1. An apparatus comprising:
(a) an end effector including:
(i) a first jaw, and
(ii) a second jaw, wherein the first and second jaws define a gap distance therebetween and are configured to transition from an open state to a closed state to clamp and staple tissue with a plurality of staples;
(b) a trigger configured to be actuated by a user;
(c) a movable member configured to inhibit actuation of the trigger when the gap distance is greater than a predefined gap distance, wherein the movable member is configured to permit actuation of the trigger when the gap distance is less than the predefined gap distance; and
(d) an indicator member configured to provide a visual indication of the gap distance,
wherein the movable member is configured to drive the indicator member in a first direction in response to actuation of the end effector from the open state toward the closed state,
wherein the indicator member is resiliently biased in a second direction opposite the first direction.
