1. A surgical stapling instrument comprising:
(a) a shaft extending along a longitudinal axis to a distal end; and
(b) an end effector operatively coupled with the shaft, wherein the end effector includes:
(i) a first jaw including:
(A) an anvil,
(B) at least one trunnion, and
(C) at least one first abutment surface, and
(ii) a second jaw configured to cooperate with the first jaw to clamp tissue, wherein the second jaw is configured to support a stapling assembly, wherein the second jaw includes:
(A) at least one locking notch configured to receive the at least one trunnion, and
(B) at least one second abutment surface configured to engage the at least one first abutment surface when the at least one trunnion is received within the at least one locking notch to thereby prevent closure of the first jaw toward the second jaw.
