HD-002-S/U Extreme Service rear sight

HD-002-S/U Plain black fixed rear sight that fits slides machined for the LPA adjustable rear sight

 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.

The rugged HD-002 Extreme Service fixed rear sight is available plain black. It fits 1911 slides machined to mount the LPA adjustable rear sight as used by Springfield Armory and other 1911 manufacturers. The HD-002 is CNC machined and incorporates the most desirable features in a 1911 rear sight. The rear blade is serrated 50 lpi to reduce glare and reflection. All edges and corners are machine radiused for handling, carrying and operational comfort. The front face of the sight is squared to allow one-handed operation. The notch dimensions are .140" wide x .125" tall to allow adequate light into the sight picture, assuring a rapid sight acquisition and alignment. The HD-002 has become a favorite for use in custom installations, due to it's good looks and balanced proportions. In most cases, the HD-002 sight will regulate with a .180" tall front sight, which is what the factory Springfield front sight typically is.

  • Fits all Springfield Armory 1911 models with plain black adjustable sights, including the new Range Officer. 
  •  
  • Also fits some models of Para-Ordnance, Charles Daly, STI Spartan and other pistols machined for the LPA adjustable rear sight. Note- may require advanced level gunsmithing or modification of sight cut to fit these non-Springfield pistols.

  • Note - for Springfield 1911 pistols with factory installed adjustable night sights (like the TRP Operator), you need my HD-006 series sight
