XS Sights DXW2 Big Dot Tritium Night Sight Set for Glock 42, 43, 43X, 48 - White Stripe Rear$109.99
Availability: In Stock
The XS Sights DXW2 Big Dot tritium night sight set for Glock 17-36 models pairs aggressive low-light performance with a wide, forgiving sight picture that works equally well in daylight and darkness. Tritium-powered front and rear sights glow on demand in complete darkness, making these night sights a solid choice for defensive carry, home protection, and low-light shooting scenarios where speed matters more than precision distance work.
The front sight's oversized 0.188" Big Dot design is built for rapid target acquisition and intuitive aiming—drop the dot on target and press. High-contrast coloring makes the front sight visible in bright sunlight, while the tritium element takes over when ambient light fades. The low-profile V-notch rear sight keeps the front sight in your sight picture without distraction, and its white stripe provides a subtle reference line for alignment. The rear sight doesn't contain tritium, keeping cost and profile in check while the bright front sight remains your reference point in low light.
Built from CNC-machined steel and engineered for durability, the DXW2 set includes a ledge on the rear sight designed to facilitate one-handed slide manipulations—useful if you need to chamber a round with a single hand. These sights are made to fit standard Glock holster configurations, so your existing gear stays compatible. If you're running a Glock 17, 19, 22, 23, 26, 27, 33, 34, 35, or 36, this night sight set will drop directly onto your slide.

Tritium is a self-luminous isotope that glows continuously without requiring external light—no charging needed. The glow is always on, but it's most visible in darkness or low-light conditions. Tritium has a half-life of approximately 12.3 years, meaning brightness decreases gradually over time but remains functional well beyond the typical service life of a defensive firearm.
Yes, the XS Sights DXW2 set is appropriate for defensive carry and duty use. These sights are designed to fit standard Glock holster configurations, so your existing holsters should remain compatible without modification.
The set includes a front sight (tritium Big Dot with high-contrast coloring) and a rear sight (low-profile V-notch with white stripe). Installation requires basic gunsmithing tools or professional installation.
