Modern Firearm Safety Act

Legislative Summary: H.R. 4676 - Modern Firearm Safety Act

Overview

The Modern Firearm Safety Act (H.R. 4676) is a federal legislative proposal designed to prevent state and local governments from imposing specific design and safety requirements on handguns that are not already mandated by federal law. The bill seeks to establish federal preemption over state-level mandates regarding firearm features, arguing that such requirements restrict consumer choice and interfere with interstate commerce.

Purpose and Intent

The primary intent of this bill is to standardize the legality of handgun designs across the United States. The legislation explicitly states that state-mandated features not typically found on common handgun models:
* Limit the selection of firearms available to law-abiding citizens.
* Artificially increase the cost of firearms.
* Create safety concerns by altering the original design and function intended by the manufacturer.
* Interfere with interstate commerce and violate the Second Amendment.

Key Provisions

The bill amends Title 18, United States Code, Section 927, to prohibit any federal, state, or local agency from implementing or enforcing regulations that require handguns shipped in interstate or foreign commerce to include specific features unless those features are required by federal statute.

Specifically, the Act prohibits mandates for the following:
* Loaded Chamber Indicators: Devices that signal whether a round is currently chambered.
* Magazine Safety Mechanisms: Mechanisms that prevent a firearm from discharging unless the magazine is fully inserted.
* Ballistic Imprinting: The requirement for firearms to imprint identifying characters onto cartridge casings or projectiles when fired.
* Adaptability: Any technology designed to perform the functions above, or any design that allows such devices to be easily attached or converted.

Who is Affected?

• State and Local Governments: Agencies would be stripped of the authority to enforce "safety feature" mandates that exceed federal standards.
• Firearm Manufacturers: Manufacturers would no longer need to create state-specific versions of handguns to meet varying local design requirements.
• Consumers: Handgun buyers would have access to a broader range of firearm models regardless of the state in which they reside.

Procedural Status

• Introduced: July 23, 2025
• Current Status: Referred to the House Committee on the Judiciary.
• Sponsorship: Introduced with a broad coalition of co-sponsors, primarily targeting the removal of state-level regulatory barriers to firearm sales.
