California Gov. Gavin Newsom (D) just signed what many are referring to as the "Glock Ban." 

But, as Breitbart News reports, the move is going to be challenged legally, and it would appear that it is going to be a difficult law for California's legal team to defend.

First, we will look at the ban. Then, we will look at the impending legal challenge.

Newsom has banned the sale of Kamala Harris's gun.

Glocks are the most popular handguns in the country. He banned them anyway.

This bill was first proposed due to a shooting committed by a violent criminal that Newsom's policies released from prison early. https://t.co/x0QkgMCX7f

New sales banned

Newsom signed the bill, known as Assembly Bill 1127, into law last week.

Breitbart explains:

The “Glock Ban” is Democrat-sponsored legislation, fashioned as a response to the use of “Glock Switches,” which are already illegal. “Glock switches” are federally prohibited plastic pieces that can be affixed to the rear of a Glock slide to make the pistol shoot full auto. “Glock switches” are wildly popular with gangs and street criminals, therefore California Democrats are banning new sales of one the most popular handguns ever made, the Glock pistol.

The ban is now set to go into effect on July 1, 2026.

Breitbart goes on to quote some of the text of the bill. It reads:

A “machinegun-convertible pistol” as any semiautomatic pistol with a cruciform trigger bar that can be readily converted by hand or with common household tools into a machinegun by the installation or attachment of a pistol converter, as specified, and “pistol converter” as any device or instrument that, when installed in or attached to the rear of the slide of a semiautomatic pistol, replaces the backplate and interferes with the trigger mechanism and thereby enables the pistol to shoot automatically more than one shot by a single function of the trigger . . . This bill would expand the above definition of ‘machinegun’ to include any machinegun-convertible pistol equipped with a pistol converter and, thus, prohibit the manufacture, sale, possession, or transportation of a machinegun-convertible pistol equipped with a pistol converter.

The new law, if it is going to stay on the books, is going to have to survive a legal challenge.

Newsom's been put on notice

It would appear that a lawsuit against the "Glock Ban" is forthcoming.

Breitbart writes:

The NRA put California Gov. Gavin Newsom (D) on notice that a lawsuit is coming over AB 1127, the bill Newsom signed to enact a ban on new sales of Glock handguns.

The outlet goes on to quote a statement released by the National Rifle Association (NRA).

"Gavin Newsom and his gang of progressive politicians in California are continuing their crusade against constitutional rights," executive director John Commerford said.

He added, "Once again, they are attempting to violate landmark Supreme Court decisions and disarm law-abiding citizens by banning some of the most commonly owned handguns in America. This flagrant violation of rights cannot, and will not, go unchecked."
