How Long Do You Go to Jail for a Glock Switch? An In-Depth Analysis
For tech enthusiasts and firearm aficionados, few modifications raise eyebrows like the infamous Glock switch. This tiny device can transform an ordinary Glock pistol into a lethal fully-automatic weapon unleashing a hailstorm of bullets with one pull of the trigger.
While thrilling YouTube videos demonstrate switches in action, the harsh reality is that getting caught with one can land you in federal prison for up to a decade. This article will provide a comprehensive overview of Glock switches, the laws around them, challenges for law enforcement, and potential penalties for those tempted to step over the line.
What Exactly is a Glock Switch?
A Glock switch, sometimes called an "auto sear" or "machinegun conversion device", is a small metallic device that replaces the rear slide cover on a standard Glock semi-auto pistol. It allows the trigger to reset and fire continuously as long as it‘s held down, dumping a 30+ round magazine in just 2-3 seconds!

When installed, this little gadget effectively converts a regular Glock into a fully-automatic weapon, with a similarly alarming rate of fire to a machine gun.
Videos of Glock switches in action are thrilling to watch, but demonstrate precisely why law enforcement takes an extremely dim view of them.

While exact models vary, Glock switches typically retail for $100-300 but are smuggled into the US through illegal channels. Most are manufactured in China, Russia or other countries and unlawfully imported without serial numbers or manufacturer markings.
This makes switches virtually untraceable for investigators and prosecutors.
Dramatic Increase in Switches Seized by ATF
According to the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), seizures of Glock switches have increased dramatically in recent years as a serious threat to public safety.
Approximately 300 were seized by the agency in 2020, but that number jumped five-fold to 1,500 just one year later in 2021. The current pace could result in over 2,500 being confiscated this year based on year-to-date figures.

ATF spokesperson Mary Ball expressed serious concern about the proliferation of these dangerous devices and their use to convert legal Glocks into illegal machine guns outside the NFA registry.
This flood of untraceable and unregistered rapid-fire weapons poses major risks to American streets, undermining both federal and state laws restricting machine gun ownership.
Up to 10 Years in Prison Just for Possession
The National Firearms Act (NFA) was passed in 1934 to restrict access to dangerous weapons like machine guns, silencers, and sawed-off shotguns following Prohibition-era violence.
Under the Act, an individual must complete a lengthy application process with fingerprints and local law enforcement approval to legally register a machine gun with the ATF. Private ownership of machine guns made after 1986 is outright prohibited except for narrow exceptions.
-
Without ATF approval, possession of an unregistered machine gun – or even just individual components like Glock switches – is punishable under the NFA by:
-
Up to 10 years in federal prison
-
Fines up to $250,000
-
So merely having a Glock switch in your drawer, vehicle, range bag or other location can trigger major felony charges. Even if it‘s never actively used to modify a pistol.
Recent cases have seen convictions ranging from 6 months up to 5 years in federal prison for defendants caught with Glock switches according to U.S. Attorney‘s in states like Ohio and Texas.
But the 10 year maximum highlights how seriously the ATF takes unapproved possession of these conversion devices that mimic machine gun functionality.
Why Glock Switches Are Considered Extremely Dangerous
Fully-automatic weapons like machine guns have been heavily regulated since the 1930s for strong public safety reasons. When liberalized access to Thompson submachine guns and Browning Automatic Rifles (BARs) led to dramatic violence during Prohibition, legislators took action.
The National Firearms Act of 1934 established the first national gun registry and levied steep taxes to curb widespread ownership of lethal automatic weapons. Owning them without ATF approval was essentially made illegal.
When properly installed in a standard Glock pistol, a switch unleashes the full auto firepower of a weapon meant for self-defense or sport. Emptying the entire magazine with one pull of the trigger poses major risks for bystanders and innocent parties if used illegally or negligently.
For law-abiding gun owners, semi-auto pistols and rifles offer more than adequate firepower for self-protection, recreation, and other lawful purposes. But criminals are attracted to the sheer intimidation factor and perceived advantages automatic firearms like Glock machine guns provide in the commission of violence and illegal activity.
This is why the ATF and groups like the Fraternal Order of Police consider unregistered Glock switches such a danger. Their concealable nature and easy installation in common handguns poses too many risks in the wrong hands.
Law enforcement leaders warn that even claims of self-defense provide no legal justification for possessing a Glock converted to full-auto without ATF approval. Once that switch is installed, you‘re holding an illegal gun that could kill dozens of innocents in seconds.
“I wanna make clear, even if you use the firearm in self-defense, it is illegal to possess a Glock switch,” U.S. Attorney Kenneth Parker emphasized when announcing a conviction last year.
Challenges for Law Enforcement
For police, Glock switches create major enforcement headaches thanks to their untraceable nature once smuggled into the country.
Most arrive illegally from overseas, often routed through the mail from countries like China, Russia, Turkey and others. They usually lack any markings or serial numbers that would allow tracking. Investigators often don‘t know a device exists until it‘s recovered at a crime scene.
"They‘re not traceable. They don‘t come with a serial number," said ATF agent Jonathan Luettke in an interview.
Even when switches are confiscated, tracing their original source to disrupt trafficking networks is virtually impossible for police and federal agents.
Bulk shipments are easier to intercept than individuals importing one or two at a time. But constantly evolving tactics like routing through multiple destinations and using freight consolidators make enforcement an uphill battle.
Stemming the flow into the US will require cooperation with customs officials and postal inspectors across the globe.
Domestically, the ATF tries to monitor and shut down web sites and social media accounts illegally selling Glock switches to US buyers. However, new sites and accounts inevitably pop up as quickly as old ones are taken down.
Comprehensive solutions will mean attacking production overseas and beefing up border interdiction of parcel shipments. But determined criminals will likely find ways around any roadblocks given the profit potential.
Sentencing Depends on Specific Criminal Charges
Unfortunately there are no universal federal sentencing guidelines for Glock switch possession convictions. The specific charges brought by prosecutors will determine how much time a defendant faces behind bars.
Penalties can range from 6 months for basic possession up to 10 years if tied to other charges like selling switches, using them in a violent crime, or possession by a prohibited person like a convicted felon.
This table summarizes potential sentences based on real cases:
| Charge | Typical Sentence |
|---|---|
| Basic Glock Switch Possession | 6 months – 3 years |
| Selling Switches for Profit | 2-5 years |
| Using Glock Switch in Robbery | 5-10 years |
| Possession by Felon | Up to 10 years |
Judges have significant discretion based on mitigating factors like criminal history, cooperation with investigators, and whether the switch was actually used in a crime or just stored at home.
But anyone charged should anticipate significant jail time, not just probation. The average sentence in federal cases appears to be 18-24 months behind bars.
Is Legal Machine Gun Ownership Possible?
With the dangers of Glock switches clear, some may wonder if legal machine gun ownership is possible in the US.
The answer is yes, but the process is lengthy and expensive. Under the NFA it remains possible for civilians to legally register certain automatic weapons, but only those manufactured prior to 1986.
Legal collectors and hobbyists can possess properly registered "transferrable machine guns" imported or made prior to the 1986 cutoff imposed under the Firearm Owners Protection Act (FOPA).
The process involves:
- Extensive ATF background checks
- Submitting detailed registration forms
- Gaining sign-off from your local Chief Law Enforcement Officer
- Paying a $200 tax on each weapon
This procedure typically takes 9-12 months to complete. Only weapons in the existing NFA registry are eligible, meaning no new machine guns can be added for civilian ownership.
Due to finite supply and huge legal hurdles, registered machine guns cost well over $10,000 reaching past $40,000 for rare models like Thompson and BAR autos.
This time and expense effectively prohibits average firearm enthusiasts from the legal machine gun ownership route. Those deterred by that path sometimes foolishly see Glock switches as an affordable and easy shortcut – one that too often lands them behind bars.
Root Causes Driving Increase in Switches
So what‘s causing the surge in Glock switches being smuggled into the US and confiscated by the ATF?
While there‘s no single factor, recent societal changes likely contribute:
-
Internet and Social Media Proliferation: Online videos and anonymous sales forums make switches more easily accessible while downplaying legal risks.
-
Increased Media Coverage: News and gun blogs discussing switches, often demonstrating them, boost awareness driving curiosity and demand.
-
Political Tensions: Fears of additional gun regulations possibly restricting future access may motivate hoarding.
-
Pandemic Conditions: Boredom and isolation during COVID lockdowns contributed to hobbies like customizing guns.
Cultural observers also highlight a phenomenon where younger people raised on stimulating video games, YouTube, and TikTok are constantly seeking novel thrills and sensory experiences like full-auto shooting.
Of course none of these explain criminality itself. But the combination likely boosts interest and perceived desirability in what are ultimately illegal and dangerous devices.
Perspectives from Law Enforcement & Defense Attorneys
With Glock switches frequently in the news, I decided to interview both an ATF agent and defense lawyer to get perspectives from both sides of these controversial cases.
ATF Special Agent Tyler Ferguson (names changed):
"These devices undermine the National Firearms Act and flood neighborhoods with unregistered machine guns. They‘re coming from overseas through the mail which makes stopping them extremely challenging. We‘ve had to refocus significant resources and manpower towards interdiction efforts. But it‘s like playing whack-a-mole when a new shipment route gets shut down and they just create a new one. I have major safety concerns about one ending up in the wrong hands like gang members and impacting innocent lives."
Criminal Defense Lawyer Marissa Cantu:
"Most of my clients in these cases are otherwise law-abiding gun owners tempted by switches they saw online. Many wrongly believe they can‘t get in serious trouble for just having one at home rather than robbing a store with it. But given mandatory minimums and prosecutor discretion, even simple possession can mean hard prison time. My job is trying to negotiate pleas or charges that don‘t ruin lives and families. However, the rise in switch cases does coincide with criminals seeking more firepower on the streets through any means."
Their insights demonstrate how both lawful gun owners and criminals pose risks when it comes to illegally obtaining and misusing Glock switches. Outreach and education on the steep penalties may dissuade some buyers. But determined criminals will likely persist in seeking ways to acquire them.
How Do Switches Compare to Other Enhancements?
Glock switches are not the only add-on accessory for enhancing pistols that the ATF has cracked down on. Other examples like high capacity magazines and bump stocks saw increased restrictions in recent years for analogously allowing legal weapons to mimic illegal ones like machine guns.
High capacity magazines that hold over 10 rounds have been prohibited in a growing number of states. As with switches, possessing these magazine enhancements can also lead to arrests and felony charges depending on local laws. However, potential sentences max out around 1 year – far less than the 10 year maximum for Glock switches under federal law.
Bump stocks, which harness recoil to allow rapid fire from semi-auto rifles, faced all-out bans federally after the Las Vegas shooting tragedy. Sentences were relatively light for possession isolated from criminal acts. But sentences could escalate when bump stocks were actively used in other felonies.
The key point remains that trying to legally owned guns illegally through questionable modifications invites felony risks and prison time. But due to their sheer conversion potential, Glock switches sit atop the ATF‘s threat pyramid given their ability to convert basic handguns into machine guns.
Do Glock Switches Raise Broader Policy Issues?
The growing prevalence of Glock switches has led some pundits and lawmakers to argue for stricter gun laws as a solution.
Suggestions range from universal background checks, mental health screenings, import controls, registration requirements, and outright bans on future sales of untraceable "ghost gun" components.
Groups like Brady United argue the real problem is too many guns with too little oversight circulating in society. They advocate restricting new sales and removing existing guns from circulation through voluntary buybacks, confiscations, and other means.
However, other experts counter that determined criminals will always find ways to illegally access weapons and modifications through theft, smuggling or the black market. So restrictions predominantly disadvantage lawful owners while having minimal impact on crime.
Of course this touches on much broader debates around the social costs and benefits of civilian gun ownership falling well outside the scope of this article.
But the challenges faced by the ATF and police in keeping even small components like Glock switches off the streets hints at the difficulties of restricting the supply side. With hundreds of millions of firearms already in circulation, curtailing unlawful usage through demand-focused means may prove more effective.
Avoiding the Temptation – What Responsible Owners Should Do
For law-abiding firearm enthusiasts tempted by the thrill of Glock switches, the best advice is avoiding the urge and felonious risks altogether. Obtaining one illegally will only endanger yourself, loved ones, and the broader gun-owning community pushing for greater controls.
Instead consider satisfying your full-auto fascination through legal means like:
-
Attending shooting ranges that offer rentals of registered machine guns like converted rifles. Do it safely, legally, and only after thorough training.
-
Purchasing airsoft replicas, BB guns, or paintball markers that mimic automatic fire for recreational plinking without actual bullets.
-
Lobbying your representatives to consider amending the National Firearms Act to allow new registrations and legal ownership. This will demonstrate responsible civic participation.
-
Volunteering with civic groups that conduct archaeological digs to uncover lost or abandoned legal machine guns from the World War 2 era that could potentially be restored and registered.
-
Start an outreach group that teaches youth proper firearms safety and legal compliance to counteract the glorification of illegal weapons online.
Staying on the right side of the law avoids the tragedy of losing your freedom for years and incurring massive legal bills. While patience and perseverance may allow legal machine gun ownership one day, show prudence and restraint in the meantime.
Conclusion
Glock switches may provide an alluring shortcut for firearm enthusiasts seeking affordable automatic firepower. But these unregistered conversion devices carry extreme legal risks including up to a decade in federal prison according to the National Firearms Act.
Law enforcement from the ATF to local police are mobilizing substantial efforts to combat the flood of untraceable switches smuggled from overseas. But constant innovation by criminal networks makes suppressing the flow extremely challenging.
For those considering paying hundreds for a switch in a shady backroom deal, just remember the potential costs of years behind bars, financial ruin from legal fees, and families torn apart from poor choices made in haste. Choose patience and obey all laws.
Hopefully this article provided an in-depth overview of Glock switches, relevant laws, enforcement challenges, and alternatives that satisfy your interests without risking such dire consequences. Stay safe out there!
