Once a week on the average, someone gets turned away from entry into Canada for possession of a gun (any gun), and when they return to US customs 10 minutes later, if it's a handgun the local cops get called and the traveler is charged with 2nd degree criminal possession of a firearm unless they have a NY handgun permit (and only NY since NY doesn't recognize any other state's licenses) and the gun or guns in their possession are indicated on their permit by serial number. In the winter it's usually interstate truck drivers that get trapped in this; in the summer it's increased by out-of-state motor home and trailer-towing tourists. Most people from other states aren't aware of NY's intolerance to out-of-state guns. If no criminal intent is evident and it's just ignorance of NY's laws the charges are usually dismissed, but getting your guns back involves FFLs and you'll be without them for a while.
The application for a pistol permit in NY is rigorous and inquiry-driven more than in a lot of other states. Right, some counties are more lax than others, but the bulk of NY's population lives in the counties that aren't lax, and in the counties (boroughs) in NYC, NO civilian has a handgun permit unless they are very well hooked up with the police or other influence. Your license doesn't allow you to even handle my guns unless they show up on your permit as well- so reads the law, which you can ignore at your own risk.
The new plastic licenses that NY issues don't say "carried concealed" as the old paper ones did, it now says "full carry". I'm going to call the local pistol permit office and see if that means OC is now legal in NY.
Anyway, my experience with applying for a pistol permit is as I've described, my sons have had the same experience. The list of when and where CC is illegal in my county includes bars, when consuming alcohol anywhere, in or near schools, if there's an order of protection against you; a muzzle-loading pistol doesn't need to be on your license unless you have the powder, ball and caps (unless its flint-ignited) with you, then it needs to be listed on a pistol permit. New purchases must be on your permit before you take possession, which means after you buy the handgun, you leave the gun shop, go to the county seat with the paperwork, get it registered on your permit, then go back to the gun shop and take possession.
Maybe all of that doesn't seem "restrictive" to you, but it does to me, maybe because I follow all the rules very carefully which encumbers me more than others who don't or aren't required to.
