The Justice Department filed an unopposed motion on July 16, 2026 to voluntarily dismiss its Fifth Circuit appeal in Firearms Policy Coalition v. Blanche. The motion runs two sentences with no substantive explanation. That is the procedural equivalent of the government conceding it does not want an appellate court to reach the merits. Once the Fifth Circuit enters that dismissal, the appeal is erased without any appellate ruling and Judge O'Connor's district-court judgment stands as the final word.

The district-court judgment is a permanent injunction issued September 30, 2025. Judge O'Connor, sitting in the U.S. District Court for the Northern District of Texas, held that 18 U.S.C. § 930(a) as applied to ordinary post offices fails the Supreme Court's Second Amendment analysis under New York State Rifle and Pistol Association v. Bruen (2022). The statute prohibits knowingly possessing a firearm in a federal facility. The regulation the postal service pushes on top of it, 39 C.F.R. § 232.1(l), extends that prohibition to postal property and vehicles on postal property. Neither, the court held, is consistent with the historical tradition of firearms regulation the government must produce to survive Bruen's text-and-history test. The injunction blocks enforcement of both provisions against SAF and FPC members at ordinary post offices, and it extends to surrounding postal property including parking lots.

Two things make the July 16 withdrawal significant beyond the case itself. First, once the Fifth Circuit enters the dismissal there will be no Fifth Circuit opinion for other circuits to distinguish or follow. The ruling does not directly help a Ninth Circuit or Eleventh Circuit carrier who wants to challenge the same statute in their own jurisdiction, but it also does not create adverse precedent for the pending challenges elsewhere. Second, the withdrawal signals this Justice Department's appellate posture on Bruen-based federal-facilities litigation: the same DOJ that walked away from defending 18 U.S.C. § 930(a) here is running Bruen the opposite direction in its own affirmative Second Amendment suits against Virginia and California. One posture withdraws federal defense of a federal-facilities carry ban; the other affirmatively attacks state-level assault-weapon and handgun-sales bans.

The injunction protects members of the Firearms Policy Coalition and the Second Amendment Foundation. Not every gun owner. Not every concealed carry permit holder. Not every American. This is the single most-overlooked part of the coverage story, and getting it wrong is the difference between a legal errand and a federal misdemeanor under 18 U.S.C. § 930(a).

The scope language matters. Judge O'Connor's order, as reported by both the Second Amendment Foundation and NRA-ILA, enjoins enforcement against “the named plaintiffs and all present and future members of SAF and FPC.” That phrasing is deliberate and has two practical consequences. First, joining either organization after the ruling still confers protection, because the order sweeps in future members. Second, membership lapses matter: a member whose SAF or FPC dues expired last quarter is no longer covered and is prosecutable the same as a non-member. Keep the membership current.

Enrollment is fast. FPC membership through firearmspolicy.org starts at $25 per year. SAF membership through saf.org starts at $15 per year. Both take effect on payment. Both send an electronic confirmation. There is no waiting period, no residency requirement, and no distinction between annual and life-member coverage for purposes of this injunction. If you are already a member of one, you are protected; if you are not, joining before you carry into a post office is the entire compliance step.

For a real-time challenge, the practical evidence question is whether you can demonstrate membership on the spot. Save the membership confirmation email as a PDF or screenshot on your phone. Both organizations also mail physical member cards on request. A postal inspector or officer who has a question is not going to have real-time access to SAF or FPC's membership rolls, so the burden of showing coverage falls on you. Treat it the same as carrying proof of your concealed carry permit.

The injunction covers ordinary post offices and their surrounding postal property, including parking lots. The “parking lot” scope matters in practice because a firearm locked in your personal vehicle at postal property was a chargeable offense under 39 C.F.R. § 232.1(l) before the ruling. The injunction resolves that scenario for SAF and FPC members. Walking from your car to the counter with a holstered pistol at an ordinary standalone post office is covered conduct.

The injunction does not cover post offices inside federal buildings that house other federal functions. If the post office window is inside a federal courthouse, a Social Security Administration office, a passport office, or a federal government office building with a security screening checkpoint, the underlying 18 U.S.C. § 930 prohibition on firearms in that federal facility is still enforced against you, even as an FPC or SAF member. Those buildings usually have magnetometers at the entrance, so the practical enforcement mechanism is clear: you cannot bring a firearm through the screening.

Post offices on military installations are also outside the injunction. Military bases run under separate federal installation-access rules and their own carry regulations regardless of the SAF and FPC injunction. If you access a base for your postal errand, the base rules govern.

The safest rule at the counter: if the facility looks like anything other than a standalone USPS branch on a public street, treat it as uncovered and leave the firearm secured in your vehicle. Postal inspectors have federal law enforcement authority and the underlying statute carries a federal misdemeanor penalty (up to one year imprisonment). For a broader look at where carry actually lands legally, our state legality matrix tracks the concealed-carry framework and sensitive-place carve-outs each state layers on top of federal rules.

The practical carry problem at a post office is short-duration carry into a facility with unpredictable dwell time. You are walking in, standing in a line that could run five minutes or twenty, executing a transaction at the counter, and walking out. The whole errand is 10 to 30 minutes with a firearm on your body the entire time. The setup that works is one that conceals under a t-shirt, does not print when you lean over the counter to fill out a customs form, and stays on your body from the driveway to the counter and back.

For most carriers that means one of three configurations. First, appendix inside-the-waistband with a claw-equipped holster (Tenicor Certum3, Tulster Oath, Vedder LightTuck) paired with a Glock 19, P365 X-Macro, or Hellcat Pro. Second, micro-compact pocket carry with a P365, Hellcat Micro-Compact, Glock 43X, or S&W Bodyguard 2.0 in a leather or KYDEX pocket holster. Third, strong-side inside-the-waistband behind the hip with a fullsize duty pistol under a looser-fitting overshirt. Our best concealed carry pistols guide covers current top picks by frame size, and the concealed carry holster guide covers the specific IWB, appendix, and pocket rigs that pair with those pistols.

Avoid setups that require reholstering in the parking lot. Any workflow that has you removing the firearm at the vehicle and putting it back on when you get home is a workflow with a reholstering step somewhere near the front door, and every reholster is a negligent-discharge opportunity. The stated purpose of this injunction is that you do not have to do that: you carry from home to the counter to home, on-body, the whole time.

A note on backpack and off-body carry: the injunction covers firearms on your person and in your personal vehicle in the parking lot. It does not create a special rule about backpacks or off-body carry beyond what state and local law already allow. If your state permits off-body carry with a CCW, an off-body setup is legal to bring into the post office as an FPC or SAF member the same as an on-body setup. For hiking-and-errands mixed use, our backpack gun setup guide covers the mechanics.

18 U.S.C. § 930(a) makes it a federal offense to knowingly possess a firearm in a federal facility. The maximum penalty is one year of imprisonment, a fine, or both. The Postal Service's own regulation, 39 C.F.R. § 232.1(l), extends the prohibition to any postal property and to vehicles on postal property, and it authorizes postal inspectors to enforce it. Together those two provisions have been the federal-enforcement foundation for the post office firearms ban for decades.

NYSRPA v. Bruen (2022) rewrote how federal courts analyze Second Amendment challenges. The old two-step means- end scrutiny is gone. Under Bruen, if conduct is covered by the Second Amendment's plain text (“keep and bear arms”), a regulation is presumptively unconstitutional unless the government affirmatively identifies a founding-era or Reconstruction-era historical analog that regulated comparable conduct in a comparable way. Judge O'Connor's September 2025 ruling applied that framework and held that carrying a firearm at an ordinary post office is protected conduct and that the government failed to produce a historical tradition of restricting arms at analogous government facilities. For a fuller picture of how Bruen-era rulings are reshaping firearms law, see our coverage of the Supreme Court's Viramontes cert grant and the Third Circuit's New Jersey ruling.

The takeaway for carriers is narrow but real: SAF and FPC members are covered at ordinary post offices; non-members are still exposed to the underlying federal statute; the statute itself remains on the books for future litigation to test on behalf of everyone else.

A concealed carrier who is a current member of the Firearms Policy Coalition or the Second Amendment Foundation can now legally carry a firearm into an ordinary U.S. Post Office and its parking lot under Judge O'Connor's September 30, 2025 permanent injunction. DOJ moved to voluntarily dismiss its Fifth Circuit appeal on July 16, and once the Fifth Circuit enters that dismissal there is no appellate opinion to reverse or distinguish. Non-members are still subject to 18 U.S.C. § 930(a) and can be prosecuted for the same conduct.

For anyone who runs regular errands through the USPS, this is roughly $15 to $25 a year to solve. Join SAF or FPC before you carry, keep the membership current, keep proof of membership on your phone, and treat non-standalone facilities (federal buildings, military installations) as uncovered. The concealed-carry setup does not change: use the same pistol, same holster, same carry-position you already carry with day-to-day; the legality of walking through the post office door is what changed.
