and that is kept securely locked; and"
Could this not be interpreted to mean that the safe/vault must also be designed/modified for the secure storage of firearms?
