HB 1823 revises Missouri’s weapons statutes by repealing and reenacting sections 571.010 and 571.020 to update definitions and prohibited conduct related to certain weapons and devices. The bill defines a range of terms including explosive weapon, firearm, knife, switchblade knife, machine gun, short-barreled rifle or shotgun, firearm silencer, gas gun, knuckles, and, notably, a large-capacity ammunition feeding device as a magazine, belt, drum, feed strip, or similar device capable of holding more than ten rounds. It also refines the definition of antique firearm and other weapon-related terms used in the chapter.
The bill makes it an offense to knowingly possess, manufacture, transport, repair, or sell an explosive weapon, explosive/incendiary/poison material intended for such a weapon, a gas gun, an explosive bullet or projectile, knuckles, a large-capacity ammunition feeding device, or certain federally regulated items when possessed in violation of federal law, including machine guns, short-barreled rifles or shotguns, firearm silencers, and switchblade knives. It preserves exceptions for conduct tied to official duties, lawful commercial transactions, industrial use, museum display, and dramatic performances. Violations involving explosive weapons and related materials are classified as class D felonies, while offenses involving bullets/projectiles, knuckles, large-capacity ammunition feeding devices, and the federally regulated items are class A misdemeanors.
The bill’s impact would be to expand and clarify Missouri criminal law governing weapons possession, especially by expressly adding large-capacity ammunition feeding devices to the list of prohibited items. It would affect gun owners, sellers, manufacturers, and others handling regulated weapons or accessories, while also incorporating federal-law compliance into the state offense structure. Because it rewrites core definitional sections, it would also influence how prosecutors and courts interpret weapons-related offenses under chapter 571.
The available context suggests the bill was introduced as a firearms-restriction measure and referred to the Emerging Issues Committee, but there are no recorded committee transcripts or votes in the provided materials. Based on the bill text and caption, the general sentiment appears to favor tighter regulation of certain weapons and accessories. At the same time, the most likely point of contention is the inclusion of large-capacity ammunition feeding devices and other commonly debated firearm-related items, which would be viewed by supporters as a public-safety measure and by opponents as a restriction on lawful gun ownership and commerce.
HB 1823 would amend Missouri’s weapons code by replacing the existing statutory definitions in sections 571.010 and 571.020 and adding large-capacity ammunition feeding devices to the list of prohibited items. It would create or clarify criminal liability for possession, manufacture, transport, repair, or sale of specified weapons and accessories, while preserving enumerated exceptions and setting misdemeanor/felony penalties for different categories of conduct.
No committee testimony or recorded votes are provided, so there is no direct evidence of debate positions. The bill’s caption and text indicate a generally restrictive approach to weapons regulation, suggesting support from lawmakers favoring public-safety restrictions on dangerous weapons and accessories. The absence of recorded opposition in the supplied materials prevents a definitive assessment, but the subject matter is the kind that typically draws disagreement over gun rights versus regulation.
The main likely point of contention is the bill’s treatment of large-capacity ammunition feeding devices, which are expressly added to the prohibited items list and are often controversial in firearms policy debates. Additional friction may arise from the inclusion of switchblade knives, silencers, short-barreled rifles and shotguns, and federal-law cross-references, since critics may argue these provisions broaden criminal exposure for otherwise lawful conduct. Supporters would likely emphasize the bill’s public-safety purpose and its focus on dangerous or heavily regulated weapons.
