1. A stapling system, comprising:

  • an anvil comprising an anvil ledge;

    a channel comprising a channel ledge;

    a firing bar comprising a first projection configured to engage said anvil ledge and a second projection configured to engage said channel ledge;

    a replaceable staple cartridge, comprising;

    a proximal end positionable adjacent said firing bar;

    a distal end positioned opposite said proximal end;


    a vertical slot extending longitudinally from said proximal end toward said distal end, wherein said vertical slot is configured to receive said firing bar during a staple firing stroke; and

    a sled spanning across said vertical slot, wherein said sled is movable between a proximal unfired position and a distal fired position; and

    a locking member movable vertically and spring-biased into a locked configuration which inhibits said firing bar from being advanced through said staple firing stroke, wherein said sled comprises a proximally-extending portion configured to overcome the spring bias of said locking member if said sled is in its proximal unfired position.
