This legislation aims to prevent federal, state, and local governments from imposing specific design requirements on handguns that exceed those mandated by existing federal statutes. It asserts that such requirements limit the selection of firearms available to law-abiding citizens, artificially inflate prices, and can introduce safety concerns by altering a handgun's intended design. The bill also finds these mandates to be violations of the Second Amendment and unacceptable restraints on interstate commerce. Specifically, the bill amends federal law to prohibit any governmental entity from implementing or enforcing regulations that require handguns to incorporate certain features as a condition for their lawful manufacture, sale, or receipt. These prohibited requirements include features such as a loaded chamber indicator , a magazine disconnect safety that prevents firing without a fully inserted magazine, or the capability for microstamping ammunition. The prohibition also extends to any device or mechanism designed to perform similar functions or that can be readily converted to do so. This measure seeks to standardize handgun design requirements at the federal level, preventing more restrictive local mandates.
