Status: On the Governor's desk
Maryland's legislature passed a bill banning the sale of Glocks and every pistol built around a cruciform trigger bar. They are targeting an internal part to outlaw the most popular handgun in America. Here is exactly what it does.
SB 334 creates a brand new category of outlawed firearm: the "machine gun convertible pistol." It bans anyone from making, selling, buying, receiving, or transferring a semiautomatic pistol that uses a cruciform trigger bar and can be switched to full-auto fire by snapping an illegal auto-sear ("Glock switch") onto the back of the slide.
This is not the old Maryland Handgun Roster. It is a new criminal prohibition. A pistol that already cleared the roster becomes illegal to sell the moment it fits this definition.
The cruciform trigger bar is the cross-shaped part that catches the striker between shots. It is the defining feature of the Glock fire control system. Every Glock ever made uses it. By writing the ban around that one part, the state sweeps in the whole platform.
Glock redesigned its pistols to resist switch installation. SB 334 anticipated that. A gun is still banned even if it carries blocking material, as long as that material can be removed with a common household tool. The redesign does not save it.
A Glock switch is a coin-sized device that converts a pistol to full auto. It can empty a 17-round magazine in under a second. It is already a federal felony to possess, carrying up to 10 years in prison, whether or not it is attached to a gun.
The recovery numbers are why legislators say they are acting.
The switch is the crime. SB 334 does not ban the switch any harder than federal law already does. It bans the legal host pistol owned by millions of people who will never touch a switch. A felon building a switch on a 3D printer is not waiting on a Maryland sales permit.
| Platform | Examples | Status |
|---|---|---|
| Glock, Gen 1–5 | G17, G19, G26, G43, G45, and the rest | Banned |
| Glock "V Series" | Redesign still uses the cruciform bar | Banned |
| Shadow Systems | MR920, DR920, CR920, XR920 | Banned |
| PSA Dagger / Polymer80 | Glock-pattern clones and builds | Banned |
| S&W M&P, SIG P320, Springfield XD | Striker-fired, different fire control | Not hit |
| Hammer-fired & revolvers | 1911, CZ 75, Beretta 92, wheelguns | Not hit |
The Maryland State Police must publish a list of specifically prohibited models before the ban takes hold. The scope beyond Glock-pattern guns gets decided by regulators, with no further vote required. The state's own fiscal note admits the police are unlikely to finish that list by the January 1, 2027 deadline.
This is not a fringe firearm. The Glock 19 is the best-selling handgun in America, and Glock-pattern pistols sit in tens of millions of lawful hands.
Under Heller, arms "in common use for lawful purposes" cannot be banned. There may be no firearm in America more plainly in common use than a Glock.
With no transfer path outside family and inheritance, the second-hand Glock market in Maryland is finished. Ownership is grandfathered. Transferability is not.
Active and retired law enforcement are fully exempt. So are licensed dealers, for servicing and out-of-state transfers. Existing owners keep what they have.
Police can buy and carry the exact pistols that become criminal contraband for everyone else. The people enforcing the ban are written out of it.
| Violation | Charge | Exposure |
|---|---|---|
| Sell, buy, receive, or transfer | Misdemeanor | Up to 3 yrs + $5,000 |
| Use of the weapon in a felony or violent crime | Enhanced | 5-yr min, 20 max · 10-yr min on a repeat |
The enhanced sentence is mandatory, nonsuspendable, and nonparolable. The base offense, though, is the one aimed at ordinary buyers and sellers.
Maryland Shall Issue calls SB 334 "blatantly unconstitutional" and says the complaint is already written, ready to file the moment Moore signs. The NSSF has vowed to take Attorney General Anthony Brown to court, and NRA-ILA has lined up against the bill too.
California got there first with AB 1127, signed in October 2025, with its dealer-sales ban set for July 1, 2026. It is already being challenged in Jaymes v. Bonta by the Second Amendment Foundation, the NRA, and the Firearms Policy Coalition. Maryland would be the second state in, and that California ruling will shape this fight.
Under Bruen, a gun law has to match the nation's historical tradition of regulation. There is no founding-era tradition of banning ordinary arms because a criminal might illegally modify them. Pair that with the Heller common-use test and the state is defending shaky ground.
Democrats hold a veto-proof supermajority, 34 to 13 in the Senate and 102 to 39 in the House. Even if Moore balked, the votes to override are already there. This bill becomes law one way or another.
Maryland is not acting alone. Gun-control groups are pushing the same model language across blue states at once. If it survives the courts, expect it to spread fast.
| State | Status | Effective |
|---|---|---|
| California · AB 1127 | Signed, now in court | Jul 1, 2026 |
| Maryland · SB 334 | On Governor's desk | Jan 1, 2027 |
| Connecticut · HB 5043 | Passed the House | TBD |
| Illinois · HB 4471 | In committee | TBD |
| New York | Pending | TBD |
The switch is already a felony. So they are banning the gun instead.
Framed as a fix for the switch epidemic, SB 334 functionally bans the most popular handgun platform in America from future sale in Maryland. It almost certainly gets signed, and it almost certainly gets sued.
The practical advice is simple. If you want a Glock or a Glock-pattern pistol in Maryland, buy it before January 1, 2027. After that, your only routes are inheritance or watching the litigation play out.
