I vote for the williams FP. Though an older, all steel Lyman or Redfield would be a score! My personal preference for front sight is Skinners front blade. I like this front sight because it is sturdy, well made, easy to file down to the right hight (I order mine tall) and I prefer a post or blade front sight to a bead, when using an aperture rear sight. I bet the fire sights work well, but have not tried them, partly because I just like the traditional look of a good blade (patridge?) sight. One day I would like to try a tang mounted aperture sight.
