There’s open carry without a license and there’s NO local preemption. You do need a CCW to carry in Philly or in a vehicle.
However, the police do keep a record of gun sales which was found legal since it’s not a “registry.”
As for a VA, there’s a VA in Philly so you can move to the “Philly” Jewish area, whether it’s in Philly proper or right over the border, which will be more friendly for your open carry.
