What is an illegal weapon?
That should not be possible except when it has been used in the commission of a crime and is seized for evidence.
"What is an illegal weapon?"
I'd like to know what an "illegal weapon" is in NY. Does that mean "unregistered"? Without a concealed carry permit in NY?
What ARE the handgun laws in NY, not just NYC? Permitted anywhere?
One for which there is no permit. You, frankly, have no business carrying a gun in a city the density of New York unless you are a cop, a security guard, or have a unique security situation.
