"Original" like "in the beginning" in New York? If that is what you mean, then the first real NY laws restricting concealed carry began in the 1880s...the law required that any town, village or city if they chose, could require a license to carry a pistol. It was written for New York City...but the license was issued by any Magistrate for I think $1-$3 to anyone who asked, and the fees contributed to the Policemen's Pension. There was no "proper cause" or "good moral character". You wanted to carry a pistol, you saved up the fee and applied for the license. Again, it only applied where the village or city chose to implement this license. As far as I know, it was generally only in NYC. This was changed in 1911, with the Sullivan Law.What was the original criteria for consealed carry?
The Sullivan Law was different. It was mandatory statewide. It required a license just to possess a pistol. If you wanted to carry concealed, you required a reason acceptable to a licensing official whether you need it or not. You needed references for "good moral character" and at first, the license was "good throughout the state", inc. NYC. At first any Judge or Justice of the Peace anywhere in the State could issue a license and many did, for consulting fees of course, and the licenses were good even in NYC. Many of our most civic minded citizens belonging to esteemed charitable groups such as the Five Points Gang, the Monk Eastman Gang and later Jewish and Italian mobsters, all took advantage of the ability to obtain licenses from Judges anywhere in the State. This changed in 1934, when the law was revised that a license to carry in NYC, had to be issued by the Commissioner of the NYPD.
I'm almost positive that 1934 (I'm not certain) was also the year that you were required to apply in your county of residence, and that was when restrictions became common going forward, because it empowered local officials...you could no longer thumb your nose at some obstinate local licensing official who would not issue a license, and just simply go find another Judge anywhere in the State.
It's in a lot of ways better today. If you read some of the court cases going back to even WWII, you'll find people who were denied a license even just for target shooting and losing in Court. Today, you'll generally not be denied a license to carry while target shooting.
