Brianma,
Do you have perfect eyesight? I have poor close range vision so I need corrective lenses to actually pick up my sights. Real pain with scopes too! My handgun sights are always fuzzy regardless of what kind I have. I'm always looking for something I can see clearly without corrective lenses.
I don't even know if the ones I'm thinking about exist for the M&P but the undercut front sights like the older S&W target sights on the K frame revolvers are really good for target shooting as the undercut on the sight deflects light so the front sight is very clear. They don't make a good choice for holster use as they may snag leather during the draw, Kydex, not so much.
If your M&P is only for target use and you want the blacked out front sight, see if anyone here has info on the undercut ones ( maybe S&W themselves can help?) Good luck Brian!
