DENVER (AP) — Fiercely debated ammunition limits have cleared Colorado's Democratic Legislature and are on their way to the governor, who has said he'll sign the measure into law.

The 15-round magazine limit would make Colorado the first state outside the East Coast to ratchet back gun rights after last year's deadly shooting rampages.

Colorado's gun-control debates have been closely watched because of the state's gun-loving frontier heritage and painful history of mass shootings.
