Agree with the tight pattern remark RR - fully and that is why I strongly recomend a pair of those clamp on True Glo sites. I use the ones that allow for windage and elevation.

Why - with today's chokes and tight patterns you actually are shooting a bird shot slug IMO.
The sights force you to keep your head down, if you have done your homework you know once you put that bead on your aiming spot and the distance is correct - you ain't missin'!
