Cavitolo said some of the handguns included .38-caliber revolvers and 9mm semiautomatic pistols. Police also confiscated ammunition for the guns.
Authorities took Gary Granato of Staten Island into custody on charges of weapons possession.
It wasn't immediately clear if Granato had a lawyer. A message left at a phone number listed under his name and the address where the guns were seized was not immediately returned.
Cavitolo said it appeared Granato had been buying the guns over the Internet - but the case remained under investigation.
Cavitolo did not say what Granato was planning to do with the guns.
"We're going to determine his intentions," he said.
