Expands federal firearm prohibitions to cover certain current and former dating partners and their children, and creates a new federal misdemeanor definition of stalking that can disqualify someone from possessing firearms. The bill updates federal definitions and the statutory firearms‑possession bars to add covered dating partners and clarify coverage for children of those partners, and it specifies what elements a misdemeanor stalking offense must include to count as a disqualifying conviction.

The changes amend the federal firearm definition and prohibition provisions to (1) explicitly include some dating relationships and their children among people barred from possessing firearms, (2) establish a misdemeanor stalking offense with defined elements, and (3) set rules for when a misdemeanor stalking conviction triggers the federal gun‑possession ban.
