Frequently Asked Questions
Will this adjustable rear sight fit my Glock 19 Gen 5?
Yes, this Glock OEM adjustable rear sight is compatible with the Glock 19 across generations, including Gen 3, Gen 4, and Gen 5, as well as the G17 and G34. The one exception is the subcompact G42 and G43 models, which use a different, smaller sight platform. If you're unsure, verify your model number before ordering.
Do I need any special tools to install and adjust this sight?
Installation typically requires a sight pusher tool or a punch and mallet to seat the sight in the dovetail. Once installed, a small flathead or mini screwdriver is needed to turn the elevation and windage adjustment screws — note that a mini screwdriver is not included with this sight. A standard sight adjustment kit or Glock armorer's tool set will handle the job without damaging the sight or slide.
How does this sight compare to Glock's standard fixed rear sight?
Glock's standard factory rear sight is fixed, meaning your point of impact is set and cannot be changed without replacing the sight entirely. This OEM adjustable rear sight allows you to fine-tune both elevation and windage on the fly, making it far more versatile for competition shooting, load development with different ammunition, or correcting point-of-impact discrepancies. The white contrast insert on both sights provides the same fast acquisition you're used to from Glock's factory setup.
