What type of firearm registration system does Hawaii use?

Hawaii uses a universal registration system for firearms. This means that all firearms in the state must be registered with the appropriate authorities. This type of registration system helps ensure that the government has a record of all firearms within the state, which can aid in tracking weapons and preventing illegal activities. Additionally, it allows for better regulation and oversight of firearms to help maintain public safety. The other options are incorrect because Hawaii does require registration for all firearms, making it a universal registration system.
