Maryland Glock Ban: Groups Move to Block SB 334 (2026)

The Maryland Glock ban is heading for a courtroom showdown. In July 2026, a coalition of gun-rights groups asked a federal court to freeze Senate Bill 334 — Maryland’s new law targeting “machine gun convertible pistols” — before it takes effect. Here is what the law does, who is fighting it, and why it matters.

The short version: On July 21, 2026, the Second Amendment Foundation, Firearms Policy Coalition, and National Rifle Association filed a motion for a preliminary injunction to block Maryland’s SB 334 in the case Bathras v. Moore. The law, signed by Governor Wes Moore, bans pistols with a “cruciform trigger bar” — a feature in every Glock — and is set to take effect January 1, 2027. The challengers want it stopped first.

What the Maryland Glock ban (SB 334) does

SB 334 prohibits making, selling, buying, or transferring what it calls “machine gun convertible pistols.” The law defines that category by the presence of a cruciform trigger bar — a design element found in all Glock handguns, among the most commonly owned pistols in the country. Supporters say the goal is to curb illegal conversion of pistols to fully automatic fire using aftermarket “switches.”

The reach, however, is broad. Because the trigger-bar definition sweeps in standard, unmodified Glocks, critics argue the law effectively bans a hugely popular class of ordinary handguns rather than the illegal conversion devices themselves.

The lawsuit: Bathras v. Moore

The challenge was filed in May 2026 by the Second Amendment Foundation, the retailer Atlantic Guns, the National Rifle Association, the Firearms Policy Coalition, and two private citizens. On July 21, 2026, the plaintiffs escalated by asking the court for a preliminary injunction — a court order to freeze enforcement of SB 334 while the case is decided, rather than waiting for the January 2027 effective date to arrive.

The legal argument against the Maryland Glock ban

The core argument is straightforward. In District of Columbia v. Heller, the Supreme Court held that handguns are “quintessential” self-defense arms protected by the Second Amendment. The challengers contend that SB 334 bans exactly that — common, legal handguns — in the name of preventing a separate crime, illegal full-auto conversion. As one filing framed it, you cannot ban lawful conduct wholesale simply because a few people misuse it.

What happens next

The court will now weigh the injunction request. If it grants the motion, SB 334 is paused before it ever takes effect; if it denies the motion, the January 1, 2027 date looms while the case continues. This article explains the litigation; it is not legal advice, so Maryland owners should confirm the current law with a qualified attorney.
