Hello all, I just got my first Mossberg, a 590A1 with 3 dot sights. My question is does anyone make tritium sights for this setup. The front blade sight is mounted in a dovetailed slot with a set screw holding it in place, the rear is held in place on top of the barrel by a screw. Exchanging them is a no-brainer if I could just find tritium replacements. I did a search and found nothing for the 3 dot sights. Has anyone seen this?
