An applicator instrument having a reconfigurable handle for dispensing surgical fasteners includes a housing having a proximal end and a distal end, an elongated shaft extending from the housing, a handle coupled with the proximal end of the housing, and a trigger coupled with the handle. The applicator instrument has a firing system including an energy storing assembly that is disposed within the housing, and a gear train disposed within the handle and coupled with the trigger. The trigger is squeezed for commencing a firing cycle and storing energy in the energy storing assembly. The applicator instrument includes a handle reconfiguration actuator having a first position for locking the handle in place relative to the housing and a second position for enabling the handle to rotate relative to the housing between a pistol configuration and an in-line configuration. The applicator instrument dispenses surgical fasteners with the handle in the pistol configuration, the in-line configuration, and at angles located between the pistol and in-line configurations.
