I believe here in NY it's anything over 22 caliber that is "prudent" power-wise. Also 16" bbl or less.
It used to be handguns 35 cal. and larger but that could mean a 380 auto could be used where a 30/30 Contender couldn't. Even the new law is a bit ambiguous.
This is just a case of the laws not keeping up with the cartridge development.
Long Path, SHHHHHHHHH,keep it under your hat.
