Why Choose Rival Arms Tritium 3-Dot Sights
Whether you carry daily, train after dark, or want a reliable back-up sighting system for defensive scenarios, the Rival Arms RA-RA2B231G delivers. The green tritium provides a bright, easy-to-find aiming point when ambient light fades, while the white front ring increases speed in daylight. Combined with a tough QPQ finish and precision dovetail fit, these sights are a high-value upgrade for compact Glock owners seeking improved accuracy and confidence across lighting conditions.
Compatibility & Fitment
Fits: Glock 42 and Glock 43 (check your slide model and any factory/aftermarket cuts).
Dovetail: Designed for standard Glock front/rear dovetails—verify existing sight dovetail size and orientation before purchase.
Optic Use: Low-profile rear is sight-picture friendly with many red-dot optics, but if your slide is optic-cut or you use suppressor-height optics, confirm co-witness/visibility beforehand.
Installation & Setup
Drop-in replacement: These sights are manufactured to replace factory Glock sights using the standard dovetail.
Recommended installation: For best accuracy, pinion timing, and dovetail integrity, have sights installed and drifted by an experienced gunsmith or armorer using proper sight-pusher tools. Improper installation may damage the slide or sight.
Timing & drift: When installing, the front sight should be centered and the rear timed for desired windage—small adjustments should be done with precision tools and verified on target.
Materials & Finish Details
Body Material: Hardened steel for impact resistance and long service life.
Finish: Black Nitride QPQ — a thermochemical treatment that improves corrosion resistance, reduces friction, and extends wear life compared to untreated or basic blued parts.
Tritium Vials: Sealed, self-luminous tritium cells rated to provide reliable low-light glow for years (tritium output gradually decreases over long service life — typical industry lifespan is many years).
Care & Maintenance
Cleaning: Wipe with a soft cloth after range use; remove solvents or copper fouling from nearby areas but avoid soaking tritium vials.
Inspection: Periodically check that sights remain securely seated in the dovetail; confirm no cracks around the vial housing.
Avoid rough hammering: Use proper sight tools; avoid heavy impact that could damage the vial or sight body.
Service life: Tritium brightness diminishes slowly over time; if reduced night visibility becomes an issue, replacement sight sets are available.
Practical Use Cases
Everyday Carry (EDC): Fast, reliable sight acquisition in low light for concealed-carry Glock 42/43 owners.
Home Defense: Improved sight visibility for low-light home scenarios without relying on weapon-mounted illumination.
Night Training & Duty: Useful for instructors, off-duty officers, and private citizens who train or operate in varied light conditions.
Backup/Redundancy: Solid mechanical sights that provide a dependable back-up to optics or electronic aiming systems.
