This thread has turned into the "Do YOU transport loaded mags" thread of 2019!
IANAL. That being said...remember that Lawyers are paid to keep you out of jail, NOT tell you what the law says. There's a HUGE difference. Staying out of jail, in the extreme sense, means we each tuck our tail between our legs and walk around with a guilty look on our collective kissers. Downtrodden, BEAT, on the DEFENSE at all times. Transporting according to FOPA Rules while still inside NJ. Do most of you know the difference? Can you type it w/o looking it up? I Doubt it. Doing it lawfully and doing it "Candy-Ass style" are completely different. Lawyers always give advice on the extreme side of surrendering your 2A rights. That way no one can point fingers and say "He told me xyz about transportation" under cross examination. They always take the safe play. And you lose rights that way!
I choose to push the envelope. A "secure package" is brown craft paper & bakery string. On your front seat. Orrrrrrrrrrrrrrr locked in the trunk of an automobile, completely naked, no case, holster or box or other impediment of access of any type or kind, and then merely tossed into the trunk to get scratched by the other 199 naked, UNLOADED firearms contained therein My 12th grade edumacation taught my punctuation and its' MEANING.
If the next wiz-bang lawyer tells you to remove your firing pins or field strip prior to transporting, are you Richard Craniums going to comply & say "YES SIR, MORE PLEASE!" Just askin' for a friend...
