Key Specifications

• Rear notch is wide, with serrations and an anti-reflective lens to cut glare.
• Corrosion-resistant Black Nitride surface finish on both sights.
• Traditional 3-dot tritium notch-and-post sight picture.
• Front sight glows green; rear glows black-outlined for a clear contrast pair.
• Suppressor height puts the sights in the co-witness window of most Glock-footprint red dots.
• Cut for a Glock 42, 43, 43X, or 48 (Gen 1-5, including MOS).
• Proudly manufactured in Fort Worth, Texas.
• Compatible with Glock Gen 1-5 pistols, including MOS-milled slides.
