The HiViz XDN521 LiteWave H3 Tritium/LitePipe XD sight set brings reliable low-light and daylight visibility to Springfield XD, XDS, XDE, and XD-M pistols. This is a front and rear sight pair engineered to work around the clock—fiber optic rods gather ambient light during the day while self-illuminating tritium inserts take over at night, so you get a consistent three-dot sight picture whether you're at the range at noon or on a defensive draw in low light. The front sight features a bright orange ring surrounding the green dot, designed to help you acquire the sight picture fast and confirm proper alignment before breaking the trigger.
Both front and rear dots glow green, following the intuitive horizontal three-dot pattern shooters know instinctively. The sight bodies are steel with a satin black finish, built tough to protect the tritium vials and fiber optic inserts from the abuse of training and carry. This is a drop-in fit to your XD-pattern slide dovetails, so installation is straightforward—no gunsmith required. The sights are sized to clear standard holsters, so you won't have to change your carry setup.
Whether you carry for duty, competition, or personal defense, night sights eliminate the guessing game in low light. The LiteWave H3 design bridges the gap between day and night visibility better than traditional fixed sights alone, and the orange front ring adds a sight picture confirmation layer that speeds target acquisition under pressure.
| Product Name | HiViz XDN521 LiteWave H3 Tritium/LitePipe XD Sight Set |
| Model Number | XDN521 |
| Brand | Hi-Viz |
| Type | Front and rear sight set |
| Front Sight | Green tritium with orange outline ring |
| Rear Sight | Green fiber optic |
| Material | Steel |
| Finish | Satin black |
| Sight Pattern | Horizontal three-dot |
| Compatibility | Springfield XD, XDS, XDE, XD-M (not XD with 5.25" barrel) |
| Installation | Drop-in fit to factory dovetails |
Yes, the XDN521 set fits Springfield XD, XDS, XDE, and XD-M pistols. The one exception is XD models with a 5.25" barrel, which are not compatible with this sight set.
The sight set combines two technologies. The fiber optic rods in the rear sight and front sight gather ambient light during daylight and twilight hours to create a bright green three-dot picture. At night, the self-illuminating tritium inserts in both the front and rear sights take over, maintaining full visibility of all three dots without any external power source.
The orange ring surrounding the front green dot serves as an acquisition aid, helping you locate and align the front sight with the rear sight faster under pressure. It provides visual confirmation of proper sight alignment before you press the trigger.
The sights are sized to allow proper clearance in standard holsters, so you should not need to change your carry setup. If you use a custom or tight-fitting holster, verify clearance before carry.
