Glock Rear Sight, Gen2

$48.75

Our Gen2 sight upgrades our very popular Classic Glock Rear Sight with the new Gen2 features - coarse serrations on the front ledge for improved racking, scooped blade profile for better downrange visual awareness, and updated dovetail dimensions for Gen5 guns with oversized dovetails.

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.
    • DOES NOT FIT: Glock 42/43/43x/48, due to narrower slides.
    • DOES NOT FIT: Glock MOS slides, which use the universal Glock rear dovetail, but located more to the rear. We have specific sights compatible with the MOS slide.
  • Notch: .140" and .156" wide U Notch
    • .140" - good balance of speed and accuracy
    • .156" - good for maximum speed, preferred for older eyes 
    • Notch is .120" deep
  • 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.


Fitting is usually not required, but Glock slide dovetails have varied significantly during production and sometimes the sight won't drift in without some fitting. The QPQ/Melonite finish of these sights is harder than a normal steel file. If the sight is too tight and needs to be filed, use a diamond file or hone (see Brownells.com), as files will slide right off the surface. 


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

    Black Rear Sights

    These black rear sights coupled with Fiber Optic Front Sights are fantastic, especially for those with older eyes. Buy without hesitation, you will not be disappointed.

    Glock Rear Sight

    I love 10-8 sights. I have them on ALL of my personally owned Glocks. I wish I could change out the sights on my police department issued Glock 17.

    G19 Front/rear sights

    Senior eyes here; took Hilton’s recommendation and went with the 0.156” rear, 0.125 front. This is a carry gun and the front sight is a beacon easily found with plenty of daylight from the rear sight.

    Rear sight rocks!

    I have used a handful of different brand Glock sights, including an older 10-8 rear sight. This new model is my all time favorite. I like the plain wide U notch paired with orange surround tritium front. Sight has serrations on forward notch to facilitate racking one handed in an emergency - very cool. It fit my Glock dovetail well (using MGW pusher), and I like the additional set screw.

    GEN II Glock Rear Sight

    After careful review of the available sights on the market, I chose the 10-8 Performance GEN II Glock Rear Sight for my Glock 34. The price was good and delivery was fast. I removed the older rear sight with an MGW sight pusher and then pushed in the new 10-8 Performance sight. It went on correctly and fight tightly. My only issue was that I foolishly took the set screw out of the sight and promptly lost the bloody thing. Hopefully, Hilton will have mercy on me and send me another.

    GEN 2 REAR SIGHT FOR GLOCKS

    First off the 10-8 GLOCK GEN 2 REAR SIGHT is asthetically pleasing. I really like the serrated lines on the rear of the sight, it aides nicely in acquiring the front sight quickly and reduces any visual distractions you might find with rear sights that have tritium vials on each side of them. I have the 10-8 performance front sight that has the yellow polymer ring around it, which when I paired the front with the GEN 2 REAR SIGHT on my GLOCK 21, it helped me focus on the front sight. I’ve researched and read reviews about 10-8 performance products, and after using them, I can say that the reviews of how good their products are is not exaggerated. I plan on purchasing another 10-8 GEN 2 REAR SIGHT,as well as their yellow front sight and placed them on my other GLOCK PISTOL.
