Glock Ban Bill Moving Through State Senate

California lawmakers are moving forward with a gun violence bill that seeks to ban the sale of specific semi-automatic pistols considered as “machinegun-convertible pistols” due to their design, which proponents argue makes them easily modifiable into fully automatic weapons. The legislation, often referred to as the “Glock ban,” has drawn attention over Second Amendment rights.

Assembly Bill 1127 will ban the sale of semi-automatic pistols that can be converted into machine guns using devices called “pistol converters” or “Glock switches.” While these conversion devices are already illegal, the bill targets the firearms themselves.

It defines a “machinegun-convertible pistol” as any semi-automatic pistol with a cruciform trigger bar that can be converted into a machine gun by simply replacing the slide’s backplate with a pistol converter. This legislation mainly affects Glock and similar pistols, which feature this trigger design. The bill clarifies that a “pistol converter” is a device that, when attached, allows the pistol to fire automatically with one trigger pull.

Pistols not included in this definition are hammer-fired semi-automatic pistols or striker-fired semi-automatic pistols that lack a cruciform trigger bar and instead have a trigger bar shielded from interference by a pistol converter. The bill also explicitly states that a polymer notch or other molded piece at the rear of the pistol frame does not prevent it from qualifying as “machinegun-convertible.”

The bill would prohibit licensed firearms dealers from selling “semi-automatic machinegun-convertible pistols” starting January 1, 2026. Existing pistols delivered before this date, sales to law enforcement and the military, and certain private transfers would be exempt. Current owners wouldn’t have to surrender their firearms, but new sales would be limited.

Violations by dealers would incur a three-strike penalty: a first offense results in a fine up to $1,000, a second offense up to $5,000 with possible license suspension, and a third offense as a misdemeanor resulting in license revocation.

“DIY Machine Guns”

Assemblymember Jesse Gabriel argues that the legislation is a “commonsense solution” to prevent gun violence. He highlights that some semi-automatic firearms can be easily converted into fully automatic weapons using inexpensive “switches” that can be 3D-printed and installed quickly with common tools.

Advocacy groups like Moms Demand Action and Everytown for Gun Safety emphasize that “no one needs a pistol that can be turned into a machine gun.” They say that these devices are increasingly accessible and deadly. Proponents seek to hold manufacturers accountable by requiring design modifications for continued sales in California.

In a fact sheet released by Moms Demand Action, statistics are cited regarding violent incidents involving pistol switches and the increased use of these modified weapons. The ATF reported a 570% increase in machine gun conversion devices from 2017 to 2021. These modified pistols can fire up to 1,200 rounds per minute.

In 2022, a Sacramento shooting involving a DIY Glock machine gun resulted in six deaths and twelve injuries. In 2019, a converted Glock killed four and injured six in Fresno.

Constitutional Concerns

Opponents of AB 1127, including Gun Owners of California (GOC) and the California Rifle and Pistol Association (CRPA), argue the bill is an unconstitutional “gun grab” that punishes law-abiding citizens and does little to deter criminals. They contend the bill unfairly targets legally owned firearms based on the potential for illegal modification.

Critics like Sam Paredes, Executive Director of GOC, point out that devices like “Glock switches” are already illegal, making the bill redundant.

The comparison to “bump stocks” is frequently drawn. While bump stocks, which increase the rate of fire, were also outlawed, this bill goes further by banning the semi-automatic firearms themselves, not just the illegal modification devices. Critics argue that banning guns that could be illegally modified is akin to banning cars because someone might illegally install nitrous oxide.

Gun rights advocates cite Supreme Court rulings in Heller v. District of Columbia (2008) and McDonald v. City of Chicago (2010) that affirm an individual’s right to possess firearms for self-defense. The 2022 Bruen decision further requires the government to prove that new gun laws have historical precedents related to the Second Amendment.

Critics also highlight that Glock’s Gen 4 and Gen 5 models have been modified to meet concerns but can’t be added to the state’s firearm roster, suggesting state hypocrisy in blocking safer handgun access while blaming legal gun owners. They argue the bill won’t effectively combat crime as criminals already disregard firearm laws.

Broader Implications

Successful measures can influence other blue states, such as California, which was the first state in the nation to ban assault weapons in 1989. Illinois Democrats have introduced bills (HB 4045 and its Senate companion) to ban the sale of “convertible pistols,” making such acts a felony.

Similarly, Maryland is pursuing HB 1287 to prohibit the sale of semi-automatic pistols that can be easily converted into machine guns. Chicago and Baltimore have filed lawsuits against Glock, claiming its pistols can be modified into machine guns and contribute to gun violence.
