Maryland’s “Glock Ban” Isn’t the Same as California’s. Here’s the Difference

If you've been following the news surrounding Glock pistols lately, you've probably heard about new restrictions in both California and Maryland. That has led to a lot of shorthand about states “banning Glocks.” But the laws aren't identical, and for Maryland gun owners, that's an important distinction.

California made headlines first. Maryland followed with its own law, which takes effect for these transactions on January 1, 2027. And in one important respect, Maryland's law reaches beyond simply telling firearm dealers what they can and cannot sell.

Here's what Maryland gun owners need to know.

Neither State Literally Banned Every Glock by Name

First, it's worth clearing up what these laws actually do. Neither law simply says, “Glock pistols are banned.”

Instead, both states created a legal category based on the design of certain semiautomatic pistols and whether they can be converted to fully automatic fire using a conversion device commonly called a “Glock switch.”

Maryland's law calls these firearms “machine gun convertible pistols.” It defines that category around specific design characteristics, including a cruciform trigger bar and the ability to install a pistol converter in place of the slide's backplate without additional engineering, machining or modification of the trigger mechanism.

That design is closely associated with Glock pistols, which is why you've heard this described as the “Glock ban.” But the law isn't actually based on the Glock name stamped on the slide. It could affect other pistols that meet Maryland's definition as well.

So What Did California Do?

California's AB 1127 created a similar category of “machinegun-convertible pistols.” Beginning July 1, 2026, California law prohibits licensed firearm dealers from selling, offering for sale, exchanging, giving, transferring or delivering pistols meeting that definition, with certain exceptions.

There's another piece of the California situation that's important: California already had its Handgun Roster. That system has long determined which handgun models dealers can sell to the general public in California. The new law operates alongside that existing system and includes provisions allowing manufacturers to redesign affected pistols and submit compliant versions for testing.

That's part of why the Glock situation in California can look different from what we're facing here in Maryland.

Maryland Goes Further in One Important Way

This is where Maryland gun owners really need to pay attention. Beginning January 1, 2027, Maryland prohibits a person from: manufacturing, selling, offering for sale, purchasing, receiving, or transferring a pistol that meets the state's definition of a “machine gun convertible pistol,” unless one of the law's specific exceptions applies.

That distinction matters. Maryland isn't simply telling firearm dealers like The Machine Gun Nest that we won't be able to sell certain pistols after January 1.

The law also says that a person generally cannot purchase or receive one of those prohibited pistols after the deadline. In other words, this affects both sides of the counter.

For Maryland gun owners considering one of the affected pistols, January 1 isn't simply a date when gun stores have to remove something from their inventory. It represents a change in what Maryland residents themselves can legally acquire.

What Happens to a Glock You Already Own?

Here's another place where the word “ban” can create unnecessary confusion. Maryland's law does not say that everyone who already owns an affected Glock suddenly has to surrender it on January 1, 2027. The new prohibition focuses on manufacturing, selling, offering for sale, purchasing, receiving and transferring these firearms after the deadline.

The law also contains specific exceptions, including certain circumstances involving immediate family members, inheritance and firearms being transferred temporarily to licensed dealers or gunsmiths for servicing.

So ownership before the deadline and acquiring one after the deadline are two very different issues.

If you already legally own an affected pistol, January 1 does not automatically make possession of that firearm illegal under this new provision.

What About the Actual Glock Models?

This is one area where we're still waiting for additional clarity. The law requires Maryland State Police to adopt regulations implementing it and to publish a list of the “machine gun convertible pistols” prohibited under the new law.

That's going to be an important list.

We've previously discussed the Glock models and other pistols that appear likely to fall within the law based on its technical definition. But until Maryland State Police publishes its official list, we're not going to pretend that an unofficial list is the final word. As soon as the State publishes more information, we'll break it down for our customers.

Why This Matters Before Glocktober

There's been plenty of discussion online about what's happening to Glock in California. But if you're a Maryland gun owner, don't assume California's rules tell you what's going to happen here. They don't. Maryland passed its own law. It has its own definitions, its own exceptions and its own deadline.

And for Maryland gun owners, the most important date is: January 1, 2027.

After that date, Maryland's new restrictions on purchasing and receiving covered pistols begin. That's why we'll be spending some extra time talking about Glock over the next few months.

Glocktober has always been a fun excuse to talk about one of the most recognizable handgun platforms in the world. This year, there's obviously more to the conversation. We'll be breaking down the law, looking at different Glock models, helping customers understand the differences between them and keeping you updated as Maryland State Police releases more information.

If there's a Glock you've been considering, now is the time to start doing your homework, not on December 31. Come in, ask questions, rent different models and figure out what actually works for you. We'll help you understand your options while they're still options.
