Lewis' manager, Claudia Marghilano, says the handgun is a hollowed-out prop gun that Lewis sometimes twirls during his show.
She tells The Associated Press that the gun couldn't fire.
Marghilano says Lewis didn't know the gun was in the bag along with other props.
Cassell says if the gun were merely a prop "it wouldn't be a weapon and we couldn't cite him for carrying a weapon."
