There is no special law for that gun unless it has a thumbhole or pistol grip stock.
The barrel is over 18" and the total length is over 26", it's just a plain old shotgun.
Still happily answering to the call-sign Peetza.
You do not HAVE a soul. You ARE a soul. You HAVE a body.
He is no fool who gives what he can not keep to gain what he can not lose.
