Description
Tritium night sights with a thin front post for Glock large-frame pistols, made for law enforcement users who need precise target identification at longer distances.
These HD XR night sights build on the HD night sight design and pair a thinner front sight post with green tritium lamps front and rear, for identifying targets and engaging them at increased distances in any light.
The front sight has a yellow outline and the rear sight a black outline, with a U-notch rear.
The set fits Glock 20, 21, 29, 30, 36, 40, and 41 (including S and SF variants, excluding MOS models).
Key features
- Wider field of view — The thin front post (.122 in. width) gives a larger field of view for fast target identification and engagement at longer distances.
- Front sight acquisition — A photoluminescent-painted front outline combines with a subdued U-notch rear to draw the eye quickly to the domed sapphire and tritium front sight in all lighting conditions.
- Brighter aiming point — The domed sapphire cap on the front sight focuses the tritium illumination for a 2X brighter aiming point.
- Visible in low light — Tritium phosphor-filled glass lamps illuminate the sights for high visibility in no-light and low-light situations.
- Recoil and solvent protection — The tritium gas lamps sit inside protective aluminium cylinders with additional silicone rubber cushioning, protecting them from heavy recoil and harsh cleaning solvents.
- Sapphire lamp caps — Each tritium lamp is capped with a sapphire jewel that distributes the light evenly and adds protection against puncture and cleaning solvents.
Typical applications
- Duty pistols used by law enforcement agencies that need precise engagement in any light.
- Longer-distance target identification and engagement with Glock large-frame pistols.
- Installation by a gunsmith or armourer is recommended.
