Tyreese, yes it is. However, I always advocate checking with your local Law Enforcement Authority as their interpretation of the law will be what ultimately matters.

Yes, but why would you want to carry such a bulky firearm, when a pistol you can easily conceal is more practical. This style is best suited for home defense instead of personal defense away from home. Always check your local laws; as they are constantly changing.

Tyreese, This is a legal pistol, handgun in PA. You only need a license to carry in PA to conceal carry. No concealment on this firearm. If you want to open carry no permit needed. To summarize, open carry is legal in Pennsylvania without a License To Carry Firearms except in "cities of the first class" (Philadelphia) and vehicles where a License To Carry Firearms is required to do so.
With that said, we would like to point out that there is much debate among firearm owners about whether openly carrying firearms is really a good idea. While we will leave that choice to the individual we will state that in many urban areas (namely Philadelphia) doing so will draw unwanted attention from law enforcement that may include (but not be limited to) the following repercussions:
Being stopped and questioned by law enforcement.
Having your License To Carry Firearms seized and sent back for revocation.
Being arrested either improperly or for other charges like disturbing the peace or creating a public nuisance.
