correction: glocks made the AG mad because MA AGs are moonbat statist elitist communists....the AG couldnt describe an LCI if you gave them 6 weeks and a chalkboard. they use the "LCI" crap as a red herring to draw attention away from their agenda of disarmament and towards a manufacturer (ie Glock). if Glock made the gun 100% perfect it still would be disliked by nanny state. we should stop giving credit to asswipe beaurocrats.
In 2005? There was a 3 or 4 month period of time when Glock tried to sell guns in MA and they put a shit trigger in them. That went away of course. Occasionally you'll still find these guns in the wild (I call them "window" glocks) but most of them got returned to FS.
Theres also some small, lame-o dealer in MA (forget what/who it is) that purports to sell "compliant" glocks that installs shit triggers in them before sale.
There are ZERO guns that are approved for CMR940. The AG does not approve guns for CMR940. Ever. The current divination of AG reg compliance is "We're selling the guns and waiting for the AG to sue us... or not".
