Description
The AmeriGlo Pro i-Dot takes a different approach than the usual three-dot sight picture. Instead of lining up three horizontal dots, you stack a single glowing front dot right over one rear dot centered below the notch. That vertical dot-over-dot alignment cuts down on the clutter and lets you find your front sight and press the trigger without overthinking it, which is exactly what you want when speed matters.
What Makes the Pro i-Dot Different
The front sight is where this set earns its keep. A green tritium lamp sits inside a high-visibility orange outline, so your eye snaps right to it in daylight and it glows on its own once the sun goes down. The front blade measures 0.140 inches wide at 0.22 inches tall, which is a nice balance of visible and precise. The rear is a clean square notch with one green tritium dot centered underneath, running 0.18 inches wide and 0.315 inches tall overall. No busy dots to distract you, just a simple reference that lights up when you need it.
Fit and Build on the AmeriGlo i-Dot Set
These are machined from steel and finished in matte black, so they hold up to daily carry and hard range days. The set drops into Glock Gen 1 through 4 models chambered in 9mm, .40, and .380, and Gen 5 models in 10mm and .45, covering the 17, 19, 22, 23, 24, 26, 27, 33, 34, 35, 37, 38, and 39. Worth noting up front: they are not cut for Glock MOS slides.
Real-World Use with the Pro i-Dot
Folks running these on carry guns like the G19 point to the orange front sight as the standout, calling it easy to pick up fast while the tritium keeps working in the dark. It's a solid middle ground between a target sight and a defensive setup, whether you carry every day, run drills at the range, or just want a sharper sight picture than the plastic factory sights. Installation calls for a sight pusher and a front sight tool, so plan on either grabbing the tools or having a gunsmith set them for you.

Frequently Asked Questions
Which Glock models does the AmeriGlo Pro i-Dot set fit?
This set fits Glock Gen 1 through 4 models in 9mm, .40, and .380, plus Gen 5 in 10mm and .45. That covers the 17, 19, 22, 23, 24, 26, 27, 33, 34, 35, 37, 38, and 39. It does not fit Glock MOS slides, so double check your slide before ordering.
How is the i-Dot sight picture different from a standard three-dot?
Instead of three dots lined up side by side, the Pro i-Dot uses a single front dot stacked over one rear dot centered below the notch. This dot-over-dot layout simplifies vertical alignment and lets you focus on the front sight faster. Many people find it quicker to run under pressure and less cluttered in low light.
Do the AmeriGlo Pro i-Dot sights glow in the dark?
Yes. Both the front and rear feature tritium lamps that self-illuminate with a green glow, so they work in low light and total darkness without needing to be charged by a light source. During the day, the orange front outline draws your eye for fast target acquisition.
Can I install these sights myself?
You can, but you'll want the right tools. A sight pusher for the rear dovetail and a front sight tool make the job much easier and help avoid marring the slide. If you don't have those on hand, having a gunsmith press them in is a quick and inexpensive option.
