Glock 42/43 OEM Rear Night Sight

Features

1. Factory Glock OEM Part — Genuine Glock-manufactured replacement sight (part number SP33578) built to the same specs as the sights installed at the factory.
2. Tritium Illumination — Two self-illuminating tritium vials deliver a glowing rear sight picture in low-light, no-light, and transitional lighting conditions.
3. White Outline Dots — High-contrast white rings around each tritium lamp give you a fast, easy-to-acquire 3-dot sight picture in daylight as well.
4. 6.1mm Slim Profile — Slim 6.1mm height is purpose-built to match the narrow slide geometry of the Glock 42, 43, 43X, and 48.
5. Steel Construction — Machined steel body stands up to holster wear, hard use, and the recoil cycle of daily carry.
6. Gas Nitration Finish — Treated with the same Gas Nitration process used on Glock slides for a true color match and excellent corrosion and wear resistance.
7. Standard Glock Dovetail — Drops into the factory rear dovetail cut on compatible slides — no slide modification required.
8. Fits Glock 42, 43, 43X, and 48 — Direct replacement for the slim-frame Glock single-stack and slimline 9mm/.380 pistols.
9. Long Tritium Service Life — Tritium lamps provide reliable illumination for years of carry without batteries, switches, or maintenance.
