ANNAPOLIS — The Maryland General Assembly passed the Stop DIY Machine Guns Act (SB 334/HB 577) legislation introduced by Public Safety Subcommittee Chairwoman, Delegate Nicole Williams.
“Today, my colleagues and I took another step forward that will help keep Maryland families safe from gun violence,” said Delegate Nicole Williams. “By ensuring that pistols sold in our state cannot be easily converted into machine guns that fire up to 20 rounds per second, we are taking active steps to reduce crime, reduce bloodshed and keep families safe.”
The legislation requires that all pistols sold in the state of Maryland are designed to prevent quick and easy modifications that allow certain firearms to be converted into an illegal, fully automatic machine gun.
At present, so-called “Glock switches” are tiny pieces of metal or plastic that can be added to certain pistols. Such devices, despite being illegal under federal and Maryland laws, can be purchased for as little as $25 or printed at home using a 3D printer.
In 2025, these modifications were found at at least four crime scenes in Maryland as well as the Morgan State University mass shooting in 2023.
The legislation was supported by community and gun violence prevention organizations.
“Maryland has long been a national leader in the fight against gun violence, and today’s House vote proves that commitment remains ironclad. We are incredibly grateful to Delegate Nicole Williams for her leadership in tackling the urgent threat of DIY machine guns by holding the gun industry accountable for their dangerous designs,” said Monisha Henley, Senior Vice President for Government Affairs at Everytown for Gun Safety. “By passing this legislation, Maryland is taking an innovative step to stop the sale of ‘convertible’ pistols that are easily transformed into weapons of war. This bill focuses on prevention by stopping these convertible weapons at the source before they can devastate our communities. We applaud the House for prioritizing the safety of Maryland families over the profits of negligent manufacturers.”
“I applaud my colleagues and our community supporters for their ongoing efforts to advance critical and lifesaving legislation like the Stop DIY Machine Guns Act,” added Delegate Williams. “I look forward to our continued partnership that advances commonsense, lifesaving legislation.”
So are Glock handguns now illegal in MD?
This law impacts law abiding citizens. The criminals will acquire firearms on the black market and convert to full auto without any permits, license or fees. I would speculate that the firearms found at crime scenes were illegal and possessed by CRIMINALS.
Maryland continues to impose these ridiculous regulations on law abiding citizens only to support there gun control agenda.
All this bill dose is mess with legal gun owners, like no one will bring a glock or a switch from another state… this is another feel good law that makes criminals out of legal gun owners…
