Upgrade Your Revolver for Modern Defensive Use
The XS DXW2 Night Sights with Adjustable Rear are purpose-built to give your Smith & Wesson revolver modern visibility, rugged precision, and 24/7 confidence. Whether you're carrying for personal defense, exploring dangerous back country, or just want tighter groups at the range, this sight set is the upgrade your wheel gun deserves.
At the core of the sight system is a tritium powered front sight. It is surrounded by our EMBER technology, a photoluminescent glow dot for maximum contrast in low light and bright conditions. Color options include:
- Orange – Maximum visibility in bright daylight, perfect for outdoor shooting.
- Green – Balanced performance in all lighting conditions, the most versatile option.
- White – Highest contrast for all environments, ideal for indoor and low-light transitions. White is reflective, not photoluminescent.
- Yellow (Match Drilled Only) – Superior glow in low light, best for dark environments.
Pair that front sight with a CNC-machined steel adjustable rear sight, and you’ve got an extremely durable, shooter-tuned platform for accuracy and speed under stress.
Choose Your Front Dot Size: Big or Standard
Big Dot: If your priority is speed and visibility under stress, the XS Big Dot delivers. The oversized front sight pulls your eye in fast, making it ideal for self-defense, close-quarters scenarios, and extreme back country situations. The dot-the-‘i’ sight picture lets you align and fire fast without overthinking it.
Standard Dot: For shooters who want more precision at greater distances, the smaller Standard Dot provides a refined aiming point while still offering the same 24/7 glow and express sight picture. It's a perfect choice for target shooting, hunting, or anyone who prefers a finer sight picture without sacrificing visibility.

Installation Options: Pre-Drilled vs. Match-Drilled
Pre-Drilled: Designed for the confident DIYer, pre-drilled sights are ready to install with basic tools. No drill or mill work needed. Just steady hands, thread locker, possible file, and a clean bench. This is the go-to option for most shooters.
Match-Drilled: For those wanting a factory-tight fit with zero movement, the match-drilled option requires a gunsmith or machinist with access to a drill press or other tools. It’s more time-intensive but offers the most precise front sight installation possible.
Note: Both versions pair with the included CNC-machined adjustable rear sight. Front sight fitment is the only difference.
Installation Instructions
Rear sight installation involves removing the factory windage screw and staking the included replacement nut, which may require a spanner wrench or staking tool.

About XS Sights
The express sight concept started it all for us over 25 years ago. Our founders wanted to engineer a sighting system primed for defensive situations that was big and easy to see. Modeled after African big game hunting sights, express sights are designed to give you a visible, and combat accurate flash sight picture when seconds count. The sights are CNC machined from solid steel bar stock by our in-house machine shop. We design, machine, and insert our tritium to produce the highest quality possible and provide American Made products. We are a small, second-generation family-owned business based in Fort Worth, TX, and our customers are family. We offer easy DIY install instructions. Upgrade today and discover the XS Advantage.
