The XS Sights DXT2 Big Dot Night Sight Set (brand part no. SW-0036P-5Y) pairs a green tritium, yellow-outline front sight with a green tritium, white-outline bar rear sight, built to drop onto compatible Smith & Wesson pistols. XS Sights engineered the front sight with a proprietary photoluminescent Glow Dot that absorbs ambient light and glows in low light, and the dot’s convex shape adds surface area to intensify that charge. The big, highly visible dot-the-i sight picture — a tritium dot up front and a tritium bar in the rear — helps prevent confusing the front and rear sight in a high-stress situation, while the shallow-V rear notch keeps a wide field of view.

Frequently Asked Questions

What pistols does this sight set fit? Compatible Smith & Wesson models.

Why is the front sight a big dot? XS designed it large and highly visible to help with aging eyes and deteriorating vision, and for a faster sight picture under stress.

How does the sight picture prevent confusion? The dot-the-i design puts a tritium dot up front and a tritium bar in the rear, so the two are never mistaken for each other.
