HD XR Series – Thinner Front Sight, Sharper Sight Picture
The HD XR line is an evolution of the classic Trijicon HD sights, optimized for shooters who want speed and precision:
Slimmer front sight blade compared to standard HD models gives you more visible light on either side of the front post when looking through the rear notch.
This extra light gap makes it faster to center the front sight and offers a cleaner sight picture at distance, ideal for both close-range defense and longer shots.
The U-notch rear and high-contrast front work together to guide the eye naturally to the front sight.
If you like the bold, fast nature of HD sights but also demand tighter shot placement at extended ranges, the HD XR profile is made for you.
Green Tritium with Yellow Front Outline – Day & Night Visibility
These Trijicon HD XR sights are engineered to be highly visible 24/7:
In daylight, the front sight’s bright yellow ring stands out sharply against most backgrounds, drawing your vision immediately to the front sight.
In low light or no light, the green tritium lamps in both front and rear glow with a steady, battery-free illumination so you can index your sights even when you can’t see your target clearly.
The rear lamps are housed in a black outline, making them less visually dominant than the front sight, helping keep your focus where it belongs.
The green/yellow combo is one of the most popular among serious shooters because it remains easy to see under stress, indoors, outdoors, and in transitional light.
Built for Hard Use – Trijicon Quality & Durability
Trijicon is known for building sights that survive real-world duty conditions, and the HD XR night sights are no exception:
Steel sight bodies are designed to withstand recoil, impacts, and harsh environments.
Tritium vials are encased in aluminum and protected by rugged sight housings.
Dot alignment and sight geometry are engineered for long-term consistency shot after shot.
Whether you’re carrying your Sig on duty, off duty, for home defense, or serious range work, these sights are built to last.
Enhanced Front Sight Focus – Designed for Defensive Shooting
The HD XR system is optimized around fast, front-sight-focused shooting, which is critical in defensive scenarios:
The yellow front ring and slim front blade help your eye immediately lock onto the front sight as you present the pistol.
The U-shaped rear notch is wide enough to allow for rapid alignment without feeling cramped or overly precise.
Subdued rear dots mean it’s easy to differentiate front from rear, even when your adrenaline is pumping.
This design helps you make fast, accurate hits at realistic defensive distances, while still supporting more precise shots when you have time to refine your sight picture.
Perfect Upgrade for Sig P225, P226 & P228 Owners
If you own a Sig Sauer P225, P226, or P228, these HD XR sights are a top-tier upgrade over standard factory sights:
#8 front and #8 rear heights are a common factory spec on many Sig classic P-series models (always confirm for your exact pistol).
The steel dovetail design allows professional install using a sight pusher or competent gunsmith.
Once installed, you’ll experience faster target transitions, better low-light performance, and improved sight clarity.
For a defensive pistol that you may rely on in the worst-case scenario, upgrading to Trijicon HD XR night sights is one of the most impactful improvements you can make.
No Batteries, Always On – Tritium Night Sights
Trijicon’s tritium night sights offer the advantage of being self-luminous:
No batteries to replace and no switches to operate.
Sights are always “on,” glowing softly in darkness for years.
Ideal for home defense guns that might sit in a safe or quick-access lockbox until needed—you’ll still have glowing sights when you grab the gun.
Trijicon typically backs their tritium lamps with a lengthy warranty on illumination, reflecting their confidence in long-term performance (check current warranty details with Trijicon).
Ideal Applications – Who These Sights Are For
The Trijicon HD XR Night Sights 600865 are an excellent choice for:
Concealed carriers running a Sig P226, P228, or P225 for personal defense.
Law enforcement or security professionals who need reliable, high-visibility sights for duty pistols.
Home-defense pistols where quick sight acquisition in low light is critical.
Serious range shooters and instructors wanting improved visibility and precision over standard iron sights.
If your Sig is more than just a range toy—if it’s your go-to defensive handgun—these sights are built for you.
Installation & Compatibility Notes
Professional installation using a sight pusher tool or a qualified gunsmith is strongly recommended to avoid damaging the sights or slide.
Verify your Sig model and front/rear height requirements (#8 front / #8 rear) to ensure correct POI/POA alignment.
After installation, always confirm zero at your preferred distance with your chosen defensive or duty ammunition.
