Arrested For Owning Pepper Spray In Nyc

Got arrested for owning a mace pepper spray device (pepper gun 2.0) and got hit with charge 10-131 (E). It just shoots a stream of liquid, no pellets or objects - just capsaicin.

The arresting officer kept reminding me how lucky I am I didn't get boomed and that I had no business owning this but it's just pepper spray and crime is absolutely nuts here why wouldn't I? I bought it in Long Island I had no idea it's illegal in NY.

I just got out of the precinct and I'm wondering, is this actually a serious charge in NYC? I mean I felt compelled to buy it considering how crazy crime is especially for delivery drivers, I keep it in my car God forbid I have an irate person try to hurt me since I deliver food in bad neighborhoods. Am I actually looking at time? Please help.
