Today, H.R. 358 – To amend chapter 44 of title 18, United States Code, to more comprehensively address the interstate transportation of firearms or ammunition was introduced to congress.
This amendment is to address the problems that people have when flying or driving through states such as New York and New Jersey and legally transporting firearms. These states have and will detain and arrest people just because the firearm is not legal to possess in that state, even when you are just passing through the state and not staying in it.
The law currently says;
18 USC § 926A. Interstate Transportation of Firearms
Notwithstanding any other provision of any law or any rule or regulation of a State or any political subdivision thereof, any person who is not otherwise prohibited by this chapter from transporting, shipping, or receiving a firearm shall be entitled to transport a firearm for any lawful purpose from any place where he may lawfully possess and carry such firearm to any other place where he may lawfully possess and carry such firearm if, during such transportation the firearm is unloaded, and neither the firearm nor any ammunition being transported is readily accessible or is directly accessible from the passenger compartment of such transporting vehicle: Provided, That in the case of a vehicle without a compartment separate from the driver’s compartment the firearm or ammunition shall be contained in a locked container other than the glove compartment or console.
