AmeriGlo CAP Operator Sight Set for Glock 17/19
The AmeriGlo CAP (Combat Application Pistol) Sight Set for Glock 17/19 delivers a proven rapid-acquisition sighting system trusted by law enforcement and competitive shooters alike, combining tritium illumination with bold orange reference points for fast, confident target engagement in any lighting condition.
- Green tritium front sight glows in low-light without batteries or activation
- Square orange outline on front post accelerates eye-to-sight alignment under stress
- Flat black rear sight with .155" wide square notch reduces visual clutter downrange
- Horizontal orange paint strip under rear notch reinforces correct sight picture instantly
- .140" wide front post paired for precise point-of-impact at 15 yards (A-Box method)
- Designed specifically for Glock 17 and Glock 19 factory dovetail cuts — no gunsmithing required
Who This Is For
The AmeriGlo CAP Sight Set is built for Glock 17 and 19 owners who demand faster sight acquisition than standard factory sights allow — whether for concealed carry, home defense, or duty use. The high-contrast orange and tritium combination benefits shooters who train in varied lighting environments, and the intuitive "front-in-the-box" alignment method is especially valuable for those who prioritize speed without sacrificing accuracy at practical self-defense distances.

Frequently Asked Questions
What does the "A-Box" aiming method mean, and how does it work?
The A-Box method means your point of impact is the center of an imaginary box formed by the rear notch — as long as any portion of the front sight is visible within the rear notch opening, you are on target at 15 yards. This technique allows for extremely fast sight alignment under pressure because you don't need a perfectly centered, precise picture to achieve an accurate hit at typical defensive distances.
Will these sights fit my Glock 17 or 19 without modification?
Yes. The AmeriGlo CAP Sight Set is machined to fit the standard factory dovetail cuts on Glock 17 and Glock 19 pistols. Installation requires a standard Glock sight pusher tool or a bench block and punch — no milling, drilling, or permanent modification to your firearm is needed. Always verify your specific generation and variant for fitment before ordering.
How long does the tritium illumination last?
Tritium is a mildly radioactive gas that produces a steady self-luminous glow through a process called radioluminescence — no batteries, charging, or activation required. The tritium vials used in AmeriGlo sights have a half-life of approximately 12 years, meaning they will retain roughly 50% of their original brightness after that period. Most shooters find the glow remains functionally useful for 10–15 years of normal service.
