Glock Factory OEM Fixed Rear Sight - 6.1mm (.240" height) - Model# SP00154. Designed to be interchangeable with all Glock Pistol models and is manufactured by Glock to the same exacting standards as the original, guaranteeing excellent fit and reliable operation. All factory Glock Fixed Rear Sights are interchangeable and elevation changes are made by switching out the rear sight (all factory Glock front sights are the same height). A shorter rear sight will lower the point of impact, whereas a taller rear sight will raise the point of impact. A one-step change (up or down) in rear sight height on a Glock 17 will result in approximately 2.4 inches of impact difference at 27 yards.
