Contested entry
Delaware's rapid fire device definition (a device that increases the rate of fire beyond what is possible unassisted) reaches binary triggers; classed with destructive weapons (class E felony).
The statute in practice
Title 11, section 1444 places a 'rapid fire device' within Delaware's destructive-weapons chapter and covers manufacture, sale, transfer, purchase, receipt, and possession. Its device definition turns on increasing a semiautomatic firearm's rate beyond the rate attainable without the device, not solely on the federal one-shot-per-trigger-function test.
Federal law
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.
