So I have a class A license to conceal and carry a firearm which was issued to me by the city I live in which is Methuen. When I took my handgun course the instructor told us that carrying a firearm or even transporting one through the city of Boston was illegal. I tried to find something to back this up on the internet but can't seem to find anything. SO, can anyone tell me, Is it legal to conceal carry a firearm in Boston if you are licensed to do so? thanks.
