Yes, a nice express-style rear would be nice. I'd even take one that was fixed and tweak it to my load, finally re-bluing it when I got it just right.

I wonder if the dovetail in the Ruger quarter rib could be opened up to accept a NECG two or thee blade sights that they offer. A guy could get the 2 blade unfinished and file it to the proper height if the dovetail could be opened up to the proper size.
