The 10-8 Performance rear sight is precision CNC machined from heat treated 4140 bar stock to better resist the nicking and denting that is typical with the wear and tear of daily carry. All 10-8 sights feature a U notch for rapid, intuitive alignment with dot such as on our tritium insert, brass bead, and fiber optic front sights. The rear face is serrated at 40 lpi to reduce glare in varied lighting conditions.  The sight blade is thick enough to allow setting in tritium vials as dots or bars if one so chooses, but we recommend leaving them without inserts in order to draw the eye toward the front sight.  The sight body is contoured and dehorned for comfortable handling and carry.  All rear sights feature a plain black blade finished in matte black oxide. 

Most factory sight setups feature a rear notch that is the same width as the front blade - ie. typically a .125" wide rear notch with .125" wide front sight.  This type of setup provides a relatively tight visual window that optimizes precision for maximum accuracy.  For most shooters with good vision, this combination works fine.  An increasingly popular combination is the .140" rear notch with a .125" width front blade.  For most shooters, this combination offers improved speed on close range targets without degrading perceived accuracy out to 25 yards.  The .156" extra wide notch is compatible with the XS Standard Dot (.110” width) or XS Big Dot (.161” width)  front sights, and also makes for a very quick combination in conjunction with our .125" wide front sights.  Hilton's "signature" set is the .140" wide rear notch with a .100" wide fiber optic front, or the .156" rear with the .125" brass bead front.

Our 02 series sights will fit into the popular Novak LoMount ® dovetail, which is found on fixed sight 1911s offered by Wilson Combat, Rock River, Dan Wesson, Ed Brown, Springfield Armory, Colt (XSE/Gunsite), Nighthawk, Les Baer, DoubleStar, STI, Sig (GSR and 1911s) and others.  They will fit your slide with only hand fitting of the sight if the dovetail is already cut, otherwise your slide will need to be machined.  **The 02 series sights DO NOT fit: Kimber, ParaOrdnance, Taurus, or S&W 1911s.  

The rear sights are available in heights to match your existing rear sight height, and will therefore be directly compatible with your existing front sight.  You will want to measure your existing rear sight before ordering.  If your gun already has a LoMount style rear sight on it, our rear sight will be directly compatible with your existing front sight in both height and width.

Please note that Springfield Armory fixed sight 1911s (Loaded, TRP, Professional, EMP) use both .325" and .375" tall sights.  It is not possible for us to predict what is on your gun, as each individual sample can vary without regard for model number etc.  It is best for you to measure the sight on YOUR gun to be sure.

Choose from .325" ("standard") blade height or .375" ("extra tall") blade height (most common on Officer/Defender length 1911s or various Springfield fixed sight 1911s).
