A surgical instrument, comprising: a handle assembly, including: a housing; a trigger pivotably coupled to the housing; and a drive bar slidably disposed within the housing, the trigger pivotable relative to the housing through a full actuation stroke from a first un-actuated position of the trigger to an actuated position of the trigger to translate the drive bar through the housing through a full drive distance ("D1") from a first un-actuated position of the drive bar to an actuated position of the drive bar, the drive bar including a magnetic distal end portion; and an elongated assembly configured to releasably engage the handle assembly, the elongated assembly including: a proximal hub; an elongated shaft extending distally from the proximal hub; an end effector assembly supported at a distal end portion of the elongated shaft; and an inner drive assembly operably coupled to the end effector assembly such that translation of the inner drive assembly actuates the end effector assembly, the inner drive assembly including a magnetic proximal end portion, characterized in that, upon engagement of the elongated assembly with the handle assembly, the magnetic proximal end portion of the inner drive assembly attracts the magnetic distal end portion of the drive bar to pull the drive bar to a second un-actuated position of the drive bar and pivot the trigger to a second un-actuated position of the trigger such that the trigger is pivotable relative to the housing through a reduced actuation stroke ("D2") from the second un-actuated position of the trigger to the actuated position of the trigger to translate the drive bar through the housing through a reduced drive distance from the second un-actuated position of the drive bar to the actuated position of the drive bar. a handle assembly, including: a housing; a trigger pivotably coupled to the housing; and a drive bar slidably disposed within the housing, the trigger pivotable relative to the housing through a full actuation stroke from a first un-actuated position of the trigger to an actuated position of the trigger to translate the drive bar through the housing through a full drive distance ("D1") from a first un-actuated position of the drive bar to an actuated position of the drive bar, the drive bar including a magnetic distal end portion; and a housing; a trigger pivotably coupled to the housing; and a drive bar slidably disposed within the housing, the trigger pivotable relative to the housing through a full actuation stroke from a first un-actuated position of the trigger to an actuated position of the trigger to translate the drive bar through the housing through a full drive distance ("D1") from a first un-actuated position of the drive bar to an actuated position of the drive bar, the drive bar including a magnetic distal end portion; and an elongated assembly configured to releasably engage the handle assembly, the elongated assembly including: a proximal hub; an elongated shaft extending distally from the proximal hub; an end effector assembly supported at a distal end portion of the elongated shaft; and an inner drive assembly operably coupled to the end effector assembly such that translation of the inner drive assembly actuates the end effector assembly, the inner drive assembly including a magnetic proximal end portion, a proximal hub; an elongated shaft extending distally from the proximal hub; an end effector assembly supported at a distal end portion of the elongated shaft; and an inner drive assembly operably coupled to the end effector assembly such that translation of the inner drive assembly actuates the end effector assembly, the inner drive assembly including a magnetic proximal end portion, characterized in that, upon engagement of the elongated assembly with the handle assembly, the magnetic proximal end portion of the inner drive assembly attracts the magnetic distal end portion of the drive bar to pull the drive bar to a second un-actuated position of the drive bar and pivot the trigger to a second un-actuated position of the trigger such that the trigger is pivotable relative to the housing through a reduced actuation stroke ("D2") from the second un-actuated position of the trigger to the actuated position of the trigger to translate the drive bar through the housing through a reduced drive distance from the second un-actuated position of the drive bar to the actuated position of the drive bar.
