Slingshots are OK here, but if they are wrist braced the owner is guilty of a 4th degree misdemeanor. Heck, you're guilty of that even if you own "ninja stars" or a host of other things. Meanwhile I can go get a rifle or shotgun, shoulder-braced, with no problem whatsoever Additionally, in NYC the attorney general is cracking down on "assisted open" knives - calling them, by default, dangerous weapons and therefore as illegal to own as a switchblade. And so most merchants are refusing to ship assisted-open knives anywhere in the state. Fortunately, simply taking the brace off the slingshot makes it legal. You're not forced to dispose of the components, they just can't be assembled together.
