I prefer open V rear sights to ghost ring apertures, because I find that with wide ghost apertures, under pressure it is likely that the rear sight may not be used at all, and wild misses can result. I no longer trust them myself. Ghost ring sights are a good idea in theory. In my case open express sights, a wide shallow V, or a straight bar, beats them for a working sight every time, simply because of this. Peep sights are good target sights.
Very informative post. Put me in this camp as well. I read JOC and Whelen and forced myself to use aperture sights 'cause they were better. Then I finally quit rebuking my own personnel results which indicated I shot better with slight notch or express sights. I might have to try the flat express rear.
