State Firearm Legality Matrix (2026)

Statute-cited, every class verified on or after 2026-07-10

This matrix tracks the legality of five product classes across all 50 states and Washington, D.C.: forced reset triggers, binary triggers, suppressors, magazine capacity limits, and assault-weapon feature bans. Each is a distinct area of state law, and they do not move together; a device legal under federal law can still be a felony to possess in California, New York, or New Jersey, and a state that bans one class often leaves another untouched.

The restricted counts as of the July 2026 verification: forced reset triggers are restricted in 15 jurisdictions, binary triggers in 12 states plus two ambiguous jurisdictions, suppressors banned in eight states plus D.C. (legal in 42 states), magazine capacity capped in 13 states plus D.C., and assault-weapon feature bans in 11 states plus D.C. Every restricted cell in the tables below links to the controlling statute or court decision, and each class carries its own last-verified date, so you can confirm the source yourself.

The asymmetries are where people get caught. Washington bans binary triggers but not forced reset triggers; Nevada is the reverse. Delaware's magazine limit is 17 rounds, not the 10 or 15 most states use. Suppressors are legal to own in Connecticut but cannot be used while hunting. Minnesota's binary-trigger ban was struck down in May 2026 while its forced-reset prong survived. Colorado's SB25-003 split its own timeline: the rapid-fire device ban has been in force since April 2025, while the semi-auto purchase-permit regime starts August 1, 2026.
