Here's another thing about New York City Carry permits, they are issued for a specific purpose, like a cash business, where you must prove that you carry a certain amount of cash and make deposits, etc. When I got mine in the early 70's it was $5000.00 in cash at any one time. You then had to get letters from the bank, accountant, tax forms, and on and on. The idea is to make it so hard that you either cannot fulfill cannot prove or just get tired and say screw it.
I had mine over 20 years, now here is the best part. When you sell the business, "or retire, or whatever", you have to turn in your carry permit, since the only reason they gave it to you was to protect yourself when carrying all the cash, which by now is more like 50 grand at a time, not 5 like it was, "which with credit cards and checks" is almost impossible to do. So even after you get it, you have to give it back, the gun gets stamped on the license with the serial number caliber etc. So unless you are a retired cop, or Agent, you don't get to keep your carry forever. It's a privilege in NYC, not a right.
This was as of 1994 when I turned in my guns to the 112 PCT, and had them sent down to a Captain friend of mine in Jupiter, Then I just drove from Ft Lauderdale and picked them up, no problem. You better know all of the laws that apply in the City of NY, if you carry there with a permit other than a NYC carry permit, you are in trouble if caught, this is confusing to newbies so I made it as clear as I can, also there may have been changes made since I moved, I was allowed 2 guns after a few years instead of 1. But the purchase order was how it was done then, you had to first get a purchase order take that to the gun store, buy the pistol and bring everything back ti 1PP, then you were good to go.
