The XS Sights DXT2 Big Dot Sight (part no. SW-0030S-5N) is sized specifically for the Smith & Wesson M&P Shield and replaces its factory three-dot sights with a single, high-visibility orange Big Dot front built for fast, close-range defensive shooting. The rear notch carries a white outline around its own tritium center, giving the Shield genuine night capability without a busy 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.

Frequently Asked Questions

Does this fit the Shield EZ? No, this DXT2 set is sized for the standard M&P Shield dovetail, not the EZ.

Is the Big Dot front tritium? Yes, the front is tritium-powered for round-the-clock illumination, not just a painted or fiber-optic dot.

How is this different from a standard three-dot sight? It replaces the smaller equal-size dots with one large, fast-acquiring front dot, trading some precision for speed in a defensive shooting.
