WOW thats a loaded question.....I will try to help you out there.
- You will want your guns locked in the trunk in cases and if possible your ammo in the back seat on the floor in a box.
- Maryland dose not veiw your permit to carry as legit.
Good luck I will try to find you actual law tommorow but these should help you in the right direction.
I will be traveling from the free state of Va to MD to teach a firearm class. Can someone advise me of the rules/laws regarding carrying and/or transporting handguns in your fine state?
