Product Description

XS Sights DXT2 PRO Series Big Dot Night Sights deliver exceptional front sight visibility with a rugged Black Nitride finish and upgraded tritium lamps. The large green Big Dot front sight features a convex photoluminescent glow dot that charges in light and glows in low-light conditions before the tritium becomes visible. Paired with a low-profile V‑notch rear that uses a tritium vertical bar, the simple dot‑the‑“i” sight picture speeds alignment and helps prevent confusion between front and rear sights under stress. CNC‑machined steel construction and an aluminum‑sleeved tritium insert add durability. Fits Glock models 20, 21, 40, and 41 (standard and MOS). Installation note: do not use a sight press/pusher tool.
