Welcome to the forum and gun ownership in Massachusetts. it seems to routinely take 8-12 weeks under normal circumstances. I’m not familiar with Marblehead specifically though.
The licensing officer probably stopped responding to your emails because he feels that you are annoying him. If you piss him off he could drag his feet. Is it right? Hell no. But in this state you will get to exercise you 2A rights when they say so. Unlike most states you can’t even buy a bullet, much less a firearm without the states permission slip.
It sucks. It isn't right. It’s a violation of our rights and it won’t change until gun owners band together and elect a state government that sees it the same way we do. Of course we could win a Supreme Court case if they deign to here one of the gun cases currently before it.
Thats why it is so important to support GOAL, COMM 2A, GOA, and other organizations that share our values.
