I'm sorry to hear of your fateful decision to move to Commiechusetts, you WILL regret it.
To your point, you CAN legally bring any gun (not fitting the MA definition of "AW") into MA with you when you move in. The EOPS List of tested handguns ONLY applies to "purveyors of handguns" (MA translation - MA licensed DEALER) and NOT to ownership or private sales between 2 MA residents with LTCs. Ref: MGL C. 140 S. 123
Mags are another story however, no mags made after 9/13/1994 that hold more than 10 rds (rifle/pistol) or 5 rds (shotgun) are legal to possess in MA. Possession is a felony. Ref: MGL C. 140 S. 131M
Hook up with us in the MA gun laws forum (read the stickies, lots of good info there) on northeastshooters.com to educate yourself on MA gun laws. I actually teach a 5+ hr seminar on the subject here and that covers the intricacies that you don't learn in the class you take to get a LTC in MA.
So do not sell your guns, bring them with you.
