M1 Garands don't have a remiovable magazine. No matter how you slice it, they do not have a removable magazine. They are therefore NOT ADDRESSED by the NY Law and if any DA were stupid enough to try to make a case about them, he would be laughed out of court.
There are enough real things to worry about on behalf of New York residents without making more stuff up that has no bearing on anything.
Scaring off CMP clients and potential CMP clients when we should be ENCOURAGING folks in NY to buy Garands in order to excercise their Second Amendment Rights is counterproductive to the effort.
