Assembly Bill 1127 (AB 1127), introduced by Assemblymember Jesse Gabriel, is being referred to by critics as California’s “Glock ban.” The bill aims to prohibit the sale of certain semiautomatic pistols that can be readily converted into fully automatic firearms using illegal aftermarket devices, such as Glock switches. While the goal is to reduce gun violence, the proposal misses the mark both legally and practically.
Current Status of AB 1127
As of May 29, 2025, AB 1127 has cleared all assigned committees and is awaiting a vote on the Assembly floor. If passed, it will move to the State Senate for further deliberation. Notably, the bill was previously placed on the Assembly Appropriations Committee’s suspense file (a holding area for bills with significant financial implications) but has since advanced.
Key Provisions in the Bill
- Targeted Firearms: The bill prohibits the sale of semiautomatic pistols that can be “readily converted” into machine guns with devices like Glock switches.
- Exemptions: Current owners may retain their firearms. Law enforcement and military agencies are also exempt.
- Dealer Inventory: Licensed firearm dealers may sell existing stock purchased prior to the law’s effective date, allowing for a transition period.
Federal Law Already Covers This
What the bill’s sponsors seem to overlook is that federal law already prohibits converting semiautomatic firearms into fully automatic weapons. Under:
- 18 U.S. Code § 922(o), part of the Gun Control Act of 1968, amended by the Firearm Owners’ Protection Act of 1986, the possession or transfer of newly manufactured machine guns is banned for civilians.
Violating this law is a federal felony, punishable by up to 10 years in prison and a $250,000 fine.
Data and Perspective
According to the ATF, there were 5,816 Glock switches and similar conversion devices recovered nationwide in 2023. California holds roughly 12% of the U.S. population, meaning it could account for about 700 devices or roughly 1.75 per 100,000 residents.
To put this in perspective:
- California sees more fatal car crashes per capita than it sees Glock switches.
- According to the Insurance Institute for Highway Safety (IIHS), California had 11.3 traffic deaths per 100,000 residents in 2022.
Yet there’s no call to ban cars.
The Real Impact of AB 1127
Criminals don’t follow gun laws. They’ll continue to use handguns with standard-capacity magazines, threaded barrels, and yes, sometimes even illegal switches. This bill doesn’t make California safer, it targets law-abiding gun owners.
And here’s the irony: California’s Roster of Certified Handguns is supposed to ensure that only “safe” handguns are available to the public. If these Glock-style pistols are already on the roster, then how can they now be labeled unsafe? And if they are so dangerous, why are law enforcement agencies exempt?
Likely Scenarios
Here are three likely outcomes for AB 1127:
- It dies in the Senate: Once fiscal costs are reviewed, lawmakers may realize the state can’t afford the added enforcement burden.
- It gets vetoed by Governor Newsom: If Newsom has presidential aspirations, killing this bill could be used to show moderates he’s not blindly anti-gun.
- It becomes law: Lawsuits will follow. A likely injunction leads to a drawn-out legal battle. Meanwhile, taxpayers foot the bill for both enforcement and litigation.
Final Thoughts
AB 1127 is a solution in search of a problem, pushed by lawmakers who either don’t understand federal law or are more interested in headlines than real safety. It’s another example of punishing legal gun owners while doing little to stop criminals. As with many California gun laws, the cost isn’t just to liberty; it’s to the taxpayers who will fund the legal fight.
