Overview

Built for pistols equipped with red dots, this sight set serves as a backup or co-witness iron-sight option for shooters who want a simple sight picture alongside an optic. The blacked-out front and rear sights keep the setup understated, while the tall profile is intended for use on compatible GLOCK models when pairing the pistol with a mounted light. It is not compatible with the GLOCK 42, 43, 43x, or 48, so fitment should be checked before purchase. Green tritium is included, though the product notes that it is less important when the sights are backlit by a white light in low-light conditions.

Pros

  • Compatible with most GLOCK models, excluding the 42, 43, 43x, and 48.

Considerations & Trade-offs

  • Designed for backup or co-witness use with pistol-mounted red dots, so it is not a standalone sighting solution for every setup.
  • Compatibility excludes GLOCK 42, 43, 43x, and 48, so fitment should be checked before purchase.
  • The front and rear sights are blacked out, which may be less useful if you want a brighter daytime sight picture.
  • The product notes that a white light can make the tritium less important in low light, so the illumination benefit depends on your setup.
