Frequently Asked Questions
Will this rear sight fit my Glock 43 or Glock 42?
No — the 6.9mm OEM fixed rear sight is not compatible with the Glock 42 or Glock 43. Those slimline models use a different, smaller sight platform. This sight is designed for larger Glock frames including the G20, G21, G29, G30, G31, and G32 series. Always verify your specific model before purchasing.
Do I need a special tool to install this rear sight?
Yes, a Glock sight tool or a universal pistol sight pusher is strongly recommended for proper installation. The rear sight slides into a dovetail cut on the slide and requires even, controlled pressure to seat correctly without damaging the sight or the slide finish. Attempting installation without the proper tool can result in misalignment or cosmetic damage.
How does the 6.9mm height affect my point of impact?
The 6.9mm rear sight height is the standard factory height for the compatible Glock models listed, meaning it is designed to work with the corresponding factory front sight height to produce a point-of-aim/point-of-impact zero at typical self-defense distances. If you are switching from a non-standard height rear sight, you may need to re-zero your pistol. Pairing this rear sight with the correct OEM front sight ensures the most accurate results.
