I have not tried the Vickers Elite sights, but I do use the all-black Dawson Precision Competition model with the "Hi-Def" rear notch in .145 rear notch width, and the corresponding Trijicon front sight. That setup is the absolute very best I have ever used in my entire 27-year shooting career, using an HK USP for 23 out of those 27 years, and worked much better for me than Novak sights, Heinie Sights, Entreprise sights, or anything else. I recommend these very highly and with great enthusiasm, and they are also in use with many other members on this board, mostly with the fiber optic fronts.Anybody used the Vickers Elite Battlesight on their H&K or any other platforms. . . it's pretty much down to these or the Dawson's.
