Frequently Asked Questions
Will this rear sight fit my Glock 19 or Glock 17?
Yes — the 6.9mm polymer fixed rear sight fits the vast majority of Glock full-size and compact models, including the G17 and G19. The exceptions are the slimline G42 and G43, which use a different, narrower rear sight dovetail. If you're unsure, verify your model's required sight height before ordering, as Glock offers multiple height options (6.1mm, 6.5mm, 6.9mm) for adjusting point of impact.
Do I need a special tool to install this rear sight?
A standard Glock-compatible sight pusher tool is strongly recommended for proper installation. While some shooters use a brass punch and mallet, a dedicated sight pusher minimizes the risk of damaging the sight or the slide's dovetail channel. Many local gunsmiths and Glock-certified armorers can install this sight quickly and affordably if you prefer professional installation.
How does the 6.9mm height affect my point of impact?
Sight height directly influences where your rounds impact relative to your point of aim. The 6.9mm rear sight is the factory-standard height for the models listed and is designed to work in conjunction with a standard-height front sight for a correct point of aim/point of impact relationship at typical defensive distances (7–25 yards). If your pistol is shooting high or low, switching to a taller or shorter rear sight can help dial in your zero without modifying the front sight.
