NYC has some of the most draconian gun laws in the country and their murder rates have been decreasing for decades.
Starting in 2005, New York City achieved the lowest crime rate among the ten largest cities in the
United States.
[12] Since 1991, the city has seen a continuous fifteen-year trend of decreasing crime. Neighborhoods that were once considered dangerous are now much safer. Violent crime in the city has dropped by three quarters in the twelve years ending in 2005 with the murder rate at its lowest then level since 1963 with 539 murders that year, for a murder rate of 6.58 per 100,000 people, compared to 2,262 murders in 1990. The murder rate continued to drop each year since then. In 2012, there were 414 murders, mainly occurring in the outlying, low income areas of NYC. Among the 182 U.S. cities with populations of more than 100,000, New York City ranked 136th in overall crime.

In 2006, as part of Mayor
Michael Bloomberg's gun control efforts, the city approved new legislation regulating handgun possession and sales. The new laws established a gun offender registry, required city gun dealers to inspect their inventories and file reports to the police twice a year, and limited individual handgun purchases to once every 90 days. The regulations also banned the use and sale of kits used to paint guns in bright or fluorescent colors, on the grounds that such kits could be used to disguise real guns as toys.
