Product Description

The 10-8 Performance rear sight is precision CNC machined from heat treated 4140 bar stock and finished in black QPQ salt bath nitrocarburizing (aka Melonite, same as the Glock slide). All 10-8 sights feature a U notch for rapid, intuitive alignment with a dot such as on our tritium insert and fiber optic front sights. The rear face is plain black, serrated at 40 lpi to reduce glare in varied lighting conditions.  

  • Fits: ALL Glock models, all calibers, all frame sizes, all slide sizes.  
    • EVERY Glock, including Gen 5, 19X, etc. all use the same front and rear sights.
    • The only Glocks with unique sights are as follows:
      • Glock 42/43 needs a shorter front and narrower rear, and use our model specific front/rear sights.
      • Glock MOS slides use the universal Glock rear dovetail, but located more to the rear. We have specific sights compatible with the MOS slide.
  • Notch widths: .140" and .156" U Notch
    • .140" - good balance of speed and accuracy
    • .156" - good for maximum speed, preferred for older eyes 
  • Compatible with .215" - .250" tall front sights (see below for more info)
    • most Glock models, regardless of caliber and generation, most commonly use the .215" front.  
    • Glock 34/35, 41, 17L, 24L most commonly uses the .235" front.  Sights do not overhang slide cutout.
    • Our rear sight is .250” net blade height above the slide
    • Use a notch width equal to or greater than front sight width.
    • NOT compatible in elevation with the Glock OEM, Trijicon OEM style, TruDot, Meprolight, TruGlo TFO front sights as they are too low.
    • XS Standard Dot front sights are .200" tall.  Our .156" notch rear is recommended, but we do not guarantee POA/POI due to the short height.
    • XS Big Dot front sight is .195" wide, and is too wide to work with any our sights.
    • Trijicon HD, GL101 Series front sight is .215" tall x .144" wide.  Our .156" notch rear is compatible.


User installation instructions included. Fitting is usually not required, but the QPQ/Melonite finish is harder than a normal steel file. It needs to be filed with a diamond file or hone (see Brownells.com), as files will slide right off the surface.

***Some newer production Gen5 guns may have oversized rear sight dovetails. If you experience excessively loose fit of our rear sight, please contact us for a return. Our sights are all the same size, so we are unable to provide you with a larger one.


Please contact us for a discounted price on additional front sights if your initial purchase does not provide the desired point of impact.

  1. Rear .140 Sights 5 Star Review

    Posted by on 14th Apr 2017

    This is my 2nd Set of 10-8 sights. The U-Notch is fantastic and fast to pick up. Hands down they are the best. Nothing else compares. Simply Quality!! Easy Installation.


  2. Top notch product 5 Star Review

    Posted by on 20th Oct 2016

    The best rear sight out there. The serrations and U-Notch make target aquisition and accuracy so fast and simple. Sight fit right on easily with no adjustments. I have this style 10-8 sight on all of the guns I frequently shoot. They never let me down. The 10-8 performance staff are so nice and professional and always promptly respond to questions.


  3. fit and finish is awesome 5 Star Review

    Posted by on 12th Sep 2016

    Very well made product. I will consider using these sights for the rest of my weapons in the future... You will like these rear sights.


  4. Great Sight 5 Star Review

    Posted by on 15th Aug 2016

    I have 10-8 rear sights on three different Glocks. They always install easily, without any need to be fitted or shaved. The sight picture is great. Overall, a quality made product., that I highly recommend.


  5. My favorite rear sight 5 Star Review

    Posted by on 15th Aug 2016

    I took a chance on a used 10-8 rear sight years ago after previously only ever running 3-dot setups. Since then every single handgun i've owned or currently own has a 10-8 rear sight on it. This is by far my favorite rear sight setup.
    Just recently got another Glock, ordered up my 10-8 sights for it and installed them at home very simply. Took it took the range the next day and everything is spot on.


  6. Highest Quality Exemplifies The Design 5 Star Review

    Posted by on 1st Jul 2016

    This is my third GLOCK I have installed these on and fit and finish were perfect. Easy installation with NO filing required. You can't get better than this, even though many other companies have come out with similair parts. 10-8 Performance was early to release their part and they consistently produce the highest quality parts.


  7. Great sites and easy to pick up fast. 5 Star Review

    Posted by on 20th May 2016

    Great sites and way less busy than the three dot set ups.


  8. 309Tactical supports 10-8! 5 Star Review

    Posted by on 9th Jan 2016

    Another sight for the shop.


  9. Great rear sight for CCW 5 Star Review

    Posted by on 15th Dec 2015

    Edges aren't sharp like Trijicon's. Wont dig into your skin. Great sight acquisition.


  10. Glock Rear Sight - .156 Width - A Sight for Sore Eyes 5 Star Review

    Posted by on 26th Oct 2015

    Having spent 30+ years in federal law enforcement and the military, I can appreciate a set of sights that are quick to acquire with acceptable combat accuracy. Now that I am retired, ailing eyes are even more demanding of a bit more air around the front sight post. Combined with a standard width front, the .156 rear sight offers extremely fast sight acquisition from the holster. I have this rear set up on a Glock 21 with a brass bead front and on a Glock 20 with a fiber optic front. Both work well for me for SD and recreational use. The rear sight was easy to install with only a couple of swipes with an emery cloth required. I find this a reasonable alternative to special purpose glasses that I would not use for everyday or attaching a red dot sight system, both of which tend to be expensive and less practical for my needs. YMMV
