So held the Philadelphia Court of Common Pleas, in NRA v. City of Philadelphia, 2008 Phila. Ct. Com. Pl. LEXIS 159, decided June 30 but just put up on Lexis. I hadn't seem much coverage of the subject, so I thought I'd note it, though the decision was a month old.
The court held plaintiffs (which included individuals as well as the NRA) lacked standing to challenge to a city ordinance requiring owners "to report to police a lost or stolen firearm within twenty-four hours after the loss or theft is discovered," an ordinance aimed at enforcing court orders banning weapons possession in domestic abuse cases, and an ordinance temporarily banning gun possession by people found to have been "exhibiting conduct indicating a clear risk that they may inflict personal injury on themselves or others."
