FBI records reviewed by The Associated Press show guns were used in 195 domestic-related killings in New York from 2006 through 2014.
Nationally, 6,235 people were killed in such attacks, with current wives and girlfriends accounting for 75 percent of the victims.
New York's number compared with 637 in California, with a population twice as large, and with 798 in Texas, the second most populous state.
Of the killings in New York, 88 of the victims were girlfriends and 74 were wives. Combined, that was 83 percent of the total. The others included nine boyfriends, seven common-law wives, one ex-husband, eight ex-wives and eight husbands.
Gun ownership rules in New York are among the strictest in the nation and restrict ownership and access by domestic abusers.
