Description
AmeriGlo built the Trooper line around what they learned from their award-winning U.S. Federal Government contract sights, and this set brings that same duty-grade thinking to SIG Sauer pistols that run a #6 front and #8 rear. It's a traditional three-dot layout that gives you a fast, clean picture whether you're on the range in broad daylight or clearing a dark hallway at 2 a.m.
The magic here is the ProGlo front sight. It's a green tritium lamp wrapped in a bright orange outline, so your eye snaps right to it in daylight and it keeps glowing green after the sun goes down. No batteries, no switches, nothing to charge. The tritium works around the clock on its own.
What the Trooper Sight Set Does on Your SIG
Matched up front is a serrated square-notch rear with two green tritium dots and a subdued black outline. The serrations cut down glare so you're not fighting reflections off the rear face, and the blacked-out notch pulls your focus forward to the orange front dot where it belongs. That front-sight-focused design is exactly what you want for defensive shooting and quick follow-ups. In total darkness you still get the classic three green dots for alignment.
Fitment and Getting the Trooper Sights On
This set fits most SIG Sauer models that use a #6 front and #8 rear dovetail, which covers a big chunk of the P-series lineup. It's a straightforward dovetail swap, though a sight pusher and a little know-how make the job cleaner than a hammer and punch. If you're not comfortable driving sights yourself, any competent gunsmith can knock it out in a few minutes.
Why Tritium Earns Its Keep
Tritium is a proven low-light solution that's been trusted on carry and duty guns for decades. Expect the lamps to stay tactically useful for roughly a decade of real service before they gradually dim, and AmeriGlo backs the tritium accordingly. For a set-it-and-forget-it upgrade that makes your SIG faster to run day or night, the Trooper is tough to beat.

Frequently Asked Questions
Which SIG pistols do the AmeriGlo Trooper sights fit?
This set is cut for most SIG Sauer models that use a #6 height front and a #8 height rear dovetail, which covers a large portion of the P-series lineup. SIG uses several dovetail and height combinations across their pistols, so it's worth confirming your specific model calls for #6 front and #8 rear before ordering. If you're unsure, check your slide's sight spec or ask us and we'll help you match it up.
Do the Trooper night sights need batteries?
No. The green glow comes from self-powered tritium lamps that work on their own, with no batteries, charging, or light exposure required. That means they're always ready in the dark without any input from you.
How long will the tritium stay bright?
Tritium slowly dims over time as it decays, and most sets stay tactically useful for roughly a decade of real service before the glow drops off noticeably. You'll still see them in a dark room past that point, but they won't grab your eye as fast in transitional light. AmeriGlo backs the tritium accordingly, so a mid-life set will still serve you well.
Can I install the Trooper sights myself?
Yes, it's a standard dovetail swap, but a sight pusher makes the job far cleaner and safer than a hammer and brass punch. The rear especially benefits from a proper tool so you don't mar the finish or crack a tritium vial. If you'd rather not risk it, any competent gunsmith can install them quickly.
