The XS Sights DXW2 Big Dot Sight (part no. SW-0030S-3Y) is sized for the Smith & Wesson M&P Shield and trades the factory three-dot sights for a single, fast-acquiring yellow Big Dot front. Its DXW2 rear uses a non-tritium white stripe in a low-profile V design, keeping the sight picture simple for close-range defensive shooting.

Key Specifications

• Front sight is tritium-powered for round-the-clock illumination.
• Big Dot front measures approximately 0.188 in. in outside diameter for a fast, unmistakable aim point.
• Uses a high-contrast colored front sight paired with a Glow Dot design that absorbs ambient light and glows in low light.
• Rear sight is a low-profile V design (non-tritium white stripe) that improves visibility of the front sight instead of competing with it.
• Follows XS’s dot-the-i sight picture, a straight-line alignment that is hard to confuse front from rear.
• Rear sight ledge allows one-handed slide manipulation against a belt or holster edge.
• Rear and front are durable CNC machined steel, not cast or stamped.
• Backed by a 10-year warranty and a 30-day satisfaction guarantee from XS Sights.
