Glock OEM Generation 5 Fixed Rear Sight - Polymer

Factory Glock Rear Sight

This is the polymer fixed rear sight Glock fits to its Generation 5 pistols at the factory. It is an OEM part, meaning it comes from the original equipment manufacturer and is the same sight a new Gen 5 ships with. Fit it to replace a damaged or worn rear sight, or to return a slide to factory configuration after trying aftermarket sights. It suits owners who want the standard Glock sight picture without changing anything else.

Features

• Genuine Glock OEM Part — Made by Glock for its own pistols, so it matches the factory fit and sight picture exactly.
• Generation 5 Specific — Designed for Gen 5 slides, the current Glock pattern with its own sight dimensions.
• 6.5mm Sight Height — The 6.5 marking inside the notch is the rear sight height, which should match a standard Glock front sight for the expected point of impact.
• White-Outline U-Notch — A white U painted around the notch frames the front sight dot so your eye finds alignment quickly.
• Fixed Configuration — The sight does not adjust for windage or elevation, so there are no screws to drift or work loose.
• Polymer Body — The black polymer body is light and matches the finish of the factory slide.
• Metal Base Strip — A metal strip runs along the base of the sight where it seats into the slide.
• Part Number SP39724 — The factory part number makes it easy to confirm you are ordering the correct replacement.

Fit And Compatibility

This sight is listed for the Glock G17, G19, G19X, G26, G34 and G45 in Generation 5. It is not intended for earlier generations, so check your slide before ordering. Rear sights come in several heights, and the height changes where rounds land relative to the sights, so keep the 6.5mm rear paired with a matching front if you want factory point of impact. Installation uses a sight pusher or similar tool, and a gunsmith can fit it if you do not have one.
