Where did you grow up, and when were you born?
I'm still growing up, though in advancing years. From the city...
But to answer what I think is your question -- guns really aren't a part of the city's cultural make-up. They are eschewed by a large portion of the city's residents. The range down by Wall Street basically closed up for lack of business. Holland&Holland and Beretta both have showrooms that cater to the "carriage trade," but aren't what you would call bustling. And, there are a few dealers (aside from those catering to NYPD) tucked away on some second and third story shops on Madison Avenue or out in Queens, Brooklyn, etc.
Although there are a bunch of folks out in Brooklyn/Queens who hunt regularly, there isn't the same emphasis on firearms in NYC as there is in Texas or even Pennyslvania. That is to say, you won't find guns displayed in a livingroom or den. They are more than likely to be tucked away in a basement or closet. The few exceptions to this, of course, are the high end collectors who invest several million in their antique arsenals.
