The staple cartridge comprises a longitudinal slot and three longitudinal rows of staple cavities defined alongside the longitudinal slot with staples removably stored therein. A double staple driver supports one staple from the first row and one staple from the second row. A single staple driver supports one staple from the third row. A sled comprises a first camming surface configured to contact the double driver, a second camming surface configured to contact the single driver, and a central portion movable through the longitudinal slot during a staple firing stroke. The first camming surface comprises a first width, and the central portion comprises a third width. The third width is greater than the first width. The firing member translates into a lockout recess when the sled is not in a proximal position prior to performing the staple firing stroke.
