Does Hawaii Have an Assault Weapons Ban?

Hawaii's feature definition is specific to a semiautomatic pistol that accepts a detachable magazine. Section 134-1 requires two or more of three characteristics: a magazine attaching outside the pistol grip, a threaded barrel capable of accepting listed muzzle or handgrip devices, and a barrel shroud.

Section 134-8 applies the possession, manufacture, sale, transfer, and acquisition provisions to the resulting assault-pistol category. The definition should not be converted into a one-feature test or applied to a rifle merely because the rifle shares parts with a pistol platform.

There has been no federal assault weapons ban since the 1994 ban expired in 2004; no feature restrictions apply federally to semi-automatic rifles or pistols. The 2023 ATF pistol-brace rule was vacated nationwide and is not enforced, but federal SBR classification for a brace-equipped firearm still turns on whether the specific weapon is designed and intended to be fired from the shoulder. Cargill v. Garland (2024) made bump stocks federally legal. Feature bans are entirely a matter of state law.

Scope: State laws restricting semi-automatic rifles, pistols, and shotguns by configuration features: threaded barrels, pistol grips, folding or telescoping stocks, flash suppressors, forward grips, and similar. Magazine capacity limits are tracked as a separate class.
