Rhode Island is both a "may issue" and "shall issue" state depending on the party issuing the permit. Most local authorities are considered "shall issue" while any given by Rhode Island's attorney general are "may issue". The attorney general does not normally issue permits unless that applicant is retired law enforcement, and since many local governments defer to them it can be very hard to obtain a permit.
