The AmeriGlo CAP Sight Set for Glock 20-41 Gen 1-4 is a self-illuminated pistol sight upgrade designed for shooters who need fast, reliable sight acquisition in variable lighting. The CAP system pairs a tritium-powered front sight with a photoluminescent rear, giving you a sight picture that's visible in low light without batteries, electronics, or external power sources. This is purpose-built for defensive shooters, competitive handgunners, and anyone who carries a full-size or compact Glock and wants sights that work when it matters.
The front sight features a bright green tritium insert—manufactured by Trijicon and installed by AmeriGlo—surrounded by a large photoluminescent outline that glows in daylight and fades gracefully as light dims. The rear sight is plain black with a photoluminescent horizontal line, designed to let the bright front sight dominate your sight picture while keeping alignment fast and intuitive. Both sights are finished in black nitride, a durable and corrosion-resistant coating that holds up to regular carry and use.
The square front sight profile and standard-height geometry mean you're not sacrificing accuracy for speed—these sights maintain the proven Glock sight pattern that works for both aimed fire and rapid target engagements. Tritium sights don't require charging or maintenance; they simply work, day or night, for years. For Glock 20-41 shooters in Gen 1 through Gen 4 frames, this sight set closes the gap between factory plastic and premium night-capable optics.
