OK. I "think" I found my answer. From what I read here:
http://www.sec.state.ma.us/cis/ciswel/weltomas.htm
It sounds like when I spoke with the licensing officer way back when, he may have viewed me as a "new resident", because I was living out-of-state for 9 years even though MA was still my home of record while I was on active duty.
Under
Gun Laws (M.G.L. ch. 140, s. 131 and ch. 269 s. 10, 12B & 14), there is this paragraph:
No where does it say I need to do a FA-10. Only that I had 60 days to get what was (at that time) a FID first and then a LTC later if I were to carry the gun outside of my home. I suspect this is because any guns that I had already owned were not a recent purchase in the state while I was an actual resident.
Would anyone disagree with this assumption? Man, this state has got more gun laws and regulations than guns itself.
