NY City is sending out letters reminding people to comply with the NY SAFE Act. (CLICK HERE FOR THE WHOLE LETTER.) I expect that the NY State police are going to be sending out similar letters to everyone who has a handgun license at some point. (§ 265.36 Unlawful possession of a, (pre 1994,) large capacity ammunition feeding device is a class A misdemeanor. Sentence of imprisonment shall not exceed one year.)
I talked to the NYC Pistol License and they are very confused about what they want you to do. I said that I was keeping the +10 mags out of state and they sounded like they have never though of this possibility. Initially they said that I had to give them a letter saying the address where they were being kept and if I did not have a mag for the gun I should sell the gun because why would I want a gun with no legal mag. Then the officer brought in the Sargent and he said that I had to own a legal mag for the gun and if I was having a hard time getting a legal mag they would give me extra time but I should try to own a legal mag by the April 15th, 2014 deadline.
The following is an excerpt:
The NY SAFE Act prohibits possession of a magazine that has the capacity to hold more than ten (10) rounds of ammunition regardless of when it was manufactured or when it was obtained. It also prohibits possession of a magazine if it is loaded with more than seven (7) round of ammunition, unless you are at a range.
Many license holders own handguns with magazines that have a capacity to hold over ten (10) rounds that were previously legal because they were manufactured prior to September 13, 1994. Those magazines are now illegal. As a result, in order to maintain or renew their licenses, many license holders must surrender or permanently modify their magazines.
If you own such a magazine, the License Division will accept reasonable proof, such as a receipt for the purchase of a magazine that is in compliance, along with proof of disposal of the prior magazine, or certification from a licensed gunsmith indicating that the magazine has been permanently modified to be in compliance with the new law.
Please keep copies of any documents that indicate actual magazine capacity and the date you purchased your new magazine or permanently modified your existing magazine, and be prepared to provide it to the License Division upon request.
Rifles and shotguns have a separate rule in New York City that was not affected by the NY SAFE Act. As per New York City Administrative Code §10-306(b) rifles and shotguns in New York City cannot have feeding devices capable of holding more than five (5) rounds.
