As of yesterday, PA's AG has changed reciprocity for all agreements to Resident Permits only, and has KILLED reciprocity with VA. (note: VA still honor's PA's permit.)
My understanding of this for me is, as a NJ resident I will no longer be able to conceal carry in PA (again!)
Everyone else, if you're not a PA resident and you visit that state, please take a moment and verify what your status is in terms of legal carry.
Note: PA "allows" open carry on ANY permit (you can go find the statute) and allows "concealed" inside a vehicle.
