I got my Firearms ID Card recently and I am looking to buy a Remington 870. I want to wait and save up for a nice safe. In the meantime, my uncle has a very nice Winchester safe and has offered to let me store my gun there if it's legal. After I buy my gun, can I keep it in my uncle's safe? I have read all the laws, but they are ambiguous. I know NJ is super strict with firearms, so I want to make sure everything is perfectly legal. Does anybody have experience with this or know what the rule is?
