Upgrade your defensive Glock with XS Sights R3D Night Sights—a fast-acquisition, duty-tough sight system built to deliver daylight speed and low-light confidence. The high-visibility green front tritium dot grabs your eye instantly, while the crisp, anti-glare rear notch drives a clean sight picture in bright sun, dim hallways, and everything in between. Machined from hardened steel with a durable blued finish, these R3D sights are engineered for everyday carry, home defense, and agency duty pistols that must perform on demand.
Whether you’re running a Glock 20/21 for powerful hunting sidearm duty, a compact 29/30/30S for concealed carry, or a long-slide 41 for competition and field work, the XS R3D system gives you fast, intuitive alignment and reliable glow when light is scarce.
Why Choose XS Sights R3D for Your Glock
Lightning-Fast Front Sight Focus
The green tritium front dot with a photoluminescent (glow-in-the-dark) ring is designed to pull your focus forward, speeding up front-sight acquisition in both daylight and dusk.
Purpose-Built Rear Sight
A black, anti-glare rear with a wide U-/square-notch frames the front dot for quick centering. (Many R3D models include twin tritium lamps in the rear for balanced low-light alignment.)
True Night Performance
Tru-grade tritium vials provide a persistent glow—no batteries, no buttons—so your sights remain visible after your weapon light turns off or your eyes adjust.
Carry-Proof Construction
Solid steel, blued bodies resist hard use, holster wear, and slide manipulations. The rear ledge supports one-handed racking off a belt or barricade in emergencies.
Clean, Consistent POA/POI
Built to factory height for most Glock sight pictures, maintaining a familiar zero with defensive loads (always confirm on your pistol).
Proven XS Quality
Designed for EDC and duty reliability, with long-life tritium and rugged steel built to withstand high round counts.

Performance You’ll Notice
Faster Sight Picture Under Stress
The eye is naturally drawn to bright green—pair that with a bold front ring and you’ll find the front sight faster, especially from the holster or low ready.
Reliable Low-Light Index
When the lights go down, tritium vials in the front (and in many R3D rears) give you a clear, three-dot alignment that doesn’t rely on batteries or ambient charging.
Durable, Daily-Carry Ready
Steel construction, precise machining, and a protective blued finish stand up to sweat, weather, and holster wear—ideal for concealed carry and duty rigs.
What’s in the Box
XS Sights R3D front sight (green tritium)
XS Sights R3D rear sight (anti-glare notch)
Mounting hardware/instructions (varies by package)
We recommend a Glock front sight tool and a quality sight pusher (or gunsmith install). Use non-permanent thread locker on the front-sight screw; confirm windage/height at the range.
Installation & Zero Tips
Unload & Clear: Verify the firearm is unloaded—remove mag, lock slide, and visually/physically inspect.
Remove Factory Sights: Use a Glock front-sight nut driver and a sight pusher for the rear.
Install New Sights: Degrease contact points; apply a small drop of thread locker to the front screw; press-fit the rear centered in the dovetail.
Confirm Zero: Fire from a stable rest at 10–15 yards with your defensive ammo, adjust windage as needed, and re-check fast strings.
Ideal Use Cases
Concealed Carry & Home Defense – Immediate front-dot focus and reliable glow when lighting is inconsistent.
Duty & Training Pistols – Steel durability, ledge for one-hand slide work, and high-visibility dot for faster quals.
Field/Hunting Sidearms – Clear, battery-free sighting at dawn/dusk with heavy-duty construction.
Frequently Asked Questions
Q: Will these co-witness with my red dot?
A: R3D sights are standard height. For co-witness, choose suppressor-height versions matched to your optic.
Q: Do I need a gunsmith?
A: Many shooters install at home with the correct tools, but a professional install ensures proper fit, centering, and thread-locker application.
Q: How long does the tritium glow last?
A: Tritium has a multi-year half-life and provides long-term low-light visibility; XS backs their tritium with a manufacturer warranty.
Q: Green vs. Orange/Other Colors?
A: Green is typically the brightest to the human eye, which helps the front sight stand out fastest during stress or motion.
Q: Will these fit my Glock 30S specifically?
A: Yes—Glock 30S is covered in this GL-R013P-6G fit set along with Glock 20/21/29/30/37/41.
