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.
