Yes, I know there are many threads on this. (http://glocktalk.com/forums/showthread.php?t=941981&highlight=massachusetts for example) I have read most of them and still am not satisfied I know 100% the legal method to carry through MA from and to a place that I have a permit for. Yes, I have read the federal law that supposedly overrules MA law about transporting firearms through the state. I still have yet to see a case that was actually prosecuted and won/lost. I guess I need to see some sort of proof that this holds for MA other than "...well shoot, just don't get pulled over and if you do don't consent to search..." I have also tried the pack n go trip planner on carryconcealed.net which is very nice actually and quotes the federal law i see everyone else post: "TITLE 18 PART I CHAPTER 44 § 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 drivers compartment the firearm or ammunition shall be contained in a locked container other than the glove compartment or console." I read this as saying that no state can make carrying a handgun through it completely illegal if the above protocol are followed. True? Also, I found this that contradicts the "lock it in your trunk and don't stop" answer that is usually tossed out: "Non-residents may obtain temporary licenses to carry through the Firearms Record Bureau in order to possess and transport firearms through the Commonwealth. All non-residents must comply with all Massachusetts laws regarding transportation and storage while in the Commonwealth." http://www.sec.state.ma.us/cis/ciswel/WELTOMAS.HTM Also, I may contact MA state police and ask them for their interpretation on what is written on their state page and what the federal law states. I am not entirely sure if that is a bad idea or not. So, help me beat a dead horse so that I can sleep soundly as I will be driving through MA a lot for as long as I inhabit this earth.
