Description

Factory Glock Rear Sight

This is Glock's own fixed rear sight in steel, 6.9mm (about 0.27 in) tall, with the familiar white U-notch outline. It replaces a damaged, worn or swapped-out rear sight with the factory part, so your pistol returns to its original sight picture. It suits owners of the listed Glock models who want a factory replacement, and armorers keeping factory-spec spares on hand.

Features

  • Genuine Glock OEM Part — OEM means original equipment manufacturer, so this is the same component Glock fits at the factory, part number SP04204.
  • Steel Construction — The sight body is steel rather than polymer, so it holds its shape better against knocks and holster wear.
  • 6.9mm Sight Height — Rear sight height sets where the gun shoots relative to the front sight, so match this 6.9mm height to the front sight your pistol uses.
  • White U-Notch Outline — A white insert frames the rear notch, giving your eye a clear reference for centering the front sight quickly.
  • Fixed Design — The sight has no adjustment screws or moving parts that can drift or loosen once installed.
  • Dovetail Base — The angled base slides into the dovetail, the tapered slot cut across the top of the slide that holds the rear sight in place.
  • Black Finish — A matte black surface keeps glare off the sight so the white outline stands out.
  • Glock Logo Marking — The Glock logo is molded into the top of one sight ear, identifying it as a factory part.

Fit And Installation

This sight fits the Glock 20, 20SF, 21, 21SF, 29, 29SF, 30, 30SF, 30S, 31, 32, 36, 37, 40 and 41. Check your model against this list before ordering, since rear sights for other Glock frames differ. Installation means drifting or pressing the sight into the slide dovetail, and a gunsmith or a dedicated Glock sight tool makes the job straightforward.

    Fixed My Low Shooting Problem

    I was shooting low with the factory 6.1mm sight on my G30 and this 6.9mm fixed that right up. Went to the range and was finally putting holes where I wanted them at 15 yards instead of 3 inches low. Only thing I'll say is it was a pretty tight fit going into the dovetail, had to use a sight pusher tool and even then it took some effort. But once its in there its SOLID and I know its not going anywhere. Way better than the plastic sights that come stock.

    Steel construction is way more durable than the plastic OEM sights
