A quick Westlaw search using the information provided by Fishing_Cabin turned up: ALLEGHENY SPORTSMEN'S LEAGUE, Kim Stolfer, et al. v. Tom RIDGE, et al., cited as: Allegheny Sportsmen's League v. Ridge, 790 A.2d 350 (Pa. Commw. Ct. 2002) aff'd sub nom. Allegheny County Sportsmen's League v. Rendell, 580 Pa. 149, 860 A.2d 10 (2004).

I didn't read the case in depth, but my very cursury review shows that the PA Supreme Court looked at it this way: The statute in question prohibits the creation of a registry of firearm ownership. A firearms ownership registry would encompass all firearms, including both handguns and long guns, and would have to include every transfer. What the PA did was create a registry of sorts, but it's a registry of the sales of handguns. That's different, and not prohibited by the statute at issue.
