Connecticut’s New “Convertible Pistol” Ban: What Public Act 26-41 Means

On May 26, 2026, Governor Ned Lamont signed Public Act 26-41 into law, creating new criminal restrictions on handguns that can be quickly turned into fully automatic weapons. The law takes effect October 1, 2026, and it reaches beyond just convertible pistols—it also touches unfinished frames and lower receivers, voluntary firearm surrender, and gun permit fees. Here’s a practical breakdown of what changed and who it affects.

The Core Problem the Law Targets

The law responds to a nationwide rise in “switches”—small conversion devices, some no larger than a Lego brick, that can turn an ordinary semiautomatic pistol into a machine gun. The scale is significant: between 2019 and 2023, the ATF recovered more than 31,000 conversion devices nationally, and the Hartford Police Department alone seized 51 switches between 2023 and 2024.

The concern driving the legislation is straightforward. A single person with a converted weapon can fire a high volume of rounds in seconds, which raises the risk of mass-casualty incidents and makes it harder for law enforcement to respond safely. Machine guns are already illegal in every state, including Connecticut—this law goes after the design and sale of pistols built in a way that makes conversion easy.

What Counts as a “Convertible Pistol”

The statute defines a convertible pistol as any semiautomatic pistol with a cruciform trigger bar that can be readily altered—by hand or with a common household tool—so that a pistol converter can turn it into a machine gun.

A few definitions matter here:

• A cruciform trigger bar is the component linking the trigger and firing pin, with its sear set in a cross-shaped surface.
• A common household tool is defined broadly: a knife, screwdriver, wrench, hacksaw, crowbar, drill, rotary tool, hammer, chisel, file, or pliers, among others.
• A pistol converter is a device attached to the rear of the slide that interferes with the trigger mechanism so the pistol can fire rapidly or automatically with one continuous trigger pull.

Importantly, the definition carves out two categories. It does not include (1) hammer-fired semiautomatic pistols, or (2) pistols whose cruciform trigger bar is shielded by a molded tab or piece of material—unless that tab can be readily removed. This is the design standard the Governor described: manufacturers must build pistols so they can’t easily be converted.

The New Crime

Section 3 creates the central offense. Any person or business that knowingly imports, advertises, sells, or offers for salea convertible pistol manufactured on or after October 1, 2026, is guilty of a class D felony—punishable by up to five years in prison, a fine of up to $5,000, or both.

There’s a notable limitation: the new selling offense does not apply to a private, non-dealer sale or lawful transfer between two people who are not licensed gun dealers. The prohibition is aimed primarily at importers, manufacturers, dealers, and commercial sellers, not private transfers between individuals.

Separately, the law folds convertible pistols into the existing “machine gun” definitions under sections 53-202 and 53a-3. A convertible pistol that is actually equipped with a pistol converter is now treated as a machine gun—meaning possession of the pistol together with a converter carries the full weight of Connecticut’s machine gun statutes.

What Else the Act Does

Despite its name, Public Act 26-41 covers more ground than convertible pistols:

Unfinished frames and lower receivers. The law rewrites the definition of an “unfinished frame or unfinished lower receiver” to capture any blank, casting, forging, printing, extrusion, or similar item that either (1) has reached a stage where it can readily be completed into a working firearm frame, or (2) is marketed or sold to the public to be used as one. This broadens the prior definition and tightens regulation of “ghost gun” components. Violations remain a class C felony, with enhanced penalties (class B felony) where the item is stolen or has an altered serial number.

Voluntary relinquishment of firearms. A new provision lets any individual voluntarily surrender firearms or ammunition to state police or a local department for safekeeping, for a period of at least 14 days. The person can request the return on or after the 15th day, up to two years later, provided they remain legally eligible to possess the firearm. Anything not reclaimed within two years is destroyed, after written notice.

Permit fee refundability. The Act adjusts the rules on refunds for retail firearm sale permits and pistol/revolver carry permits, clarifying when fees—or portions of them—can be refunded if a permit isn’t issued or renewed, or if the local permitting authority misses statutory deadlines.

Law Enforcement’s Position

The legislation drew written support from the Connecticut Police Chiefs Association, which represents the chiefs overseeing roughly 100 agencies and more than 7,000 officers statewide. In its testimony to the Judiciary Committee, the CPCA reported a rise over the past decade in firearms modified with switches—often using instructions found online—and noted that chiefs in larger urban municipalities have seen more such weapons in recent seizures. The association backed the increased penalties, expressing hope they would reduce the number of switches on the streets.

The Bigger Picture

Public Act 26-41 fits a pattern of Connecticut gun-safety legislation over the past several years: Ethan’s Law (PA 19-5) on safe storage, the ghost gun law (PA 19-6), the comprehensive 2023 package (PA 23-53), and the 2025 industry-responsibility law (PA 25-43). The Governor framed this latest measure as keeping the state’s gun-violence-prevention laws current with emerging weapons technology—and as state-level action in the absence of federal legislation.

Bottom Line

If you manufacture, import, or sell firearms in Connecticut, the October 1, 2026 effective date is the key deadline. Convertible pistols made on or after that date can’t be commercially imported or sold here without exposure to felony liability, and the design carve-outs (hammer-fired pistols and shielded trigger bars) define the safe harbor. For everyday gun owners, the private-transfer exception means person-to-person sales aren’t swept into the new selling offense—but possessing a covered pistol together with a converter now triggers machine gun treatment.
