The XS Sights DXT2 Big Dot Sight (part no. SW0029S5Y) fits the full-size and compact Smith & Wesson M&P and swaps the standard three-dot sight picture for a single, unmistakable yellow Big Dot front. That is a deliberate trade: it is built for fast, close-range defensive shooting rather than precision work, and the tritium-center rear notch keeps a measure of night capability without cluttering the sight picture.

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 (white outline with a tritium center) 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.
• Fits standard holster options built around factory sight heights.
