GS412 Includes: .015″ G-Shim (front sight shim)
Part Number GS412 (Standard .250” tall tritium rear sight with .225” tall tritium front sight)
All Glock models. Not for MOS.
One G-Shim is included with each set of GS412 Defense Tritium Standard Glock sights.
G-Shim increases the front sight height by .015” and will lower POI by 1”-3” on average, depending on the gun model and target distance. The G-Shim fit is tight on the front sight boss. Use only one G-Shim per front sight.
.225” tall (and the former .215”) front sights may produce a higher POI with most GEN 4, GEN 5 standard models and all Longslides. If POI is high, you can use a hold with more of the target visible above the front sight, also known as a “6-oclock” hold. G-Shim accessory can lower POI 1”-3” on average.
GS412 Defense rear sight will fit Slimline Glock models but will appear slightly large. Outer width of rear sight remains inside of slide width.
Part Number GS731 (Slimline .235” tall tritium rear sight with .225” tall tritium front sight)
Slimline Glock models. Not for MOS.
GS731 Slimline Defense rear sights will fit Standard Glock models but will appear small in relation to slide width.
DEFENSE TRITIUM SIGHT Notes:
Front sight height recommendations are determined by the Point of Aim (POA) and Point of Impact (POI) test results using factory stock Glock pistols with Sevigny Performance rear sights. Test distances are 45-75 feet.
Gun model, barrel type, ammunition, lighting and shooter all contribute to individual POA/POI results.
With drift adjustable only sights, it is recommended the shooter learns correct POA once point once POI elevation results are discovered.
