I have a friend who lives in MA that purchased a glock through a police dept. also in MA. The glock is a confiscated duty weapon from a PT cop who had a restraining order taken out on him so he had to forfeit the gun blah blah blah. Now my friend is unsure of whether he needs to send his copy of the FA-10 into the firearm registry or if the police dept. he bought it from will take care of it. It is the seller's responsibility in all cases (with the exception of out of state purchases) to send in the FA-10, correct?
