What Glock models with these sights fit on?

  • These sights will fit on the Glock 17, 19, 22, 23, 24, 26, 27, 31, 32, 33, 34, 35 and 36.


What does this package include?

  • When you purchase this product, you will get a front and rear sight set from XS Sight systems.  The front sight is a big dot sight that has a green tritium insert.  The tritium allows you to use your sights in low light situations, when your sights would otherwise be extremely difficult to use.  The rear sight also has a tritium insert, giving you a two-dot sight picture.


Why Should You get Big Dot Sights?

  • XS sights are known for their big dot front sight and v-notch rear sight.  The reason why the designers at XS sight systems departed from the traditional notch and post sights is because they wanted to develop something that was easier to use under stress.  After exhaustive development and getting feedback from real-world evaluators, the Big Dot and V-Notch sights were developed.  Some have found them to be much easier to use under stress than traditional sights.  The big dot front sight allows for fast and easy sight acquisition and lining it up in the v-notch rear is easy and intuitive.
