The Department of Justice’s decision to stop defending the Postal Service’s blanket prohibition on carrying firearms on federal property is more than a procedural footnote—it’s a quiet but unmistakable signal that the administrative state is recalibrating after Bruen. For years the Postal Service leaned on a 1972 regulation that treated every post office like a sensitive place, even though the Supreme Court’s history-and-tradition test has made such categorical bans harder to sustain. By walking away from the defense, DOJ is effectively conceding that the old “government property equals gun-free zone” shortcut no longer passes constitutional muster, and lower courts are now free to apply the same scrutiny that has already toppled similar restrictions in other contexts.

That shift carries immediate tactical implications for the 2A community. Litigants challenging analogous bans at VA hospitals, national parks, or federal courthouses now have fresh precedent to cite, and the Postal Service itself may quietly rewrite its rules rather than risk an adverse ruling that could cascade across the entire federal campus. More broadly, the move underscores how enforcement priorities at Main Justice can change with a single administration, reminding activists that durable victories still require legislation or Supreme Court clarification rather than hoping the next set of political appointees will simply stop enforcing bad rules.

For everyday carriers the practical takeaway is straightforward: the map of where you can lawfully carry is expanding, but only where citizens and litigators keep pressing. The DOJ’s retreat is an invitation to finish the job—pushing courts to finish what Bruen started and ensuring that “post office” stops being shorthand for “no guns allowed.”
