A Glock switch or Glock auto-sear (sometimes called a button or a giggle switch) [1][2][3] is a small device that can be attached to the rear of the slide of a Glock handgun, converting the semi-automatic pistol into a machine pistol capable of fully automatic fire. As a type of auto sear, it functions by applying force to the trigger bar to prevent it from limiting fire to one round of ammunition per trigger pull. This device by itself, regardless if it is installed on a slide or not, is considered by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) to be a machine gun, making possession of the device illegal in the United States under most circumstances.
A Glock switch[4] functions by applying force to a semi-automatic pistol's trigger bar to prevent it from limiting fire to one round of ammunition per trigger pull.[5] Normally, in a semiautomatic pistol, after firing the trigger bar catches the firing pin until the trigger is released, but when depressed by the switch it does not catch.A Glock switch thus converts the weapon into a machine pistol capable of automatic fire.[6] The device is roughly the size of a United States quarter, and when installed on the rear of the slide on a Glock pistol (replacing the slide cover plate), adds a selective fire switch; flipping the switch sets the weapon to full automatic mode, which is capable of firing at up to 1,200 rounds per minute.[6]

A handgun with a Glock switch attached fits the definition of a machine gun under United States federal law.[7] The 1986 Firearm Owners Protection Act made new machine guns illegal for civilians to own, banning "possession and transfer of new automatic firearms and parts that fire bullets without stopping once the trigger is depressed", with the exception of machine guns manufactured prior to May 19, 1986.[8] Those caught with a switch-modified handgun can be prosecuted federally.[9] The penalties for possession of an unregistered machine gun in the United States are up to a $250,000 fine and prison sentences of up to 10 years.[8]
In 2019, the ATF recovered thousands of the devices which were imported from China.[10] In 2021 and 2022, people have been manufacturing the switch devices with 3D printers.[7][10] In March 2022, a Vice News investigation learned that the federal prosecutions which involved conversion devices have been rising since 2017. They determined that from 2017 to 2022, advances in low-cost 3D printers and global commerce on the internet have made the devices available for as little as $20 US.[11] In 2022, federal authorities documented a dramatic rise in the prevalence of the Glock switches.[12]
Glock switches have surged in popularity among Columbus criminals and police report they're finding them more and more. The devices can transform a semi-automatic handgun into a fully-automatic weapon, which is an illegal modification.
Lt. Shane Foley of Indianapolis police said machine gun conversion devices are often 3D printed and then sold on the street. In August 2022, a Franklin man was federally charged with manufacturing machine guns after investigators said he was 3D printing firearms and Glock switches that he sold to an undercover agent. Switches also are shipped from overseas, Foley said. ATF filed a case earlier this year against a Dallas man who received 30 switches from Taiwan. Investigators intercepted the packages and an undercover agent made the delivery.
According to the complaint, an undercover ATF agent went on to purchase a total of 33 conversion devices and a 3D-printed AR-15 style pistol from Mr. Watson, who bragged that he could produce roughly 400 switches a day on two 3D printers set up in his living room. He used a tablet to load conversion device printing directions onto the printer.
Buyers must pay a special tax and pass a rigorous background check, Yeates said. The law restricts purchases and firearm transfers to weapons made before 1986, when federal laws prohibited widespread ownership of auto-fire weapons. And federal laws also allow gun store owners or federal firearms licensees who obtain special permission to purchase or manufacture machine guns or auto sears/switches.
But the proliferation in Glock switches now is due to a flood of the devices into the U.S. market from China, either smuggled into the country directly, or through Mexico, said Fred Milanowski, special agent-in-charge of the Houston Field Division of the Bureau of Alcohol, Tobacco, Firearms and Explosives. Agents have also seen a rise in 3D-printed switches, but those tend to be less durable than those manufactured more traditionally.
The charges against Jenkins stem from two incidents in 2022. On October 30th, 2022, records allege that Jenkins, a convicted felon, possessed a Glock model 23, .40 caliber pistol with an affixed machinegun conversion device, known as a glock switch.
The firearm used was a Glock 19 handgun that had been converted to an illegal high-capacity machine gun with a device known as an auto sear, a square device about the size of a thumbnail. It's known on the street as a "switch" that turns the gun from a semi-automatic to an automatic weapon.
The Glock came with an extended magazine, making the weapon even deadlier. The magazine held 34 rounds, according to court records. Sanders told authorities he bought the gun in Indiana and the switch for less than $25.
Similarly, the proliferation of switches is a nationwide issue. The number of switches recovered by the Bureau of Alcohol, Tobacco, Firearms and Explosives rose from 100 in 2017 to about 1,500 last year, according to Whitney Cruse, a special agent and spokesperson for the ATF's Washington Field Division.
Virtually every handgun available to the public at licensed gun stores is semi-automatic, meaning the shooter needs to squeeze the trigger every time a shot is fired. When a semi-automatic handgun is turned into an automatic with a switch, the bullets will continue to fire as long as the trigger is squeezed and held. With an extended magazine, shooters can unload 20 rounds from a modified Glock in about a second, according to James Barlow, a firearms enforcement officer with the ATF.
Many of the switches seized with handguns in Chicago were made in China, according to federal officials. They're marketed online for other purposes, such as attachments for replica "airsoft" guns that fire plastic projectiles. Those switches are metal. The ones made with 3D printers, often in homes, are less durable plastic. The instructions for attaching the switches to a handgun are easily available online.
In Chicago, police officers began seeing switch-equipped handguns hit the streets in 2018. Around that time, they were also seeing an uptick in mass shootings, many occurring with the use of high-capacity magazines.
Law enforcement officials in Chicago said they've stepped up efforts to combat the sudden popularity of makeshift machine guns. In federal court, cases involving switches are resulting in stiff prison sentences for some convicted dealers.
Last August, Leonard Johnson, who was left paraplegic as a result of a 2008 shooting, was sentenced to 10 years in prison after being convicted on charges of supplying four Glock switches to someone who sold them to an undercover officer and an informant.
In December 2020, federal authorities searched Johnson's home in a Chicago suburb and found 117 switches and three handguns converted into machine guns. They also seized another handgun, a silencer, three extended magazines and ammunition. While he was out on bail, he continued to traffic firearms and Glock switches, prosecutors said.
"The sole and exclusive purpose of Glock switches, which are easily manufactured, is to convert an already dangerous firearm into an extremely dangerous machine gun," U.S. District Judge Iain Johnston said in his written sentencing order. "The dangerousness manifests itself not only in the sheer number of bullets that can be emptied from the magazine in the blink of an eye but also in the resulting lack of control of the firearm when discharging it."
As federal authorities try to address the growing, nationwide switch problem, the emergence of widely available technology that allows traffickers to produce the switches using 3D printers has made it even harder.
"We're kind of in a transition period," said Barlow, who oversees an ATF unit that trains new firearms enforcement officers. "It used to be we would see a lot of the imported-style switches [from China], but the 3D printing stuff actually is becoming more prevalent. We're probably close to a 50-50 mix between the two right now."
New types of switches are hitting the underground market, too. The "invisi-switch" looks nearly identical to the slide that covers the barrel of a legal, semi-automatic Glock, Barlow said. Traditional switches, on the other hand, are easier to spot: The thimble-size devices stick out of the back of a handgun.
In 2019, when switches started gaining popularity in Chicago, ATF began working with Homeland Security Investigations, U.S. Customs and Border Protection, and the U.S. Postal Inspection Service on two global task forces targeting switches. One of their investigations, dubbed Operation Silent Night, also goes after extended magazines and gun silencers or suppressors.
The switches made in China are sometimes sold online as kitchen utensils, carburetor parts or components for pellet guns, Barlow said. Once they get to the United States, they're sold within criminal networks in a similar fashion to the illegal drug trade.
Sean Fitzgerald, acting special-agent-in-charge of the Homeland Security Investigations' Chicago office, said his agency has identified "multiple regions" in China where switches are manufactured. In many cases, the manufacturers quickly dissolve after coming under scrutiny, only to be replaced by others, he said.
Fitzgerald said his agency has been working with Chinese counter-smuggling officials in an effort to target those operations and advance some of the roughly 650 investigations that Homeland Security has launched into switches, extended magazines and silencers.
