A weapons offense involving prohibited possession, transfer, carrying, or use of a regulated weapon or related device. It is defined by prohibited status, location restrictions, registration requirements, or prohibited conduct elements where applicable. It does not include lawful possession or handling that satisfies all authorization and compliance requirements. It addresses public safety risk and often carries enhancements and collateral restrictions upon conviction. The concept is generally stable, though regulated-item lists and thresholds evolve over time.

Principle

Registration regimes create recordkeeping and traceability obligations; possession becomes unlawful when the statutory registration requirement is unmet and the possessor lacks an exemption or completed retroactive compliance allowed by law.

Demonstration

An individual inherits a handgun and fails to complete the jurisdiction's mandatory registration within the legally prescribed period; later, during a traffic stop, the registration status is discovered and the individual is charged with possession of an unregistered firearm.

Misapplication

Applying the offense where the firearm is exempt from registration under statute (for example certain antiques, curio pieces, or specially licensed firearms) or where registration occurred in a different registry recognized by law absent proper cross-jurisdictional rules.

Consequence

Correct application leads to administrative sanctions, criminal charges, potential confiscation of the firearm, and requirements to register or forfeit the weapon; it also preserves the public-policy goal of traceability for investigations.

Reversal

The reversal is possession of a lawfully registered firearm, where the record shows compliance with registration obligations and the possessor holds any necessary certificates or permits.

Boundary

Scope limited to firearms subject to a legal registration duty; typically excludes weapons not defined as firearms, items registered under reporter exemptions, and situations where the law provides conditional forgiveness or late-registration procedures.

Semantic Tension

Tension exists with 'possession of a prohibited weapon' and with regulatory licensing offenses; unregistered possession targets lack of record rather than categorical prohibition, so an item may be legal to possess if registered but illegal if not.

Synthesis

Possession of an unregistered firearm is a regulatory offense rooted in the statutory duty to register certain firearms; culpability depends on possession combined with the absence of required registration and any applicable exemptions or remedial pathways.
