AmeriGlo
The AmeriGlo I-Dot night sights for Glock 42/43 are purpose-built for shooters who need fast, reliable target acquisition in low-light conditions. The I-dot design stacks a front tritium dot over a rear tritium dot, creating an intuitive vertical alignment method that cuts down the time between drawing and getting on target—a genuine advantage in any defensive scenario. Paired with AmeriGlo's extended rear sight, these sights give you a slightly longer sight radius than factory Glock sights, which naturally improves sight picture and consistency when it matters most.
What sets these sights apart is attention to detail in real-world shooting. The green tritium front sight pairs with a bright white outline, making the front sight pop without bleeding your night vision in tactical or home-defense lighting. The rear sight is green tritium with a square notch and an undercut face to kill glare—a design choice that works just as well indoors under artificial light as it does outdoors. All of that sits in a steel frame finished in matte black, so there's no shine to betray your position or distract in low light.
AmeriGlo builds these for Glock 42 and 43 pistols specifically, so if you carry either of those slim single-stacks, you're getting a direct fit. Installation requires basic gunsmith tools or a professional hand, but once they're zeroed, you'll appreciate the confidence that comes with sights you can actually see when the sun goes down.

Yes. The AmeriGlo I-Dot GL-105 is engineered specifically for Glock 42 and Glock 43 pistols.
The I-dot stacks a tritium dot on the front sight over a tritium dot on the rear sight, which speeds up vertical alignment. This dot-over-dot method cuts target acquisition time in low light and makes it easier to establish a consistent sight picture quickly.
Both the front and rear sights use green tritium, which is visible in darkness without requiring light activation. The white outline on the front sight makes it easy to pick up even in dim interior lighting, while the undercut rear face prevents glare that can wash out your sight picture in artificial light.
Yes. The rear sight is extended compared to factory Glock sights, which increases your sight radius. A longer sight radius naturally improves accuracy and sight picture consistency at the range and in the field.
