Frequently asked questions

Do these sights work on all Glock generations?

The Ameriglo 4XL sights fit standard Glock dovetail cuts across Gen1 through Gen5 models. Verify your specific Glock's sight channel width before ordering to ensure proper fitment.

How long does tritium maintain brightness in these sights?

Tritium has a 12-year half-life, meaning brightness reduces gradually over time. Most shooters find acceptable illumination for 8–10 years of regular use before noticeable dimming occurs.
