Firearm Owners Against Crime v. City of Pittsburgh, 2022 Pa. Commw. LEXIS 67 (May 27, 2022) (McCullough, J.) The Pennsylvania Uniform Firearms Act, found at 18 Pa. C.S. 6120(a) prohibits a municipality, township, etc. from in any way regulating ownership, possession, transfer or control of guns or ammunition. Here, the City of Philadelphia prohibited assault weapons and large capacity magazines. The court, somewhat apologetically, said that the city code is preempted by state law which completely occupies the field of gun control in Pennsylvania.
