A gun lock for use in securing a weapon within a gun rack of a police vehicle or the like utilizes a housing supporting a pair of curved lock gates in curved travel paths between an abutting closed configuration and a separated open configuration. The curved lock gates are constrained in curved travel paths by a top plate and a lower plate and each define a curved gear rack. A coupling gear is rotatably supported within the housing and simultaneously engages both curved gear racks to provide movement of the lock gates between open and closed configuration. A solenoid operated latching mechanism secures the lock gates from movement away from the closed and locked configuration in the absence of an electrical activation. A key override is provided in the event of an electrical failure within the host vehicle.
