Product Description

Kensight® Adjustable Front and Rear Sight Set for the Compact Large Frame Glock®, .350" Tall Front (980-821)


We all know the factory Glock® sights leave more to be desired. In addition, the factory fixed sight dovetail, placed at the very rear of the slide, is small, shallow and not generally seen as ideal for an adjustable sight.  Kensight has designed sight set to fit the LARGE FRAME Glock pistols, Kensight Item# 860-817.  This fully adjustable rear utilizes the factory dovetail without having to modify the slide.  It is precise and practical, well-built and able to withstand a lifetime of use.  Because it is a fairly tall sight that sits completely on top of the side, a front sight with a minimum height of .315” is necessary. This is why Kensight had beveled the rear blade to prevent snagging and to protect the shooters hands.  This sight is fully adjustable for windage and elevation.  With positive clicks, a simple turn of the screw will let you dial it in to shoot at any reasonable distance. Not only is the sight highly effective and easy to use, it looks good too!  Knowledgeable shooters will note that our rear sight blade does not extend past the rear of the slide like many other adjustables that can extend 1/4" past the slide, putting your hands and clothes at risk.

This sight set’s front, Kensight item# 870-931, is fully serrated, .100” wide and .350” tall.  This sight was designed for use with a suppressor but is also to be used when shooting longer distances or when a higher sight is just necessary. This .350" front can be used on sub compacts, full size and long slide Glock pistols when shooting longer distances. Please keep in mind that it MAY be too tall for holsters that don’t have a front sight rib or recess extending the length of the holster’s pocket.  Very simple to install, it is held in with a screw that is provided with this set.  No sight or slide modification is necessary.
