Dozens of supporters of gun rights rallied at the Capitol today.

They're waiting for a ruling from the Missouri Supreme Court on a challenge to a new law that would allow most residents to carry concealed weapons.

House member Larry Crawford, who sponsored the concealed guns measure, today urged advocates to be patient. He said gun rights supporters need to be careful not to do or say anything to jeopardize the court's ultimate decision. And he asked them not to call the Supreme Court to check on the status of the case.

Rally participants wore buttons reading "Guns Save Lives."

They also heard from several legislators who supported the concealed guns bill last year.
