Are glock Switches Legal? The Definitive Answer for 2026

On January 23, 2025, the ATF published Final Rule 2024R-09, redefining “machinegun” to include any device “designed, made, and intended” to convert a semi-automatic into a machinegun, regardless of functionality. This directly targets forced reset triggers and specific auto-sear designs. If you own a glock, understanding this new legal landscape is not optional—it’s critical for staying compliant and protecting your rights.

The National Firearms Act (NFA) and Machine Gun Definition

The core legal framework is the National Firearms Act of 1934, amended by the Firearm Owners’ Protection Act of 1986. Under the NFA, a “machinegun” is defined as any weapon which shoots, is designed to shoot, or can be readily restored to shoot, automatically more than one shot, without manual reloading, by a single function of the trigger. This includes the receiver of such a weapon and any combination of parts designed and intended for use in converting a weapon into a machinegun. That last part is the key. A glock switch, also known as an auto-sear or selector switch, is considered one of those “combination of parts.” Since May 19, 1986, it has been illegal for civilians to manufacture or register new machine guns for personal ownership. Possessing an unregistered glock switch is possession of an unregistered NFA item, a federal felony.

State Laws vs. Federal Law: Where You Live Matters

Federal law sets the baseline, but state laws can be far more restrictive. Even if you navigated federal NFA registration (which for new-manufacture switches is impossible), your state might outright ban possession. For example, California Penal Code § 32625 prohibits possession of any “multiburst trigger activator,” with no exceptions for NFA registration. New York, New Jersey, Illinois, and Washington state have similar blanket bans. In contrast, states like Texas, Florida, and Arizona do not have additional state-level prohibitions beyond federal NFA rules, but the federal ban still applies in full force. You must consult your state’s specific statutes. At Glockswitchkit, we enforce strict geographic sales restrictions to prevent shipments to prohibited jurisdictions, but ultimate compliance responsibility rests with the owner.

Legal Consequences of Illegal Possession

The penalties are severe and non-negotiable. Under 26 U.S.C. § 5861, possession of an unregistered machine gun (which an unregistered switch constitutes) is punishable by up to 10 years in federal prison, a fine up to $250,000, and forfeiture of all firearms involved. That’s per violation. Prosecutors often stack charges. Furthermore, under the 2025 ATF rule, even possessing certain components with the intent to create a machinegun can lead to prosecution. Your firearm will be confiscated, and you will face a permanent felony record, losing your right to own any firearm ever again. This isn’t theoretical; arrests for possession of glock switches, particularly those purchased from overseas or through illicit channels, have skyrocketed in recent years.

Legal Alternatives: Enhancing Your glock Within the Law

You cannot legally convert your glock into a full-auto machinegun. However, you can significantly improve its performance with 100% legal aftermarket parts. Focus on triggers that provide a clean, crisp break and reduced travel without violating the “single function of the trigger” rule. For a duty-ready upgrade, the Johnny Glock Combat Trigger system is unmatched. For competition, look at the Zev Technologies Pro Flat Face kit. Beyond triggers, consider our store’s selection of precision barrels from KKM or Agency Arms, robust slide stops, and enhanced magazine releases. These modifications, when installed correctly, offer tangible benefits for defense or sport shooting without crossing the legal line into NFA territory.

How to Stay Informed and Compliant

Laws change, and ATF interpretations shift, as seen with the 2025 ruling. Your first resource should always be the actual text of federal law (26 U.S.C. Chapter 53) and your state’s penal code. For ongoing updates, follow legal analyses from established Second Amendment advocacy organizations like the Firearms Policy Coalition (FPC) and the Second Amendment Foundation (SAF). Do not rely on social media rumors or forum speculation for legal advice. When purchasing any aftermarket part, especially those related to the fire control group, buy from reputable, U.S.-based dealers like Glockswitchkit who understand and adhere to the law. We provide product descriptions that clearly state intended use and compliance status.

Can I own a glock switch if I have an FFL/SOT license?

Yes, but only with the proper Federal Firearms License (FFL) paired with a Special Occupational Tax (SOT) Class 2 or Class 3 status. This is for manufacturers, dealers, and entities like police departments. The device must be registered on an ATF Form 2 or Form 3, and strict record-keeping is required. Personal possession by an SOT holder outside of business purposes is generally not permitted.

What about “forced reset triggers” (FRTs)? Are they legal?

As of the ATF’s Final Rule 2024R-09, most forced reset trigger designs are explicitly classified as machineguns. The ATF’s position is that the “automatic” function occurs during the trigger’s forward reset, not the rearward pull. Unless a specific FRT model has a favorable court injunction against the ATF (which is rare and temporary), possession is considered illegal. Do not purchase or install an FRT without direct, current legal counsel.

I bought a switch online from another country. Is it legal now?

No. Importing a machine gun part without proper ATF authorization is a separate federal crime. Even if it arrives, possession is still illegal under the NFA. Customs and Border Protection (CBP) actively intercepts these shipments, and receiving one can trigger a visit from the ATF. Purchasing from overseas is one of the highest-risk actions you can take.

The only safe path for a civilian shooter is to pursue high-quality, legal performance upgrades.
