Maryland HB577 would create offense for possession/manufacture of 'machine gun convertible pistols'; bill in committee
State bill HB577 — Maryland — status: in committee
Official title: Criminal Law - Firearm Crimes - Machine Gun Convertible Pistols
What it does
HB577 (2026) would create a distinct criminal offense for machine gun "convertible pistols," defining and prohibiting their manufacture, sale, transfer, and possession and prescribing criminal penalties. The measure was rereferred to the House Judicial Proceedings Committee on April 10, 2026, and remains in committee consideration.
Industry impact
If enacted, the law would require Maryland manufacturers and retailers to stop producing, importing, or offering for sale any pistol or device that the statute defines as a machine gun convertible pistol, or face criminal exposure; existing compliance policies tied to federal NFA/machinegun rules may not be sufficient if the state definition is broader. Businesses that currently make, distribute, or service conversion devices or similar components would need to review product lines and inventory, adjust sales and transfer screening, and may discontinue affected items. NFA/SOT holders who possess items that meet the bill's definition could face state criminal liability unless the bill exempts federally registered items — the bill text should be checked for any registration or grandfathering provisions.
