PITTSBURGH — Pittsburgh Mayor Bill Peduto will sign the city’s new gun legislation "early next week," a spokesperson in the mayor’s office said. If that happens, the Firearms Industry Consulting Group, in Bechtelsville, will likely file a class-action lawsuit on behalf of four gun rights organizations in the state: the Allegheny County Sportsman’s League, Firearms Owners Against Crime, Firearms Policy Coalition and Firearms Policy Foundation. Here’s the statement released by attorney Joshua Prince: "Thus, if the Mayor signs these, or any other, proposals involving firearms or ammunition, Allegheny County Sportsmen’s League, Firearm Owners Against Crime, Firearms Policy Coalition, and Firearms Policy Foundation, as well as several individual plaintiffs, will file suit, with a request for attorney fees and costs, and requesting that District Attorney Zappala file criminal charges for violations of 18 Pa.C.S. 5301, 6120." The Pittsburgh City Council passed three bills Tuesday banning the use of the AR-15 semi-automatic rifle and large capacity magazines, which are also used in 9 mm handguns. Members of the City Council and supporters of the city’s new gun legislation say they’re prepared to take on the legal battles.
