Maryland Is Banning Your Glock — And They're Calling It a Machine Gun
SB 334 would ban the sale of most Glock pistols in Maryland. Not because of what you did — but because of what a criminal could do to it.
Bans "Machine Gun Convertible Pistols"
After January 1, 2027, no person may manufacture, sell, purchase, receive, or transfer any pistol Maryland classifies as "machine gun convertible." Here's what that actually covers.
Targets the Cruciform Trigger Bar
Any semiautomatic pistol with a cruciform trigger bar that can be "readily converted" using common household tools is banned. This is a core Glock design feature — it's how every standard Glock operates.
Bans Sale, Not Just Modification
You don't have to modify the gun. You don't have to own a switch. The gun is banned because the design could theoretically accept one. The capability is the crime.
3D-Printed Converters Included
The bill explicitly includes converters manufactured using 3D printers in the definition of "pistol converter" — expanding the scope beyond machined metal parts.
State Police Get an Expanding List
Maryland State Police can adopt regulations and publish a growing list of prohibited pistols. Your specific model may not be named today, but it could be added at any time.
What IS a Cruciform Trigger Bar?
SB 334 targets a single internal part that most gun owners have never even seen. Here's what it is, where it sits, and why Maryland is using it to ban your pistol.
It's a Standard Internal Part
The cruciform trigger bar is a small metal component that sits inside the frame of every standard Glock pistol. It gets its name from its cross-shaped (cruciform) profile — two arms extend outward from a central bar.
Its job is simple: when you pull the trigger, the cruciform bar moves rearward to release the firing pin (striker), allowing the gun to fire one round per trigger pull. It is the core of Glock's "Safe Action" trigger system — a design praised for reliability across military, law enforcement, and civilian use worldwide.
- 1 Cruciform trigger bar — the cross-shaped internal part SB 334 targets. Present in every standard Glock.
- 2 Slide backplate — the rear cover criminals replace with an illegal auto-sear ("switch").
- 3 Frame / receiver — the serialized lower housing. The cruciform bar sits inside this.
Key point: The cruciform trigger bar is not an accessory. It's not aftermarket. It cannot be removed without disabling the firearm. SB 334 defines any pistol containing this part as a "machine gun convertible pistol" — even though the part itself has nothing to do with automatic fire.
Pull Trigger → 1 Round Fires
The cruciform bar moves rearward, releasing the striker. You must release and re-pull the trigger for the next shot. This is standard semiautomatic function.
Install a "Switch" on Backplate
An illegal auto-sear replaces the slide backplate and overrides the trigger mechanism to enable full-auto fire. This is already a federal felony under the NFA — up to 10 years in prison.
Bans the Gun Design Itself
Instead of targeting the illegal switch, SB 334 bans every pistol that contains a cruciform trigger bar — because it could theoretically be converted. The gun is the target, not the crime.
Here's What You're Facing
The penalty structure escalates rapidly — especially if a banned pistol is connected to any other offense.
General Violation — Sell, Buy, or Transfer
Misdemeanor. Up to 3 years imprisonment and/or a $5,000 fine for selling, buying, or transferring a "machine gun convertible pistol" after January 1, 2027.
Used During a Felony or Crime of Violence — 1st Offense
Mandatory minimum 5 years, up to 20 years in prison. Court cannot go below 5 years. Sentence cannot be suspended. No parole eligibility for 5 years. This is on top of any other sentence.
Used During a Crime — Subsequent Offense
Mandatory minimum 10 years, up to 20 years. Cannot be reduced below 10. Cannot be suspended. No parole for 10 years. Stacked on any other sentence.

They're Banning the Gun, Not the Crime
The Switch Is Already a Federal Felony
Installing a Glock switch (auto-sear) is already illegal under federal law — it's a violation of the National Firearms Act carrying up to 10 years in federal prison. ATF actively prosecutes these cases. The people installing switches on Glocks are already committing a serious federal crime.
SB 334 doesn't go after the people installing switches. It goes after the design of the gun itself. Maryland is saying that because a criminal could illegally modify a Glock, the gun shouldn't be sold to anyone — including the millions of law-abiding owners who would never touch a switch.
The cruciform trigger bar is a standard design element of Glock pistols. It's not a defect. It's not an accessory. It's how the gun was engineered to function. Banning every pistol that uses this design is like banning every car with a gas pedal because someone could drive it into a crowd.
The Scope of This Ban
Most Popular Handgun in America
Glock is the best-selling handgun manufacturer in the U.S. and the standard-issue sidearm for most American law enforcement agencies.
U.S. Law Enforcement Market Share
Roughly 65% of American law enforcement agencies issue Glock pistols. The bill exempts police — but not the citizens they serve.
Effective Date: 2027
If signed into law, the ban on sales takes effect January 1, 2027. Existing owners can keep their guns but cannot sell or transfer them in Maryland.
Senate Vote
Passed the Maryland Senate with a comfortable margin. House Judiciary Committee reported favorable with amendments on April 6, 2026. Heading to the House floor.
No Other State Has Done This
Multiple states restrict certain firearm types — but banning commonly-owned handguns based on their theoretical convertibility is unprecedented.
| State | Standard Glock Sale | Auto-Sear / Switch | Approach |
|---|---|---|---|
| Maryland (SB 334) | Banned | Banned | Ban the gun design itself |
| California | Roster Only | Banned | Handgun roster limits models, not design type |
| New York | Legal | Banned | Ban the conversion device |
| Illinois | Legal | Banned | Ban the conversion device |
| Virginia | Legal | Banned | Ban the conversion device |
| Federal Law | Legal | Felony | NFA violation — up to 10 years federal prison |
Maryland isn't banning machine guns. They're banning the most popular handgun in America because a criminal could theoretically turn it into one — something that's already a federal felony.
