All, A thin blade, regardless of color/material doesn't work well for me. In fact I sold 2 Swiss K-31's because I really couldn't see the thin front sight blade. My BP guns, except for my trade gun, have square notched rear sights and Patridge style front sight blades (flat black), which provide the contrast (and width) that I need. At 25 - 50 yd., I hold with the top of the front sight even with the top of the rear sight (trade gun excepted of course).
