I think you're not entirely wrong though, I think there is some other citation in MGL that actually talks about the AFR.
Not that it matters, though, I mean what is the punishment for the state if they don't obey the law? It's not like someone gets arrested for not doing it the right way.

The large cap roster has been modified probably less than 5 times since 1998. Boston Glob (spelling intentional) is one of the "newspapers of record" and charges EOPS full boat (IIRC it was ~$8K) to publish the roster of EOPS Approved Handguns. So it would be beyond stupid to publish the totally irrelevant large cap roster more often than when it was revised, regardless of the law.
As for the EOPS Approved Handgun roster, that does get updated usually quarterly and IIRC the law calls for publication quarterly.
In any event, it is ONLY useful to MA Dealers in telling them what handguns they MIGHT be able to legally transfer. Since the AG releases NO LIST (yes the AG's CMR claims that they must but they never have and never will), even for dealers the EOPS List is of very questionable value.
