District of Columbia Magazine Capacity Limit

D.C. Code section 7-2506.01 defines a large-capacity ammunition feeding device as a magazine, belt, drum, feed strip, or similar device that accepts, or can readily be restored or converted to accept, more than 10 rounds. The definition excludes an attached .22-caliber tubular device.

The D.C. Court of Appeals granted en banc rehearing in Benson v. United States in April 2026 and vacated the panel disposition. That procedural step left the statutory question for the full court rather than making the panel opinion the final controlling judgment.

There is no federal magazine capacity limit; the 1994 federal assault weapons ban expired in 2004.

Scope: Detachable magazine round-count restrictions for handguns and long guns. States not listed have no capacity limit.
