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 dot such as on our tritium insert, brass bead, and fiber optic front sights. The rear face is plain black, serrated at 40 lpi to reduce glare in varied lighting conditions.
User installation instructions included.
Please contact us for a discounted price on additional front sights if your initial purchase does not provide the desired point of impact.

Purchased this rear sight for a Glock 21, Gen 4. Selected the .140 rear sight opening and coupled it with a .215 height/.125 width tritium 10-8 front sight. Installation of the rear sight was easy, very minor fitting that only required a few strokes with a triangle file. Probably would have gone in fine without any fitting at all. Results were fantastic -- point of aim = point of impact at 7 yards and 25 yards with 230gr ball ammunition.
FWIW, I have run 10-8 .156 notch rear sights with .125 width front sights on full-sized guns and find the .156 is harder for ME to align the sights with when looking for the precision shot ... but it does provide great speed. I am 40+ years old and some reading glasses are in my near future but still find the .156 too wide of an opening for my personal taste on a full-size gun. However, I also run a .156 rear sight with a .125 width front sight on a Glock 26 and find it to be a very good set-up ... the difference being the shorter sight radius (vs. a Glock 21) which causes the front sight to take up more visual space in the rear notch on a Glock 26.
Overall, the .140 rear sight, .215 height/.125 width front sight combination provides ME outstanding accuracy and good speed for front sight pick-up and sight alignment on the Glock 21.
Of course, your mileage may vary.

This is my go to rear sight. I have a 10-8 rear sight on every pistol I own for which they are available. I know of no better statement about how much I like this sight. It offers me a great sight picture when I combine it with either a front night sight or gold dot front sight. My last one was purchased for my SIRT pistol just to train with the same sight picture.

I was on the fence with Trijicon HDs and 10-8s for my g17. I recently tried the HDs on a buddy's g19 and I'm glad I chose 10-8. I went with the .140 rear notch width/.115 front width and its the perfect blend of speed and precision for me.

I ordered the .140 rear for my G17 and paired it with the 10-8 tritium front. I have never had a more accurate and crisp sight picture than 10-8's. The .140 with the .125 tritium front is a great balance of speed and accuracy. These are my third sets of 10-8's and I have noticed that the quality on each set are perfectly consistent. There are no deformities in the sight picture whatsoever. They're simple, rugged, and to the point. Go 10-8.

The u notch makes for a super fast sight acquisition and the cleanest sight picture available. A round fo front fits so naturally in a u notched rear it just performs flawlessly

Rear sight is awesome. The .156 notch is perfect for quick sight acquisition. I paired it with a .125 wide front fiber optic (next time I might opt for the .115 wide). Perfect fit - no filing required at least with my gen 4 g19. Easy to install. The ledge is perfect for one handed manipulation drills.

Excellent quality sight. Fit and finish are great. Easily installed, however did need to use a non-standard sight tool on the Glock, as it was slightly too tall for the factory Glock sight tool.

Love these sights. Perfect combo with the brass bead front. Easy to install. Highly recommended

At 51, it is hard at times to get a quality sight picture. My eyes are not what they were, but the combination of 10-8's .156 rear sight and .235 front for my Glock 34 is a winning combination! the front sight pops! now, and the U shaped rear draws your eye right to the front sight for quick, accurate sight alignment!
You can't go wrong with 10-8 sights!
