A fastener-driving tool (10) equipped with a fastener magazine, and a power source including a reciprocating driver blade for driving fasteners obtained from the magazine into a workpiece, and a reciprocating valve sleeve actuated by a cage (18) ) is provided with a nosepiece (40) including a nosepiece body (42) configured for attachment at one end to the fastener tool and defining a fastener channel constructed and arranged for receiving the driver blade and the fasteners sequentially fed by the magazine, the fastener channel having a fastener outlet (46). A tubular pin guide (56) is disposed for reciprocal movement in the fastener channel for receiving fasteners traveling toward the outlet. A unitary actuator (84) has a first end (88) engaging the pin guide for common reciprocation relative to the nosepiece body and a second end (90) engaging the cage, and a recessed guide slot defined solely by an inner surface of the actuator and extending along a longitudinal axis of the actuator.
