U.S. District Judge Frederick J. Scullin on Tuesday stayed his ruling from going into effect until Oct. 22.
In a ruling that became public on Saturday, Scullin struck down the city's ban. He wrote that the Second Amendment gives people the right to carry a handgun outside the home for self-defense.
The group that had brought the lawsuit against the city did not oppose a 90-day stay. Lawyers for the city want Scullin to stay the ruling while they appeal, but he will not rule on that request until at least August.
