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

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.

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.

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.

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

Another sight for the shop.

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

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

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.
