Are municipalities in Iowa allowed to enact their own firearms ordinances?

Municipalities in Iowa are not allowed to enact their own firearms ordinances because state law preempts local laws. This means that state law takes precedence over local laws and regulations. Therefore, even if a municipality were to enact an ordinance related to firearms, it would not be valid as it would be in conflict with state law. Options A, B, and D are incorrect because they suggest that municipalities can have some control over firearms ordinances, which is not the case in Iowa. This is an important distinction to keep in mind to ensure compliance with state laws.
