According to certain aspects, a system for controlling use of firearms can include a circuitry coupled to a firearm and in communication with a Global Positioning System (GPS) unit. The circuitry may be configured to: determine, using the GPS unit, coordinates of a current location of the firearm; transmit the coordinates of the current location of the firearm to a remote server, wherein the remote server comprises a database including a plurality of coordinates associated with a plurality of locations at which the firearm should be enabled or disabled; receive from the remote server information relating to whether the firearm should be disabled at the coordinates of the current location of the firearm; and in response to determining that the firearm should be disabled based on the information from the remote server, initiate disabling of the firearm.
