Title 3— 

The President 

Executive Order 14127 of September 26, 2024 

Combating Emerging Firearms Threats and Improving SchoolBased Active-Shooter Drills 

By the authority vested in me as President by the Constitution and the 

laws of the United States of America, it is hereby ordered as follows: 

Section 1. Policy. During 2020, the last year of the prior administration, 

homicides in the Nation increased nearly 30 percent over the previous 

year—the largest 1-year increase in murders ever recorded. After that, the 

Vice President and I took action to reduce gun crime and other forms 

of violent crime. By the middle of 2022, we had already taken more executive 

action to reduce gun violence than any other administration at that point 

in time. On June 25, 2022, I signed into law the Bipartisan Safer Communities 

Act (Public Law 117–159)—the most significant new gun violence prevention 

law in nearly 30 years. Rates of homicide in the United States are falling 

at one of the fastest rates ever recorded. Year-over-year comparison shows 

that 2023 had one of the largest declines in the homicide rate in recent 

history. This life-saving progress has continued in 2024. While we have 

made great progress, much more work remains to be done to reduce gun 

violence and save lives. 

It is the policy of my Administration to coordinate across executive departments and agencies (agencies) to reduce gun violence and save lives. This 

order directs enhanced coordination for two key challenges: combating emerging firearms threats and understanding and improving school-based activeshooter drills. 

One way to continue the progress on reducing gun violence is to stay 

ahead of emerging violent crime threats involving firearms. My Administration has always taken these threats seriously. In April 2021, one of my 

Administration’s first executive actions to reduce gun violence was directed 

at stopping the proliferation of firearms without serial numbers, often referred 

to as ‘‘ghost guns.’’ To expand these efforts, the Bureau of Alcohol, Tobacco, 

Firearms, and Explosives (ATF) of the Department of Justice established 

an Emerging Threats Center, which focuses ATF’s resources on identifying 

developments in illicit firearm marketplaces, including the use of new technologies to make and unlawfully distribute undetectable firearms and devices 

that convert semiautomatic firearms into illegal machineguns. The Vice President and I strongly disagreed with the Supreme Court’s decision to strike 

down an important gun safety regulation on bump stocks—the device used 

in the shooting at a crowded music festival in Las Vegas—and called on 

the Congress to clarify that this dangerous accessory is a machinegun. 

The Court’s decision addressing bump stocks did not alter the statutory 

prohibition on machinegun conversion devices, which are prohibited for 

non-governmental possession even when not installed on a firearm. The 

threat posed by the continued proliferation of these devices is particularly 

acute. These devices enable semiautomatic firearms, including easily concealable handguns, to match or exceed the rate of fire of many military machineguns with a single engagement of the trigger—up to 20 bullets in one 

second and 1,200 rounds in one minute. From 2017 through 2021, ATF 

recovered 5,454 of these devices—a 570 percent increase over the previous 

5-year period. These devices are often illegally imported or illegally made 

on a 3D printer.

Unserialized, 3D printed firearms—which can be used for illicit purposes 

such as gun trafficking, possession by people convicted of felonies or subject 

to domestic violence restraining orders, or unlawful engagement in the business of manufacturing or selling firearms—are another emerging threat. These 

firearms can be 3D printed from computer code downloaded from the internet 

and produced without serial numbers, which law enforcement uses to trace 

firearms recovered in criminal investigations. Some 3D printed firearms 

can be rendered undetectable by magnetometers used to secure airports, 

courthouses, and certain events. 3D printing technology is developing quickly, which can cause the safety threat of 3D printed firearms to suddenly 

increase. 

In addition to the threat of domestic crime, these emerging firearms threats 

pose a significant risk to the national security and foreign policy interests 

of the United States. Many foreign countries have heavily regulated automatic 

weapons and 3D printed and undetectable firearms. The wide availability 

of these emerging firearms threats would undermine other nations’ gun 

laws and the safety and security of our allies. Technical data and software 

for 3D printed firearms and machinegun conversion devices can be used 

by international gangs, criminals, and terrorists in a manner contrary to 

United States national security and foreign policy interests. 

Multiple agencies have the authority to help stop the proliferation of these 

emerging threats, and it is the policy of the United States to work collectively 

across agencies to identify threats, engage in information sharing, and work 

together to develop and implement effective strategies to combat these threats. 

Authorities that can address emerging firearms threats extend beyond the 

Gun Control Act (Public Law 90–618) and the National Firearms Act (Public 

Law 73–474). Focused and enhanced coordination is needed to ensure a 

unified and robust strategy for enforcing existing legal authorities and using 

every available tool and resource. This interagency effort will build on 

the life-saving work that has occurred to date to stop the proliferation 

of machinegun conversion devices, including the ongoing efforts at the Department of Justice and ATF. 

My Administration also has invested significant resources in school safety 

and has taken steps to keeps firearms out of schools. These steps have 

focused on preventing unauthorized access to firearms for youth and individuals in crisis; supporting schools that are implementing evidence-based safety 

and gun-violence prevention and intervention solutions; and addressing the 

mental health needs of students, particularly those impacted by gun violence. 

Keeping students and educators, including teachers and other school personnel, safe from gun violence in their schools is a top priority for my 

Administration, but there is more to do to make our schools safer. Since 

the mass shooting at Columbine High School in Colorado in 1999, according 

to one analysis, there have been more than 400 school shootings that exposed 

more than 375,000 students to gun violence. Exposure to school shootings 

takes a terrible toll on students and educators. A nationally representative 

study found that 51 percent of 14- to 17-year-olds in the United States 

worry about school shootings. 

The majority of States require schools to conduct active-shooter drills for 

students and educators. About 95 percent of K–12 public schools in the 

United States conduct lockdown drills, which include drills to prepare 

for an active-shooter situation. These drills vary widely in their approach, 

and many parents, students, and educators have expressed concerns over 

the effectiveness of and trauma caused by some approaches to these drills. 

Despite their ubiquity, there is very limited research on how to design 

and deploy these drills to maximize their effectiveness and minimize any 

collateral harms they might cause. While additional research is ongoing, 

it is difficult to conclusively determine which specific practices are most 

effective in preparing schools for active-shooter incidents, preventing injuries

Federal Register / Vol. 89, No. 191 / Wednesday, October 2, 2024 / Presidential Documents 80347 

and fatalities, and minimizing any associated psychological impacts or traumas. The Department of Justice, the Department of Health and Human Services, the Department of Education, and the Department of Homeland Security 

continue to work together on a range of school safety issues, including 

the beginnings of research into these important questions. It is time for 

these agencies to extend their efforts to help schools better design and 

conduct effective and age- and developmentally appropriate active-shooter 

drills. 

Sec. 2. Definitions. For purposes of this order: 

(a) The term ‘‘machinegun’’ has the meaning given by 18 U.S.C. 921(a)(24) 

and 26 U.S.C. 5845(b), and includes a ‘‘machinegun conversion device,’’ 

which is any part designed and intended solely and exclusively, or combination of parts designed and intended, for use in converting a weapon into 

a machinegun. 

(b) The term ‘‘undetectable firearm’’ means a firearm as proscribed by 

18 U.S.C. 922(p). 

(c) The term ‘‘3D printing’’ refers to the additive manufacturing process, 

during which producers transmit digital designs to 3D printers. The computerized design guides the fabrication of products, building them up layer 

by layer rather than cutting away from a large block of existing material 

as in most traditional manufacturing. This term includes additive manufacturing technology used to produce a firearm, firearm frame or receiver, 

or machinegun conversion device. 

Sec. 3. Combating Emerging Firearms Threats. (a) There is hereby established 

an interagency Emerging Firearms Threats Task Force (Task Force). The 

Task Force shall be chaired by the Director of the Office of Gun Violence
