According to Pa. Const. Art. 1, § 21, the right of the citizens to bear arms in defence of themselves and the State shall not be questioned.
A purchaser has the right to check the records related to a seller’s license and documents related to the firearm that s/he intends to purchase. A transfer application or record of sale has to be signed by the purchaser with the seller of a handgun. Transfer application or record is not necessary to transfer a rifle or shotgun. Purchases of antique firearms through dealers are exempt from the requirements regarding transfer.
Any person who is prohibited by law from possession should not attempt to purchase a firearm. A Pennsylvania resident who is lawfully eligible to purchase, possess, sell, or transfer a firearm shall not be prohibited from purchasing or otherwise obtaining a rifle or shotgun in a jurisdiction outside the Commonwealth. Persons convicted of drunk driving three times within a five-year period may possess but may not purchase a firearm. Any person being kept away from purchasing and possessing firearms due to certain disabling convictions may apply to the Court of Common Pleas for restoration of his or her firearms rights. The state police shall provide free brochures summarizing state law relating to the buying, selling, and transferring of firearms to each individual who purchases a firearm from a licensed dealer.
