Product Description

The 10-8 Performance rear sight is precision CNC machined from heat treated 4140 bar stock to better resist the nicking and denting that is typical with the wear and tear of daily carry. All 10-8 sights feature a U notch for rapid, intuitive alignment with a dot front sights such as on tritium insert, bead, and fiber optic front sights. The rear face is serrated at 40 lpi to reduce glare in varied lighting conditions.  The sight blade is thick enough to allow setting in tritium vials as dots or bars if one so chooses, but we recommend leaving them without inserts in order to draw the eye toward the front sight.  The sight body is contoured and dehorned for comfortable handling and carry.  All rear sights feature a plain black blade finished in QPQ/Melonite similar to the finish on the slide. **This QPQ/Melonite finish is harder than a normal steel file, and needs to be filed with a diamond file or hone (see Brownells.com), as files will slide right off the surface.

  • Fits: HK45, HK45c, all P30 variants, VP9
  • U Notch: .140" or .156" wide x .125" deep 
  • Sight is the same height as the factory unit and will not affect point of aim
    • .270" tall rear blade, directly compatible with the existing front sight (factory front is .140" wide x .155" tall)
    • XS front sights are approximately .145" wide x .205" tall and will shoot low with our rear if using a normal sight picture

User installable with hand tools only. 

This sight DOES NOT FIT nor can it be made to fit HK USP, P2000 series, P7, etc. pistols.

  1. Great replacement for factory rear on VP9 5 Star Review

    Posted by on 5th Feb 2019

    In my opinion this is a great replacement for the factory rear sight on a VP9. I used this to replace the rear sight because I did not like the 3-dot sight picture and prefer a blacked out rear sight. Works very well with factory front still installed, and provides POA/POI. In the future I will likely get the fiber optic front sight and install that as well, but for now the 10-8 U-notch rear with the factory front works well. This rear sight also provides a ledge for one-handed racking of the slide which is a big improvement over the factory rear.

    Install was easy enough using a hammer and punch, no sight pusher needed. Just go slow, take your time, and use a diamond stone to file off small amounts of material for proper fit.

  2. HK P30 .140 U-notch rear with factory front 5 Star Review

    Posted by on 22nd Jul 2018

    I chose to use the .140 U-notch rear sight paired with the existing factory phosphorescent front on my 9mm HK P30. I did the installation myself with a big bench vise with padded jaws and it came out perfect in just a few minutes of work... no sweat!

    Point of impact is the same on target but the sight picture is much less busy than it was with the factory setup.

    I highly recommend this rear sight for the do it yourselfers out there who are good with tools.

    Large black U notch with hook front works good for me

  4. great service to go with great product 5 Star Review

    Posted by on 1st Jun 2017

    I use this product on my duty gun with the .156 wide sight. I was involved and was issued a new duty gun and immediately ordered a new sight. The folks at 10-8 express shipped a new sight for me which I greatly appreciate. I'm spoiled by these sights and now hate using any other method to use a firearm on duty.

  5. Questionable quality 2 Star Review

    Posted by on 26th Oct 2016

    I bought two of these for my HK45s and the sight picture is nice. However, the quality of the sights leave something to be desired. The serrations on both sight faces were uneven and chipped in places, and blacking was missing on those uneven sections. For the most part, a little flat black spray paint touches it up, but it's disappointing to have to upkeep something that shouldn't need to be repaired out-of-the-box.

  6. My Goto rear sight 5 Star Review

    Posted by on 6th Jun 2016

    When available, I've replaced the rear sights on all of my pistols with the 10-8 sight. It is a crisp and non-glare companion to the 10-8 front sight.

  7. Great Sight 5 Star Review

    Wonderful well built sight. The fiber is very visible.

  8. Great sight. 5 Star Review

    Posted by on 31st Dec 2015

    I have used this sight on two H&Ks. Both are excellent. I find this sight pairs best with the brass bead front sight. Unfortunately, the bead sights have been discontinued for now.

  9. Outstanding sight 5 Star Review

    Posted by on 30th Oct 2015

    This is my first "U" notch rear sight and I'm hooked. Taking those two corners off the bottom really made it easier to focus on the top of the front sight blade.l I got the .140" for my VP9 and paired it with the 10-8 beaded front sight. I originally wanted the .150" but I'm glad I got the .140" afterall. I'm hitting 10" steel at 100yds and cleaning the pie rack in smoking time at 20. Great combination. I've got a .156" from another manufacturer and I'm not as consistent at longer range. Definately recommend.

  10. Near perfect. 5 Star Review

    Posted by on 24th Oct 2015

    This rear sight was easy to install and paired with a Dawson FO front has become my preferred set up. The machining is great and the sight picture is excellent.
