To be fair, I don't think any of those other states had a transaction system like MA does
Haven't most of us already complied through th FA10 and EFA 10 system over the years just following the Massachusetts transaction rules. No one has to regester anything in the new system when it comes into existienst for the state to show a large percent of compliance. Most everything has already been registered. The state well be able to show great compliance numbers.
I suspect people here are not going to want to register, but they might feel sketchy about registering nothing when the state knows damn well what they have already. I would understand someone who complied because of that; they feel they already have registered, and in a way? They have. The state has them by the balls.
What I don't understand are posters saying things like, "I have this old gun from my grandpa that's not EFA-10'd. Where do I register it????" Well, shithead, you don't register it.
