Yup, Drilling Man, that's the other alternative. My reasoning for replacing the front sight was that even as a shotgun, without using the rear sight (folded flush) and sighting down the top rib, with the tall blade on the gun, the shot pattern shoots low, and the front blade is kind of in the way. I thought that by installing a small bead on the front, instead of that tallish blade, it would bring the pattern up. The bonus would be that by aligning a small bead level with the rear sight, it would bring the point of aim up for shooting slugs. A taller rear sight blade would work for shooting slugs, but would not help shot patterns shoot higher, because as a shotgun, the rear sight would be folded down. Also, a taller rear blade would not allow the rear blade to fold all the way flush with the rib in the sight recess. Shotgun front beads can be purchased in large to small diameters, and tall to low heights, and in a variety of colors from plain metal to high viz fiber optics. Seemed to be the simplest solution, if I could just find a front lengthwise dovetail sight that would fit the slot on that gun. This way, I could have the blade ground off, and have it tapped for a bead sight, and thus not risk messing up the original sight that came with the gun.
