I agree with what you are saying. I can't say down the road whether or not I will have more NFA stuff. In MA, I'm honestly not so sure but if I got to NH, yes I most likely will. A lot of it comes down to money than anything else. There is also nothing that says I can't do a trust down the road and submit that too. Hell, I could do a trust tomorrow and assign another lower if I wanted and get a stamp faster.
One thing, in my opinion, which is a positive from getting them to sign it, is the fact the signed it. I will say that the initial call to the chief to inquire about it was not made by me. They had really never done one before and at first really had no idea what I was looking to do. Once I got to talk to a few of the guys at the station, everyone was really cool about it. There was a little miscommunication at first but it wasn't pertaining to what I was trying to do, just meeting times got delayed due to storms. Which, I can't place blame for that. Maybe in the future they will be more open to signing the forms? Who knows? It was also kind of nice to meet some of the people down there. In my city you don't meet with the licensing officer when you do your LTC paperwork. I had a different dept. process the prints since I was able to get in there over the weekend and those guys were really cool. One of the guys who did my prints has an SBR and 2 16" AR's. He was a super nice guy. So all in all, at least in my case, I think I can take some positives out of it. For most people who can't get that initial "in" with the department I would recommend the trust and if I get into doing more NFA stuff down the road I am going to do a trust.
