40SKS. changing pin box = Morryde May 1, 2021 10:18:17 GMT -5 Quote Select PostDeselect PostLink to PostBack to Top Post by captjack on May 1, 2021 10:18:17 GMT -5 Has anyone swapped out the med 7910 Morryde with a 7920 long pin box ?? Even with a Demco auto slide im really tight. The 7920 puts the pin 9 inches further out.
