I run Heinie Straight 8’s with the ledge rear on most of my pistols. I use the ledge since I run them in a duty capacity and can use the rear sight to rack the slide if need be. They are by far the fastest sights for me. The only pistol I have that is different (that I carry regularly) is my G26 which has Hackathorn sights on it because I had them laying around and it was easier than spending another $140 on Heinie’s.
