Glock Fiber Optic sights


Our .215” tall, .125” wide front sight is big enough to be visible yet narrow enough for extreme precision.  The .060” diameter fiber optic gather’s light and fluoresces for extreme visibility in the bright light conditions common to practicing at ranges and competition shooting events.   

The .145” wide notch and crisp, defined edges on the rear sight allows for good visibility around the front sight blade for fast acquisition and precision alignment.  The serrated rear face prevents glare to increase the ease of front sight focus. 

The XS Sights fiber optic sights are a great choice for shooters who want a dedicated pistol for competition and training or if this is their first upgrade.  While offering a similar sight picture to our R3D or Minimalist sights, these fiber optic sights feature a bright insert specifically designed for bright lighting conditions at practice ranges or pistol matches.

Upgrade Your Sights!

Looking to customize your Glock? Sights are the perfect upgrade. Factory sights on Glock handguns have a few issues, and XS Sights has you covered! The first common problem with factory sights is the plastic construction, causing them to malfunction by breaking or moving after use. XS Sights are constructed from steel, ensuring they are durable and will hold up to the wear and tear of training. The second major issue with factory sights is the sight picture itself being difficult to see in different scenarios. Our fiber optic sights address this issue by including a vibrant front sight that is hard to miss in bright light settings. These are just a few of the many reasons to make your first Glock upgrade, an upgrade to XS sights!
