Gun show promoters across New York State have agreed to provisions intended to ensure buyers’ background checks are done, according to New York’s attorney general.

State Attorney General Eric Schneiderman says his office has come to an agreement with more than 20 gun show promoters across New York on what he says are “model gun show procedures.”

Under the agreement, all guns brought to gun shows by private sellers are to be tagged so that those running the shows can tell if the weapons were sold and that background checks were, Schneiderman’s office said in a statement.

The agreement stems from a look into gun shows by Schneiderman’s office in 2011 that he said showed a large number of private sales were made without background checks.

“Gun violence is everyone’s concern, and I’m proud that we’ve worked with gun show operators to create simple procedures to ensure that deadly weapons don’t make it into the hands of felons, terrorists, the dangerously mentally ill, or anyone else who could not pass a background check,” the attorney general said.

The 23 operators in the agreement are set to run more than 50 shows and gun auctions in New York this year, which account for more than three-quarters of the shows in the state.
