Pros

  • Black QPQ finish reduces glare from the sight surface

Considerations & Trade-offs

  • Designed specifically for suppressor-height and optic co-witness use, so it is not a general-purpose front sight for standard-height setups.
  • Fits all Glock pistol models except the G42 and G43, so compatibility should be checked before ordering.
  • The 0.315-inch height is an extra-tall profile, which may require matching rear sight height for a complete sight picture.
  • Black QPQ finish and 40 LPI serrations are functional details, but the sight is still a single front-sight component rather than a full sight set.

Suggested Comparisons
