So it would be legal to carry around a non-functioning gun? What about a gun that jammed on the first round, that means it didn't function. (All rhetorical). Would that be OK? As I have never looked into this specifically, but I assume what you're saying makes no sense. Maybe Flapp can chime in as he post more credible info.
Carrying around a non-functioning replica, for example, would still be a crime.
