Description
Bringing your FN High Power into the modern era of low-light shooting starts at the sights, and the AmeriGlo i-Dot set is one of the cleanest upgrades you can make to the 2023 High Power. It ditches the traditional three-dot arrangement in favor of a dot-over-dot design, which is exactly what it sounds like: line up the rear tritium dot directly under the front dot and you're on target. That vertical stacking cuts down on the mental gymnastics of aligning multiple dots, so your eye finds the front sight faster and stays there.
What Makes the i-Dot Setup Different
The front sight carries a green tritium lamp surrounded by a LumiGreen photoluminescent outline. That outline soaks up ambient light and glows on its own during the day, giving you a high-contrast aiming point when the sun's out, then the tritium takes over once things go dark. The rear sight keeps things minimal with a single green tritium dot sitting below a square notch, which delivers the clean contrast you want without a cluttered sight picture. The whole idea is speed, and it shows the moment you press the gun out.
Built to Take a Beating
These aren't flimsy factory-style sights. AmeriGlo machines them from high-strength steel with a case-hardened finish, so they hold up to hard use, holster wear, and repeated draws without complaint. The tritium is self-powered and needs no batteries, meaning your sights are ready whenever you are, whether that's a 2 a.m. bump in the night or a full day at the range.
Fit and Fitment for the FN High Power
This set is cut specifically for the FN 2023 High Power, so you're getting a proper fit rather than a forced compromise. It's a complete front and rear package, sold as a matched set. Like most pistol sights that drive into dovetails, installation goes best with a proper sight pusher or a trip to your local gunsmith to keep everything seated square and zeroed.

Frequently Asked Questions
What does the dot-over-dot design on the i-Dot sights do?
Instead of lining up three separate dots, you stack the single rear tritium dot directly beneath the front dot. This makes vertical alignment quick and natural, which speeds up how fast you get on target. It's a big part of why folks like the i-Dot layout for defensive and everyday carry use.
Will this AmeriGlo set fit my FN High Power?
This set is designed specifically for the FN 2023 High Power under part number FN-301. It's cut for that pistol's dovetails, so you get a proper match front and rear rather than a universal-fit compromise. If you're running the current FN High Power, you're in the right place.
Do the LumiGreen outline and tritium need batteries?
No batteries anywhere. The green tritium lamps are self-powered and glow on their own in the dark, while the LumiGreen outline is photoluminescent, meaning it charges off ambient light and glows during the day. Between the two, you get a visible front sight around the clock.
Can I install these sights myself?
It's possible if you have the right tools, but these are dovetail sights that need to be driven in and seated square. A proper sight pusher makes the job clean, and a lot of people just hand it off to a gunsmith to guarantee the fit and keep the pistol zeroed. Take your time either way so nothing gets marred or misaligned.
