Front sights can be tinkered with too.  I have .073" thick blades on mine.  I didn't cut the slot in the sight stud wider, I just thinned the blades at the bottom to fit the slot, so I can go back to standard blades.  My front sights are taller too, for two reasons.  I shoot higher velocity loads, and my rear sight has a V notch.  I level the top of the rear sight with the front sight stud, and leave the blade sticking up where I can see things around it, like the target number!
