I generally find with SA revolvers the sights are easier to see with adjustable sight guns...
That said I don't think I have even held a fixed sight FA revolver. They do have the optional replaceable dovetailed front sight however so both windage and elevation can be adjusted via the front blade.
I just get a clearer sight picture with the adjustables...

Yep, what this guy said!
Bob needs adjustable sights so he can whack targets on a hill 780 yards (give or take) away. Dang stunt shooter!
