Crime Gun Tracing Modernization Act of 2025

Requires the ATF National Tracing Center to build and keep electronic, searchable databases of specified firearms transaction records and allows licensed dealers to provide the Center with electronic access to their records. The database must be searchable by certain transaction fields, must not contain personally identifiable information, may be used only for limited, specified law‑enforcement purposes, allows voluntary transfer of older paper records after 10 years, and requires regular audits by the Government Accountability Office; it takes effect upon enactment.
