Who This Is For
This sight is ideal for Glock owners who need a reliable OEM replacement after a lost, damaged, or worn rear sight — as well as G17L shooters seeking the correct standard-height fixed rear to pair with a factory or aftermarket front sight.

Frequently Asked Questions
Will this rear sight fit my Glock 19, 17, or 26?
Yes — this 6.1mm OEM fixed rear sight is compatible with the vast majority of Glock pistols, including the popular G17, G19, G26, G34, and many more. The only exceptions are the Glock G42 and G43, which use a different, narrower sight dovetail. Always verify your specific model before ordering if you are unsure.
What does the 6.1mm height mean, and how do I know if it's correct for my setup?
Sight height (6.1mm) refers to the measurement from the base of the sight to the top of the sight blade. This is the factory standard height for the Glock G17L and is commonly used as a replacement height across many other Glock models. If you are replacing a stock rear sight with a like-for-like part, 6.1mm is typically the correct choice. If you have installed a taller aftermarket front sight, you may need a taller rear sight to maintain a level sight picture — consult your front sight specifications or a qualified gunsmith if in doubt.
Do I need a special tool to install this rear sight?
Glock rear sights are press-fit into a dovetail cut on the slide and require lateral force to seat properly. A dedicated sight pusher tool is strongly recommended to avoid damaging the sight or the slide finish. While some experienced shooters use a brass punch and mallet, a quality sight pusher provides far better control and a cleaner installation. Professional installation by a qualified gunsmith is always an option if you are not comfortable performing the swap yourself.
