I guess it makes for feel good gun control:

Jersey City has begun requiring gun companies that supply its police department with weapons to disclose more about their business practices, an effort that is being watched by law-enforcement agencies in other cities.

Gun-control advocates and firearms industry representatives said Jersey City is the first municipality in the nation to demand such information. Questions include how firms dispose of old weapons and comply with background-check laws, and whether they make semiautomatic rifles—often called assault weapons—for sale to civilians, according to bid documents viewed by The Wall Street Journal.

The requirement went into effect earlier this year for gun and ammunition contracts worth at least $500,000 for Jersey City’s 800-member police force. The purpose: to try to change the firearms industry through the power of the city purse.

According to the article, several other cities around the country are joining ‘the effort.’
