Our classic 10-8 Performance rear sight design, featuring a Lo Mount dovetail, CNC machined from hardened 4140 bar stock and finished in black oxide. Rear face is serrated at 40lpi to reduce glare, with a .125" deep U notch. Features ledge profile and serrations on the front for optimized use as a racking surface. These will fit most 1911s with the popular Novak Lo Mount dovetail, as well as the fixed sight STI/Staccato 2011 pistols.
Blade Heights (see photo gallery for where to measure):
- .325" - Most common height used by manufacturers and suggested height for custom builds
- .340" - For the 4.15" barrel 2019 Staccato P, as well as the various 4.15" barrel legacy models such as the Tactical. Same as factory height.
- .350" - For the 3.9" barrel Staccato C, C2, as well as legacy models such as the DVC Carry. Same as factory height. Also fits many newer Springfield Armory 1911 models with .350" tall rear sights.
- .375" - For any of the above models which may shoot low. Raises impact at 25 yards approximately 6-7" from .325", 4-5" from .340" and approximately 3" from the .350".
**Does NOT fit adjustable sight STI/Staccato 2011s, DUO models, or DUO iron sight adapter plates.
Please note that our sights are made to consistent dimensions, and we can't be 100% certain how any given manufacturer cuts their dovetails. Our sights usually fit with some hand filing of the sight base. Unmodified GI dovetail slides will need to be machined. Please note that 1911 Low Mount dovetails vary wildly in dimensions. Our sights are meant to provide an interference fit, and not be dependent on the set screw for retention. It is not uncommon for some dovetails to be too large for our sight.
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 (see photo gallery for the critical dimension). 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 may have .325", .350", or .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.
The left front of the sight has a small angle machined into it. This is for easier installation, and is not a machining error.
ReviewsDaveIf available, a 10-8 U notch rear sight always resides on my pistols. Still not ready for a red dot but the 0.156" rear notch is fast in target acquisition.Christopher S Weismann
1911 lo mount sightThis sight requires minimal fitting. Anyone with some 800 grit paper and a set of diamond files can make this fit. A sight pusher is definitely a good idea. Fits my 9mm Range Officer elite perfectly.Steve
Very niceSuper high quality and well built. A+Manny Fusaro
