The Second Amendment Foundation, National Rifle Association, and Firearms Policy Coalition aren’t waiting for Maryland’s Glock ban to land—they’re already in federal court trying to stop it cold before the January 1, 2027 trigger date. Their motion argues that SB 334 is a thinly veiled attempt to outlaw some of the most common, lawfully owned handguns in America under the guise of regulating “switches,” even though those illegal devices are already banned under existing federal and state law. By targeting the Glock platform itself rather than the actual criminal misuse, Maryland is essentially asking the courts to bless a ban on a class of arms that millions of law-abiding citizens rely on for self-defense, a move that flies in the face of the Supreme Court’s Bruen framework requiring the state to prove a historical tradition of such restrictions.

What makes this challenge especially sharp is the timing and the coalition behind it. With three of the most active and well-funded 2A groups coordinating, the case could become a proving ground for how lower courts apply Bruen’s text-and-history test to modern handgun restrictions. If the judge grants the preliminary injunction, it would send a clear signal that states cannot simply rebrand popular firearms as “assault weapons” or “machine-gun conversion platforms” to evade constitutional scrutiny. Conversely, a denial would likely accelerate appeals and keep the pressure on the Fourth Circuit, where outcomes on carry and magazine cases have been mixed. Either way, the litigation is already forcing Maryland to defend a law that appears more about political signaling than addressing the real problem of illegal switches already on the books.

For the broader 2A community, this isn’t just about Glocks in Maryland—it’s about whether incremental bans on the most popular defensive handguns can survive constitutional review. The coordinated legal push shows that groups are learning to strike early, before enforcement begins, rather than waiting for confiscation schemes to take root. If successful, the injunction would preserve access to reliable, widely available platforms while the underlying constitutional questions play out, buying time and precedent that could blunt similar efforts in other states. The message is clear: the gun-control playbook of banning what’s common and calling it dangerous is running into increasingly organized and well-resourced resistance.
