Precise figures about the numbers of illegal firearms in the European Union (EU) are lacking, but several indicators point to their widespread availability and accessibility. According to the Small Arms Survey, over half of the estimated total number of firearms held by civilians in the EU in 2017 were unlicensed. While most of these citizens had no criminal intentions, their illicit firearms could be used for self-harm or domestic violence, or end up in the hands of criminals or terrorists. Most criminals and terrorists have more sophisticated ways to get hold of illicit firearms. They can be trafficked from source countries, diverted from legal supply chains, illegally manufactured or assembled in the EU, converted from legally available weapons, or sourced on the internet. Firearms seizures suggest that the EU illicit firearms market is made up mostly of shotguns, pistols and rifles, with converted or convertible weapons also appearing frequently. Illicit firearms trafficking is driven by criminal demand, with organised crime groups that engage in firearms trafficking also involved in other forms of criminality. The EU considers illicit firearms a key crime threat precisely because they are used in many crimes and terrorist attacks. Even people who lack extensive criminal connections can access illicit firearms due to increased online trafficking and the availability of easy-to-convert weapons. The EU is actively involved in addressing the threat posed by illegal firearms by means of legislative and policy measures, and provides operational assistance to the Member States in the fight against firearms trafficking. The EU is also active in the international fight against firearms trafficking, working closely with the United Nations (UN) in its work to combat the proliferation of small arms and light weapons and engaging in the UN's global firearms programme. Although the export of arms remains a national competence, the EU has defined common rules governing the control of exports of military technology and equipment and works actively with third countries that are viewed as source or transit countries for illicit firearms. This is an update of a briefing by Ann Neville, published in 2022.

Why GAO Did This Study The U.S. Southwest Border Counternarcotics Strategy: 2020 identified the trafficking of firearms from the U.S. into Mexico as a threat to the safety and security of both countries. The Mexican government has estimated that 200,000 firearms are smuggled from the United States each year. GAO was asked to report on U.S. efforts to counter firearms trafficking to Mexico. This report examines (1) the extent of U.S. agencies’ knowledge about firearms trafficking to Mexico and (2) U.S. agencies’ efforts to disrupt this trafficking and the extent to which they have assessed those efforts. GAO reviewed firearms tracing data, related analysis, and program information for fiscal years 2014 through 2020. GAO also interviewed U.S. and Mexican officials. This is a public version of a sensitive report that GAO issued in December 2020. What GAO Recommends GAO is making eight recommendations, including recommending that ATF and ICE analyze additional information about the trafficking of U.S.-sourced firearms to Mexico and that ATF, ICE, CBP, and State develop performance measures to assess the results of their efforts to disrupt this trafficking. The agencies concurred with GAO’s recommendations.
