The Safe Storage Saves Lives Act requires that every firearm sold in the United States come with a compatible gun lock provided by the seller. The bill expands an existing law that only applied to handguns to cover all types of firearms, and it applies to all sellers, not just licensed dealers. Sellers who fail to provide or offer a compatible lock face civil penalties of up to $1,000 per violation. The legislation includes a sense-of-Congress provision recommending that any fines collected be used to distribute free or reduced-cost gun locks to the public or to fund awareness campaigns about safe storage practices.
