MA permit is a pain in the ass, it's $100 a year and only good for a year... and if you don't want it restricted, you have to, well, being annoyingly persuasive. (if you have prior experience, shooting courses, etc... you're going to want to put together a crap flooding package for them- if they get the hint that you're not f***ing around, you'll probably get unrestricted. ) You'll have to get an appointment with CJIS in person to even apply for the thing. At least they allow a remote renewal now, so once you get the damned thing, it's not that hard to keep it, as long as you remember to apply for renewal like 3 or 4 months before expiration.
FWIW even if you get a restricted, it's worth knowing that the card is probably enough to keep you out of jail, but with a bad LEO that might only be a one way ticket. If you're not in MA on a regular basis honestly I wouldn't even bother.
