the list was based on these five things
As we have done for several years now, we have evaluated each state numerically for 2019 in each of these five categories: Right-To-Carry/Concealed Carry Weapon (CCW), access to Black Rifles, the states’ Use-of-Force laws (also known as Castle Doctrine), the prohibition of items regulated by the National Firearms Act (NFA), and a catch-all Miscellaneous column. States are awarded 0-10 points in each category and ranked according to their total number of points. In the case of a tie, which is common, we dig deeper into the Miscellaneous category and rank states accordingly. Please note that while we have done our best to rank states as objectively as possible, you my disagree with our findings. No article of this length and researched by a single author could capture every nuance of a state’s statutory and regulatory framework.
