1911/2011 Low Mount Rear Sight

$48.75

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
  • .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.
  • Springfield AOS iron sight cover plate
  • Dan Wesson Optic cut iron sight cover plate

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.

    10-8 Performance Low mount sight

    I have one of these sights on a Lightweight 10-8 Operator and love it. When my Springer Pro night sights died I replaced them with one of these.

    The standard for years

    When I was young and poor I would use a chainsaw file on rear sights to approximate the 10-8 rear sight picture. Now that I'm blessed with a little more money, I can simply buy the 10-8 rear. There is no better sight picture for rapid acquisition and also good precision. Nice that it is available in different notch widths. My 49 year old eyes like the widest notch for a little bit more daylight on either side of the front blade. Overall quality is top notch. Dovetail is slightly oversize. It takes a couple of minutes of filing to fit it to the slide but you know it's not going to come off. Far better than the opposite.

    These 2011/1911 10-8 performance rear sights are the best sights I ever bought, I highly recommend them to anyone looking for a ledge style rear sight, they are easy to install.

    1911 low mount Novak

    My Springfield 9mm Range Officer Operator consistently shot 4” to 5” high with its factory .350” fixed rear sight at 25 yards. I replaced it with a 10-8 .325” with 140” wide notch. Dead on and sure don’t miss the white dots.

    1911 U notch rear sight for 1911

    This is a really nice rear sight for a 1911, serrated , blacked out with your choice of U notch size. Great sight, very little fitting involved and fit good and tight. Quality thru and thru, thanks 10-8!!!!

    1911 Rear Sight

    10-8 rear 1911 is a Fantastic fit and quality for my Springfield mc operator. Very happy with this product

    1911/2011 Low Mount Rear Sight

    If 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.

    1911 lo mount sight

    This 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.
