AmeriGlo GFT113 Specialty Sight Set for Glock - Red Fiber Optic Front & Black Rear Sights

The AmeriGlo GFT113 specialty sight set for Glock combines a bright red fiber optic front sight with a crisp black rear sight, giving you speed and precision whether you're at the range, in a tactical training scenario, or carrying concealed. This is a working set of iron sights built for shooters who want day-in, day-out reliability without complexity. The pairing of a narrow front blade with a properly proportioned rear notch is tuned for quick target acquisition and consistent alignment.

AmeriGlo engineered these sights for everyday use on Glock platforms. The red fiber optic front element gathers ambient light to stay visible in variable conditions, while the flat black rear sight absorbs light and eliminates glare—a proven combination for defensive and competition shooters. Both front and rear are case hardened for durability. If you're running a Glock with Modular Optics System (MOS) cuts, this set is compatible with that platform as well.

Whether you're upgrading factory sights or building out a defensive carry gun, the GFT113 gives you a no-nonsense sight picture backed by AmeriGlo's reputation for quality manufacturing. These sights work on a range of Glock generations and calibers, making them a practical choice for pistol owners who run multiple guns or have a core carry piece that needs dependable iron backup sights.

Frequently Asked Questions

Which Glock models and calibers does the GFT113 fit?

The AmeriGlo GFT113 is compatible with Glock Gen 1–4 pistols in 9mm, .40 S&W, and .380 Auto, as well as Gen 5 pistols in 10mm and .45 ACP. It also works with Glock MOS-equipped slides.

Can I use these sights as a backup to a red dot optic?

Yes. The GFT113 is MOS-compatible, so it will coexist with an optic mounted on an MOS slide. The red fiber optic front and black rear sights will serve as iron backup sights if your optic fails or needs to be removed.

What's the difference between the fiber optic front and the flat black rear?

The red fiber optic front sight gathers available light to stay visible in low-light and transitional conditions, speeding target acquisition. The flat black rear sight minimizes glare and provides a clean reference point for alignment. Together, they offer a high-visibility front paired with a non-reflective rear—a time-tested setup for defensive shooting.

Are these sights adjustable for windage and elevation?
