Please Read: Sights are not "drop-in" parts, especially for 1911 pistols. There are so many companies, large and small, manufacturing 1911 pistols today and they all have different ideas about dimensional consistency in the sight cut. The only way after-market sight manufacturers can provide you with sights is to manufacture their sights and hold their dimensions on the high side of the range commonly encountered. This means that to install sights on 1911s, you often have to "fit" the sight to the sight cut by finding the surface on the sight that is too big and filing it down until the sight can be installed and still fit tightly. Sometimes it's more than a single surface that has to be fitted. There are instructions for fitting and installation as well as zeroing and calculating sight height in the Instructions tab on the home page. Please be aware of what you are undertaking and if you want some help, reach out to me for installation service. The cost is reasonable and the turnaround time is quick.
Created for us folk who have aged eyesight, this sight has a extra wide (.170" wide x .125" deep) rear sight notch. My intention was to use this in conjunction with the Trijicon HD front sight that I offer. Together, they combine to give a larger sight picture with lots of daylight on each side of the front sight blade which will let you a more clear focus on your sight picture than you've had in many years.
Fits slides machined for the .500" x 65° Novak Lo-Mount sight cut. The HD-004 sights are .325" tall at the rear blade, which is the standard Novak height. If you need the taller .375" tall version, see my HD-005-WU.
