As of 2015, a map of states where carrying concealed weapons is legal can be found on the USA carry site. The map also shows if it is legal for just residents or non-residents as well.
The USA Carry site lets users click on a state within the map for specific gun carrying laws and rights for that state. Articles and information on the NRA are also available.
The Handgun Law U.S. site is another location where visitors can find a map for concealed carry laws. Visitors can select areas in order to find out if their permits apply when visiting other states.
