I belive NY like most states require a plug in the magazine to limit the number shot shell. That shotgun is mag loaded, and may require a restrictive
refit to stay within the law. By the way what is the capacity?
NY allows no more than 5 shell capacity in the gun not counting the chamber. Thus, you could have 5 in the mag and one chambered. The Saiga 12 has 5
and 8 shell mags and comes with the 5 round mag. So capacity wise, it is legal. (unless migratory bird hunting and I believe that is 3 shells, so you
would need the plugs)
