Handgun Sight Review: AmeriGlo I-Dot

The I-Dot sights are one of the newest offerings from AmeriGlo. Their name comes from their 2 dot design. Instead of lining up 3 dots horizontally like you would with most night sights, you align 2 dots vertically with the I-Dot sights. It’s like dotting an “i”. This design feels fast and intuitive in low light.

Front sight focus is easy with the I-Dot sights. This picture approximates the shooter's point of view (on a Glock 17 RTF2 for reference). Click to enlarge.

Stats

  • Front sight width: .125″
  • Rear sight notch: .180″
  • Price: $74

Front Sight

The I-Dot front sight is a pretty standard front sight. It has a tritium vile insert and a white outline.

The front sight is typical of most night sights. Click to enlarge.

Rear Sight

The I-Dot features an excellent rear sight. The notch is relatively wide (like most AmeriGlo rear sights) at .180″. This makes the front sight faster to pick up but may cost you some precision at longer distances. I find the speed gained is greater than the precision lost. It’s a worth while trade.

The bottom corners of the notch are rounded similar to a u-notch (unlike a true u-notch, the bottom is flat). These rounded corners serve to remove all of the hard edges from the sight picture except the important ones.

The rear sight features a single tritium vile insert that does not have a white outline which makes it appear smaller than the insert in the front sight. Everything about this rear sight is designed to help you focus on the front sight.

The I-Dot rear sight feature a single tritium vile that is not outlined and a wide notch with rounded corners. Click to enlarge.

The rear sight has many of it’s edges melted so it is snag free. However, the leading edge of the rear sight is left squared so that the sight can be used to cycle the slide in an emergency by catching it on a belt, holster, table top, or any other suitable surface. This may be an important feature if you train one handed manipulations.

The I-Dot rear sight has mostly "melted" corners except the leading edge which is intentionally left squared. Click to enlarge.

There is no shortage of options when it comes to excellent handgun sights. The AmeriGlo I-Dots have a slew of features and a price that makes them one of the top choices in a crowded field.

    I’ve always preferred the i-dot sights (i.e. Sig standard sights) over the glock or 3-dots… These look like some really nice night sights! I’ll have to give them a shot.

    Good review!
