Heinie's Ultra Low Mount Ledge style rear sight for use on full size 1911 pistols with a suppressor that use a .500 x 65 degree dovetail. This set is designed to replace the factory installed sights and will not change the POA/POI of your pistol. The Ledge style rear sight is designed for quick aquisition of the front sight utilizing a wider notch width of .156. The rear face is serrated and has enough material to cycle your pistol single handedly with whatever surface is available. In addition, this sight set has the legendary Straight Eight configuration (for low-light and nightime shooting) that align vertically. This vertical alignment is proven to be faster and less confusing for the human eye.
The Heinie Ultra Low Mount rear a .500 x 65 degree dovetail cut. The front sight does require minor fitting for installation.

If the item is determined defective, Heinie will send the sight out for the tritium vial to be replaced (in the originally purchased product). We do not replace the entire sight, only the tritium will be replaced. Turn around time to replace a broken or defective tritium vial usually takes about 3-4 weeks.
