An aerosol dispensing system has a container assembly, an actuator assembly, and a trigger member. The container assembly has a valve assembly. The actuator assembly has an actuator housing defining a rail portion, a trigger member pivotably attached to the actuator housing, and an outlet assembly defining an outlet opening. The outlet assembly is slidably supported relative to the actuator housing by the rail portion. The trigger member engages the outlet assembly such that application of deliberate manual force on the trigger member causes pivoting movement of the trigger member relative to the actuator housing and such that pivoting movement of the trigger member relative to the actuator housing causes linear movement of the outlet assembly relative to the actuator housing. The outlet assembly engages the valve assembly such that linear movement of the outlet assembly alters the valve assembly from a closed configuration to a fully open configuration.
