Yes. Minnesota's binary trigger ban was struck down in state court; binary triggers are currently lawful.
Litigation Status and Details
The 2024 binary-trigger prong of Minn. Stat. § 609.67 (added by 2024 c 127) was struck down and severed as violating the state single-subject clause in Minnesota Gun Owners Caucus v. Walz (Minn. Ct. App., affirmed May 26, 2026). The ruling is procedural, not a Second Amendment holding; the legislature could re-enact a standalone ban. The FRT-reaching 2023 prong of the same statute survives.

Federal baseline
Binary triggers are legal under federal law and are not machine guns under 26 U.S.C. § 5845(b); ATF treats the trigger pull and the trigger release as two separate functions of the trigger, so one round is fired per function. Cargill v. Garland (2024) concerned bump stocks, not binary triggers, and does not change this.
Scope: Binary triggers (Franklin Armory BFSIII and similar): fire one round on trigger pull and one on release. Forced reset triggers are a separate class.
