A surgical stapler comprising: (a) a body; (b) a shaft assembly extending distally from the body; (c) an end effector at a distal end of the shaft assembly, wherein the end effector is actuatable between an open state for receiving tissue and a closed state for clamping the tissue, wherein the end effector is configured to receive a staple cartridge having staples; (d) a closure system operatively coupled with the end effector, wherein the closure system is operable to actuate the end effector from the open state to the closed state; (e) a firing system operatively coupled with the end effector, wherein the firing system is actuatable to fire the end effector and thereby staple and cut the clamped tissue; and (f) a lockout member operatively coupled with the closure system and the firing system, wherein the lockout member is configured to inhibit actuation of the closure system to prevent closure of the end effector when an unspent staple cartridge is absent from the end effector, wherein the lockout member is further configured to inhibit actuation of the firing system to prevent repeated firing of the end effector with the same staple cartridge, wherein the lockout member includes: (i) a first lockout feature operable to inhibit actuation of the closure system to prevent closure of the end effector when an unspent staple cartridge is absent from the end effector, and (ii) a second lockout feature operable to inhibit actuation of the firing system to prevent repeated firing of the end effector with the same staple cartridge, characterized in that: the first and second lockout features are spaced apart longitudinally along a longitudinal axis of the shaft assembly.
