Some more of the OPEN IN CASE OF EMERGENCY - Carrying in MA on a NR LTC-A(ALP) Kit
1. A wallet card with firearms lawyers practicing in your home state (NH for me) and MA
2. Copies of MA NR-LTC(ALP) for when they sieze your original, say they didn't, and say they can't find a record you ever had one. For your lawyer above.
3. A list of firearms with SNs and photos for when they can't find your siezed firearm or say you can't have it back as it's not MA-compliant. Likley it will be melted for manhole covers before you can get it back...
4. No reason to surrender your home-state permit to a MA LEO, so don't volunteer to hand it over.
