Description
Green tritium night sight set with a yellow-outlined front and black-outlined rear for Glock large-frame pistols, made for tactical shooters.
This night sight set is designed for Glock pistols and fits models 20, 21, 29, 30, 36, 40, and 41 (including S and SF variants, excluding MOS models).
The front sight has a taller blade and an aiming point with a yellow outline, while the rear sight has a black outline and a wider U-shaped notch. Both sights use green tritium lamps.
Key features
- Front sight acquisition — A photoluminescent-painted front outline and a subdued U-notch rear draw the eye quickly to the front sight in bright, transitional and no-light conditions.
- Brighter front sight — The domed sapphire cap on the front sight focuses the tritium illumination for a 2X brighter aiming point.
- Visible without batteries — Tritium phosphor-filled glass lamps illuminate the sights for high visibility in no-light and low-light situations.
- Recoil protection — The tritium gas lamps sit inside protective aluminium cylinders with additional silicone rubber cushioning, protecting them from heavy recoil and harsh cleaning solvents.
- Even light distribution — Each tritium lamp is capped with a sapphire jewel that helps distribute the light evenly and adds protection against puncture and cleaning solvents.
- One-handed slide operation — The steeply hooked front surface of the rear sight assists in emergency one-handed slide manipulation.
Typical applications
- Duty and tactical pistol use in bright, transitional and low-light conditions.
- Upgrading Glock large-frame pistols with a night sight set.
- Installation by a gunsmith or armourer is recommended.
