There is a difference between rifle sights and express sights. I have a pedestal bead on my 870 and express sights on my Beretta 1201. I tried rifle sights on an 870 and didn't like them much. The Beretta came with them and I found the same thing. Ashley Emerson was playing around with the idea of putting his Express Sights on a shotgun, and I got to be the test subject for the first set. I like the express quite a bit, and find it to be a good compromise between speed up close and accuracy at distance.
