Fixed rear sight with single tritium lamp

Please Read -

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.

This sight is offered in either Square notch (S) or U Notch (U) both dimensions are .140" wide x .125" tall to allow adequate light into the sight picture, assuring a rapid sight acquisition and alignment.

The T1 Night Sight configuration gives you an "Over/Under" pattern for the tritium lamps  giving a clean simple view of your sights in the dark.

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
