Pennsylvania has always been one of those blue states that oppress gun owner's rights - not quite as draconian as Massachusetts or NY, but pretty bad. I think you can supposedly open carry in most parts of the state too, except Philadelphia, but I've also heard that it's a crap shoot as to if you get hassled for it. Who knows. I'll probably never set foot there again, only time I was there was on a work trip about 22 years ago.
I've lived in Pennsylvania my whole life, and up until recently it was a pretty 2A-friendly State with legal Open Carry and easy-to-obtain Licenses. The only problem was that Open Carry isn't a legal right, (there just aren't any laws against it) up until a couple of years ago, police could hassle you about it, and you couldn't carry onboard vehicles as that was considered a form of concealment, even if you kept it right out in the open. However, awhile back there was actually a legal battle on the issue in which the Judge ruled that police couldn't stop or detain anyone simply because they were visibly carrying a firearm on their person, so that's no longer an issue.
Furthermore, a License to Carry Concealed is as easily obtained as showing up at the Sheriff's Office, (or other designated locations) filling out a minor bit of paperwork, then handing a person at the desk $20.
That said, Governor Tom Wolf is currently living up to his name by suddenly pushing a ton of Gun Control laws, (including a few which were blatantly against existing state laws) so now Polymer 80 frames are restricted (for now) and require an FFL Transfer. Fortunately, he's facing staunch opposition, will most likely fail, and will have only succeeded in making the 2A supporting citizens that much more vigilant.
