I have gotten very used to the sight picture on my HK P2000. It seems to have a bigger sight picture or ratio than typically speced on American guns. The front blade is .140" wide and the rear notch is .170" wide. The M&P which comes with a .130" ft and a .140" rear notch. What width front and rear combo would I need to gain the extra light in the sight picture that I am used to?
