Trijicon Fiber Optic Sight Set for Glock 17-45 Gen 1-5 - Red & Green Fiber Options

Trijicon fiber optic sights for Glock pistols combine a time-tested aiming solution with the durability you expect from the brand. This sight set fits Glock models 17 through 45 across generations 1–5, covering most of the Glock lineup that sees duty at the range, in the field, or behind the counter. Fiber optic front and rear sights collect ambient light to give you a bright sight picture in good conditions, and they're built on Trijicon's reputation for rugged reliability in combat and duty optics.

Available in red or green fiber options, the choice comes down to your preference and lighting conditions—both colors deliver quick target acquisition and are less dependent on battery power than electronic red dots. The sight set is engineered for Glock's dovetail cuts, making installation straightforward for anyone with basic gunsmithing tools or a qualified armorer.

Whether you're running your Glock as a carry piece, duty gun, or range workhorse, upgrading to a quality fiber optic sight set is one of the most practical improvements you can make. Fiber optics are proven in the field and will hold up to the wear and tear of regular shooting.

Frequently Asked Questions

Will these sights fit my Glock?

This sight set is compatible with Glock pistols 17 through 45, spanning generations 1–5. Check your Glock model number to confirm compatibility. Some Glock models outside this range or with custom slides may not fit without modification.

What's the difference between red and green fiber sights?

Both gather ambient light to brighten your sight picture. Red fiber is a traditional choice; green can offer faster target acquisition for some shooters under certain lighting conditions. The choice is personal preference and what works best in your typical shooting environment.

Do fiber optic sights need batteries?

No. Fiber optic sights are passive optics that rely on ambient light, so they don't require batteries or charging. They work well in daylight and indoor range lighting without any power source.

Do these sights come with installation tools or a sight pusher?

This listing does not include installation tools or a sight pusher. Installation requires a sight adjustment tool or Glock sight pusher, which you may need to purchase separately if you're installing them yourself.
