Did a match recently that had 100 yard slug shots on an 18" x 26" steel plate. 9 shots, 3 positions, and a 60 second time limt. The guys with Dots did fine. The of the guys with bead sights (12 on my squad), the only 2 that hit all 9 shots wee the guys with front and rear sights. 1 had the one you posted, and the other had a 930 SPX with the shost ring sights. You don't see them much on huntin shotguns, but 3gun shotguns have them much more often.
