The XS Sights DXW2 Big Dot Sight (part no. GL-0011P-3N) is built for the Glock 42, 43, 43X, and 48, replacing the factory three-dot sights with a single, high-visibility orange Big Dot front. The DXW2 rear is a low-profile V design with a non-tritium white stripe, keeping the sight picture simple and fast 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.

Frequently Asked Questions

Is this the tritium or non-tritium rear version? The rear on this DXW2 set is non-tritium, using a white stripe; the front Big Dot is tritium-powered.

Will this work with my Glock 43X holster? Yes, it is built to fit standard holster options sized for factory Glock sight heights.

Why choose the Big Dot over XS’s Standard Dot sight? The Big Dot’s larger 0.188 in. front is built for the fastest possible acquisition up close, while the Standard Dot’s smaller 0.140 in. front trades some speed for a bit more precision.
