"All lawful purposes" is what I put down. It's not a way around it so much, it's what I was told by both my instructors was the proper "legal-speak" to use for "there's no legal reason to deny my right"
"Pistol Permit" and "License to Carry", the same thing, it's interchangeable to me, I just find it physically easier to quickly type "pistol permit"
. Used to just be called an "LTC" for License to Carry but the term doesn't seem used much now
My license reads "Class A Large Capacity License to Carry Firearms" (you want to get the Class A large cap license BTW). However- in MA, there's restrictions from place to place on the whim of the Chief of the local 5-0. For instance, in Boston they won't issue me a license to carry concealed. It's "sport/target- no concealed carry" even though it's Class A high cap, which
used to mean concealed carry. I'm told I need to talk to a lawyer to get that changed to concealed carry- they say I "have no need" to carry concealed becasue I don't have a risky a job for instance- lawyer, cab driver, etc- that makes it "needed" to them. Which is BS, you should see the violent crime map in a 5 mile radius of where I am compared to let's say Dover. The weird part is I know some cops, and they didn't even notice the 'sport/target' restriction. To them Class A is Class A but I won't play that game, it was just amusing that they didn't know that restriction existed. I don't know what the real issue is with the restriction, it's not like somebody from Falmouth with that permit can't carry concealed when they visit Boston...
FID is Firearms Identification card. If you want to buy a pistol, you can forget it if you have only an FID. It's almost the same PITA to get the pistol permit (or LTC) so don't bother with the FID. Ammo, shotguns, rifles pretty much sums that up
The LTC allows purchase of pistols as well as ammo rifles and shotguns- provided of course- just like the FID- those things are legal in MA, and there's a raft of ones that aren't, plus of course it doesn't license you for things like machine guns, although those are possible too. No suppressors in MA but believe it or not, they can be had in other states
You can also get a Curio and Relic license, which is a type of Federal firearms license. I wouldn't worry about that too much at first, but it can allow you to purchase "Curio and Relic" firearms. For instance, my P.38 from 1944 is a "C&R" firearm in MA, I needed a C&R license. There's rules and regulations, etc with that, and the BATFE issues it
MA has done some simply illegal things with FIDs and LTCs but I don't want to go there
