Gun Law Ranking – Open Society Institute
Definition and Selection Criteria
In its Comparative Survey of State Firearm Laws, the Open Society Institute ranked American states on the strength of their firearm legislation. If a state received full points on all criteria, it would score a total of 100 points.
In this assessment, the states’ total scores ranged from a high of 76 points (strong) to –10 points (very weak). A negative score indicates a state that has very limited gun control laws of its own, and which according to OSI undermines the minimum standards in US federal law.
