This is the kind of case where we would win at the SCOTUS level. 100%.
We'd lose in NY district court, and in the 2nd circus, obviously...because liberal judges are retarded and dishonest...But SCOTUS, even with the current make up, would absolutely call this unconstitutional.
And it is such a clear cut, simple, focused, narrow question - the kind of case SCOTUS loves to take.
Is it constitutional to require the surrender of one's 4th amendment rights, in order to exercise their 2nd amendment rights?
If someone would just refuse the inspection based on 4th amendment grounds, and they actually had their 2nd amendment right to own a handgun revoked, a Supreme Court win would almost be guaranteed.
It would also call into question the fact that one needs to get a license simply to OWN a handgun and possess in the home - which is, according to Heller, a core individual right.
