The number of states allowing concealed carry permits is increasing, and states
broadly differ in eligibility requirements and the extent to which they have
reciprocity agreements. In June 2002, 7 states and the District of Columbia
prohibited the concealed carry of handguns. As of March 2012, individuals can
carry concealed handguns in all but 1 state (Illinois) and the District of Columbia
(see fig. below). "Shall-issue" states-in which issuing authorities are required to
issue a permit to an applicant that fulfills the objective statutory criteria-
generally issue more permits than states with greater discretion in granting
permits ("may-issue" states). Because of differing eligibility requirements, some
states would issue a permit to an applicant, while others would not. For example,
some states define what constitutes a disqualifying felony differently or have
different firearms training requirements. As of March 2012, 39 states that issue
permits and Vermont (permits not required) recognize concealed carry permits
from other states. Of the 9 states that do not grant reciprocity, 8 are may-issue
states.
