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. 

Replacement rear sight for S&W 1911 fixed sight models (all generations of production, all models, all calibers) and new E Series 1911s.  Will also fit older DA/SA "Third Gen" fixed sight S&W Autos such as the 4506, 3913, etc.  Please note that due to the wide variances in production of the different 3rd Gen S&W models, we cannot guarantee this sight to work in all variants.  It is highly recommended that you measure your 3rd Gen gun prior to ordering.  

Features a .125" deep U notch, and .265" tall rear blade, which is directly compatible with the existing front sight (factory front is .125" wide x .135" tall).  Sight is the same height as the factory unit and will not affect point of aim.
