Constitutional Concealed Carry Reciprocity Act of 2025 amends Title 18 of the U.S. Code to grant nonresidents of a state that allows concealed carry the right to possess or carry a concealed handgun in that state. The provision requires the individual to hold a valid state license or permit that authorizes concealed carry, a photo identification document issued by the U.S. government or a state, and no federal prohibition on firearm possession. It applies only to states that either allow residents to apply for a concealed‑carry license or do not prohibit concealed carry for residents. The act explicitly preserves state authority to prohibit or restrict firearms on private property or on state and local government property, and it does not override existing state laws that allow such restrictions. A carrier who complies with the federal requirements may not be arrested or detained for violating state law unless probable cause exists that the carrier is acting outside the scope of the federal provision. In criminal proceedings, the prosecution bears the burden of proving beyond a reasonable doubt that the carrier did not meet the federal conditions, and a successful defense may award the defendant reasonable attorney’s fees. Individuals deprived of the rights granted by this section may file civil actions against any person or governmental entity that causes such deprivation, with the court awarding damages and attorney’s fees. The bill defines a handgun to include the firearm, its magazine, and loaded ammunition, and exempts carriers from the prohibitions of 18 U.S.C. § 922(q). Carriers may also carry concealed handguns on certain public lands, including: units of the National Park System units of the National Wildlife Refuge System public land under the jurisdiction of the Bureau of Land Management land administered by the Army Corps of Engineers land administered by the Bureau of Reclamation land administered by the Forest Service The amendments take effect 90 days after enactment.
