Don't forget to pick up a filler blank for the rear sight dovetail slot, after you remove the rear sight for a clean sight picture.
AND, I'd pick up a FireSight front sight blade, too - Williams makes/sells both the FP & the 5D as a kit with the proper height front FireSight.

Heck, if you have to have a front sight hood, Williams even makes one with a hole in it's roof, especially for FireSights.
