The Protection of Lawful Commerce in Arms Act (PLCAA) has long been a cornerstone of protection for firearms manufacturers and sellers, shielding them from liability when their products are misused in crimes. But recent litigation, including the Pennsylvania Supreme Court’s decision in Gustafson v. Springfield, Inc.,1 shows how litigants continue to test the boundaries of this federal law. While the ruling ultimately upheld the PLCAA’s protections, the case is a reminder of the ongoing scrutiny the law faces—and why it remains essential for the firearms industry.
