1. A reload assembly for a surgical stapling system, the reload assembly comprising:
an elongate shaft having a proximal end and a distal end and defining a longitudinal axis extending between the proximal end and the distal end;
a jaw assembly positioned at the distal end of the elongate shaft, the jaw assembly comprising:
a first jaw comprising a reload support configured to receive a staple reload; and
a second jaw pivotably coupled to the first jaw, the second jaw comprising an anvil surface;
an actuation beam longitudinally slidable within the elongate shaft, the actuation beam having a proximal end and a distal end, the distal end of the actuation beam coupled to the jaw assembly; and
a shaft coupler at the proximal end of the elongate shaft, the shaft coupler comprising a locking member positioned therein, a proximal portion of the locking member radially outwardly advanceable relative to the longitudinal axis by distal actuation of the proximal end of the actuation beam to place the shaft coupler in a locked configuration;
wherein the shaft coupler has an unlocked configuration with the locking member in a radially inward position, the shaft removably positionable in a coupler of a handle assembly in the unlocked configuration; and
wherein with the shaft coupler in the locked configuration and the shaft positioned in the coupler of the handle assembly, the shaft is locked in with respect to the handle assembly.
