Maryland Lawmakers Pass Ban on “Machine Gun Convertible Pistols”

Maryland is moving to restrict the sale of some of the most popular handguns in the United States. Lawmakers in Annapolis have passed Senate Bill 334, a piece of legislation designed to ban the manufacture, sale, purchase, and transfer of “machine gun convertible pistols” within the state.

The bill passed the House of Delegates on April 8, 2026, with a vote of 92-39, following a 28-16 approval by the Senate in March. The legislation now awaits the signature of Governor Wes Moore.

Understanding the “Machine Gun Convertible” Ban

Although the legislation does not explicitly name a specific brand, it targets semi-automatic pistols that utilize a cruciform trigger bar. This specific component is a safety mechanism primarily found in Glock pistols and similar copycat weapons. The cruciform trigger bar is designed to limit the firearm to a single round of fire per trigger pull and prevent accidental discharges.

Supporters of the bill argue that this specific design makes the firearms “readily convertible” into automatic weapons. According to lawmakers, these pistols can be modified into machine guns using common household tools, such as an electric drill or a screwdriver, or by adding a small device known as a “Glock switch.”

The Role of “Glock Switches” in Crime

Several law enforcement agencies, including the Baltimore Police Department, supported the measure due to the prevalence of modified pistols in criminal activity. One cited example is an October 2023 mass shooting at Morgan State University, where the handgun used had been modified with a Glock switch to fire automatically.

Opposition and Industry Pushback

The bill has faced significant criticism from law enforcement officials and firearm retailers who argue that the legislation unfairly singles out a dependable brand.

• Law Enforcement Perspective: Wicomico County Sheriff Mike Lewis argued that any individual with a working knowledge of weapons can modify a firearm from semi-automatic to fully automatic, regardless of the model.
• Retail Impact: Jamie Wink, owner of Wink’s Sporting Goods, noted that Glocks are a top choice for customers due to their reliability and safety, accounting for approximately 50% of all handgun sales at his store.

Key Takeaways and Timeline

• Effective Date: If signed into law, the ban on the manufacture, sale, purchase, and transfer of these pistols begins January 1, 2027.
• Scope: The ban focuses on pistols with a cruciform trigger bar, effectively targeting Glocks and similar designs.
• Legal Precedent: Maryland would become the second state in the U.S. To implement such a ban, following similar legislation in California.
• Legal Challenges: Gun rights groups have indicated they intend to challenge the law in court.
