Modern Firearm Safety Act

The Modern Firearm Safety Act would, in the 18 U.S.C. framework that governs handgun regulation, prohibit any federal, state, or local requirement that a handgun include design features, safety mechanisms, or performance standards that are not mandated by federal statute. The bill adds a new subsection to Section 927, directing that no government body may impose or enforce rules that require handguns in interstate (or foreign) commerce to have features beyond those required by federal law. It specifically lists several features it would block, such as a loaded-indicator, a magazine safety device (which prevents firing unless the magazine is fully inserted), and the ability to imprint identifying information on cartridge casings or projectiles, as well as any device or technology that performs or could be readily converted to perform such functions or that could be attached to a handgun. The sponsor frames the measure as a preemption-and-rights protection effort intended to keep gun design choices aligned with federal standards and to prevent state or local rules from restricting the availability of common-use handguns. In short, the bill aims to prevent states and localities from imposing handgun design features that go beyond what federal law requires, asserting that such requirements limit lawful firearm choices, raise costs, raise safety concerns, and interfere with interstate commerce. The text provided covers the short title, findings, and the core prohibition, but does not include sections detailing penalties or broader regulatory mechanics beyond the amendment to Section 927.
