- ⚠️ Maryland’s lawsuit against Glock alleges the company enables firearm modifications that turn semi-automatic pistols into illegal machine guns.
- 🔫 A Glock switch can increase a firearm’s firing rate to 1,200 rounds per minute, making it a significant law enforcement threat.
- 🏛️ The lawsuit relies on Maryland’s Gun Industry Accountability Act, aiming to hold manufacturers legally responsible for preventable firearm modifications.
- 📈 Baltimore police have confiscated over 100 illegally modified Glock pistols in the past year, pointing to a growing trend in gun crime.
- 🔍 If the lawsuit succeeds, it may establish a legal precedent impacting future firearms industry regulations and gun control laws.
A new lawsuit filed by Maryland officials against firearm manufacturer Glock highlights growing concerns over gun modifications that enable semi-automatic pistols to function as machine guns. The lawsuit, using Maryland’s Gun Industry Accountability Act, targets Glock for allegedly selling pistols that can be easily modified with a device known as a Glock switch. This controversy underscores critical legal and public safety issues surrounding firearm modifications.

What is a Glock Switch?
A Glock switch, also referred to as an auto sear, is a small but incredibly powerful device that alters a semi-automatic handgun’s firing mechanism, converting it into a fully automatic weapon. Once installed, a Glock switch enables the firearm to discharge an entire magazine with a single trigger pull, allowing it to fire up to 1,200 rounds per minute (Maryland AG Office, 2024).
While legitimate automatic firearms are heavily regulated under U.S. law, Glock switches exploit a legal loophole that allows criminals to create unregulated machine guns. These devices are:
- Small & Concealable – Glock switches are often only about the size of a quarter, making them easy to transport and install.
- Cheap & Accessible – Law enforcement reports suggest illegal Glock switches can be purchased online or manufactured using 3D printing technology.
- Extremely Dangerous – The increase in firepower makes them particularly deadly in criminal activity and standoffs with police.
Because the modification turns handguns into unregulated machine guns, federal law classifies Glock switches as illegal under the National Firearms Act (1934). Possession, manufacture, or distribution of these devices is a felony, yet they continue to surface in violent crimes across the country.
Maryland’s Lawsuit Against Glock
In February 2024, Maryland Attorney General Antony G. Brown and Baltimore Mayor Brandon Scott filed a lawsuit against Glock, Inc., alleging the company’s designs facilitate illegal modifications. The case may become a landmark in firearm industry accountability because it questions whether manufacturers should be responsible for the potential misuse of their products by criminals.
Key Points of the Lawsuit:
- Legal Basis: Filed under Maryland’s Gun Industry Accountability Act (2024), which allows lawsuits against firearm manufacturers for harm caused by their products (Circuit Court of Maryland, 2024).
- Allegation: Glock knowingly designs and sells easily modifiable pistols without taking preventive action.
- Demands: The lawsuit seeks an injunction on sales, financial restitution, and public safety measures to prevent further illegal modifications.
Maryland officials argue that Glock’s failure to modify their designs or limit accessibility to modification devices contributes to firearm violence. If the state wins, the lawsuit could force fundamental changes in how firearm manufacturers approach product liability.

The Role of Glock Firearms in Crime
Maryland officials cite multiple statistical trends to justify legal action against Glock. Data from the Baltimore Police Department suggests that Glock pistols—particularly models easily altered with a Glock switch—are among the most frequently recovered guns in criminal activity.
Notable Findings:
- Glocks are the most commonly seized guns in Baltimore-related crimes (Maryland AG Office, 2024).
- Over 100 illegally modified Glock handguns have been recovered in Baltimore alone in the past year.
- ATF agents consider Glock switches one of the most dangerous firearm threats to law enforcement due to their rapid-fire capability.
These figures underscore a growing trend in firearm-related offenses using Glock pistols enhanced with machine gun conversion devices. Officials argue that tackling this issue at the manufacturer level could prevent widespread firearm modifications before they occur.
Legal Framework: Machine Gun Regulations in the U.S.
For nearly a century, the U.S. has enforced strict regulations against the manufacture, sale, and civilian ownership of machine guns. The introduction of Glock switches presents a direct challenge to these laws:
- National Firearms Act (1934) – Established licensing, registration, and taxation for automatic weapons.
- Gun Control Act (1968) – Expanded restrictions on firearm manufacturing and possession.
- Firearms Owners’ Protection Act (1986) – Banned new machine gun production for civilian use.
Additionally, Maryland law prohibits any firearm capable of fully automatic fire without specific federal authorization. The lawsuit against Glock claims the company enables manufacturers, third parties, and criminals to bypass these restrictions, creating an illegal machine gun market.

Arguments For and Against Glock’s Liability
Arguments Supporting the Lawsuit
- 🏛️ Glock is allegedly aware that its guns can be modified, yet does nothing to prevent it.
- 🚨 Gun violence is worsened by corporate negligence, making firearm manufacturers partially responsible.
- 📉 Glock could redesign its products to prevent illegal modifications but has declined to do so.
- 🔬 Engineering solutions exist, such as internal safeties or redesigned firing mechanisms, but Glock chooses not to implement them.
Maryland officials argue that companies profiting from firearm sales must also take responsibility for predictable misuse and unintended consequences of their designs.
Counterarguments from Gun Rights Advocates & Glock
- 🏹 Firearm manufacturers should not be blamed for how criminals illegally alter their products.
- ✋ Holding gun companies responsible for third-party modifications could set a dangerous legal precedent.
- 🔧 No legitimate customer is intended to use a Glock switch, so redesigning all models is unreasonable.
- ⚠️ This lawsuit could lead to firearm bans or stricter regulations beyond actual problem areas.
Gun rights organizations argue that Maryland’s lawsuit shifts blame away from criminals and onto manufacturers, an approach they say disregards individual criminal responsibility.

Potential Impact of the Lawsuit
If Maryland succeeds, the ruling could reshape how gun manufacturers are held accountable for firearm misuse.
Possible Consequences:
- 🔨 Manufacturers may be forced to alter firearm designs to prevent illegal modifications.
- ⚖️ States could begin holding firearm makers liable for crimes involving their weapons.
- 🔄 New federal legislation could emerge targeting aftermarket gun modifications.
- 🚨 Gun owners could see more restrictions placed on semi-automatic firearms.
Gun rights groups worry this case will expand manufacturer liability laws, potentially opening the door for lawsuits against other firearm companies over unrelated gun crimes. Meanwhile, officials in other states may use this case as a model for their own legal actions against gun makers.
The Maryland lawsuit against Glock is a pivotal case in the ongoing firearms debate. While officials argue that manufacturers should take proactive steps to prevent illegal modifications, gun rights advocates warn this case could set a precedent exposing firearm companies to unlimited liability. Whether Maryland succeeds or not, this legal battle could shape gun industry regulations, firearm safety technology, and Second Amendment rights for years to come.
