A surgical instrument for surgically joining a tissue includes a handle assembly, an elongate portion extending distally from the handle assembly, a pair of opposed jaw members, and a tissue stop. The tissue stop is mechanically engaged with a first jaw member and is configured to retain the tissue between the jaw members. The tissue stop is movable between a first position, where a stopping portion of the tissue stop is disposed between a tissue-contacting surface of the first jaw member and a tissue-contacting surface of the second jaw member, and a second position, where the stopping portion is between the tissue-contacting surface of the first jaw member and a lower surface of the first jaw member. A portion of the tissue stop is made of stamped metal section and a portion of the tissue stop is made of an overmolded plastic section.
