The way i read it, it appears a pistol grip could be considered an assault weapon. Look in Miscellaneous. Just ordered my steel side folding stock w/ pistol grip for the ole' 870. Should be here soon
To the best of my recolection, as long as the overall length complys with Fed rules it is ok.. NYC being a different breed of cat. I live in upstate,so I am not familiar with the bastard part of the State.
OK in NYS.
Not OK in NYC.
Since I have seen them sold in Nassau county gunshops I must assume they are legal there.
PS...If you buy one make it a 20 guage.
