I bought XS Big Dots for my Glock G20 back in the 90s because I fully bought into the idea of having a large front aiming dot for fast sight acquisition. The V-shaped rear, however, is what killed the experience for me. As fast as the Big Dots were for me up close, I never adapted to the sight picture for carefully aimed shots.
XS Sights heard my pleas, introducing their own “figure eight” sights with a very big-dot-like front sight sitting in a conventional square notch rear. This gives much of the fast acquisition of the original Big Dot with a conventional sight picture for carefully aimed shots. A smaller rear tritium dot provides alignment in low light.
