This is AmeriGlo's classic tritium front sight for Glock pistols, built around a green tritium lamp wrapped in a crisp white outline. At .407" tall with a .140" wide blade, it sits on the taller end of AmeriGlo's front-sight lineup, which makes it a go-to choice when you're running a suppressor, a red dot, or just need to dial in your point of impact with a taller post. The steel body is machined for a tight, no-wobble fit, and because tritium is self-powered, the front dot glows on its own whether you're in a pitch-black room or a dim parking garage.
Swapping the factory plastic front post for this AmeriGlo sight is one of the simplest upgrades you can make to a Glock. The green lamp is the easiest tritium color for most eyes to pick up, and the white ring around it gives you a high-contrast reference in daylight so your eye snaps to the front sight the moment you present the gun. It fits all Glock models, so it works across the G17, G19, G34 and the rest of the lineup as a front-only replacement.
Height matters when you start changing the sight picture. That .407" measurement is popular with folks co-witnessing an optic or clearing the taller sight line a suppressor demands, and it's also the number people land on after running a front-sight height calculation to correct where their rounds are landing with an existing rear. If you know you need a tall front, this is the one.
Tritium has a half-life of about 12.3 years, and AmeriGlo backs the green lamp with a solid useful lifespan, so you're looking at roughly a decade-plus of dependable glow before it's time to refresh. Pistol front sights press into a dovetail and stake down, so plan on a proper sight pusher or a trip to your gunsmith rather than a punch and a hammer. Do it right and this sight will ride your slide for years.
Yes. AmeriGlo lists this front sight as fitting all Glock models, so it works across popular pistols like the G17, G19, G26, and G34. It's a front-only sight, so you'll pair it with a compatible Glock rear that matches your setup.
The taller post is a favorite for anyone running a suppressor or co-witnessing a slide-mounted red dot, since it clears the raised sight line those setups create. It's also the height people commonly land on after a front-sight calculation to correct their point of impact. If you have a standard-height slide with no optic or can, a shorter front sight may serve you better.
Tritium has a half-life of about 12.3 years, meaning brightness gradually fades over time rather than switching off. In practical terms you can expect roughly 10 to 12 years of genuinely useful glow before it's worth replacing. Best of all, there are no batteries to worry about since the glow is self-powered.
Glock front sights press into the slide's dovetail and are secured with a screw or stake, so a proper sight pusher tool makes the job clean and repeatable. If you don't have the right equipment, having a gunsmith set it is cheap insurance against a damaged sight or a marred slide. Take your time getting it centered and you'll be good to go.
