HD-002-S/U-T2 Night Sight - 2 Dot

Extreme Service rear night sight for Springfield Range Officer and other LPA adj. sight cuts

The rugged HD-002-S/U-T2 Extreme Service fixed rear night sight is manufactured with two genuine Trijicon tritium lamp installed one on each side of the sight notch, giving an "Three Dot" night sight picture. This sight 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 in the USA and incorporates the most desirable features in a 1911 rear sight.

The rear blade is serrated 50 lpi to reduce glare and reflection. Has 2 set screws for extra mounting security.

The "Stealth Dot" tritium lamps are mounted extra deep in the sight blade to reduce the possibility of glow from a holstered weapon giving you away in pitch black. In daytime, the rear lamp is nearly invisible, letting your eyes focus on the front sight easily. No confusing, cluttered sight picture.

All of the 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 of slide.

The HD-002 is offered with either a square notch or a U notch and dimensions are .140" wide x .125" tall to allow plenty of light into the sight picture, assuring a rapid sight acquisition and clear alignment. Great for aging vision or rapid use.

The HD-002 has become a favorite for use in custom installations, due to it's good looks and balanced proportions. The HD-002 will often regulate with the OEM front sight, or with new installations using a front sight height in the range from .140" to 180", depending on the pistol. 


  • 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
  • Fitting for installation (measuring and filing to fit) is required in most cases

There are detailed instructions for fitting and installing the rear sight at and instructions for zeroing and locking down your sights at
