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. vp9 5 Star Review

    Posted by on 20th Oct 2019

    Best rear sight for the VP9. This is the 2nd sight I have installed on the VP9. Dovetail cut is perfect with no issues on the installation. Highly recommended !

  2. 4 sets and counting... 5 Star Review

    Posted by on 5th Aug 2019

    I have been shooting handguns with enthusiasm for over 25 years. These are far and away my favorite pistol open sights, and I own them (or will) for every pistol for which they are made. Sights are very personal, and everyone's milage will vary; I find the features on these sights wholly unbeatable for my eyes: finely serrated (on the front, too, this REALLY matters), U-notched, sight radius-maximized, cocking hook on rear, and the front night sight's tritium dot is not too large, bright, or encased in an inexplicably huge and orange surround. The quality of the steel and its treatment really look at home on an HK--and that's saying something. The side of the dovetail even has a slight bevel to ease proper installation (maybe just on the last one I received? Never stop improving?)--no detail appears overlooked. The 10-8 setup allows me to aim very small, and shoot very fast and confidently. For my beloved HKs, there is no better sight for me--so seriously please do not stop producing them for what must be a fairly small market. I would love to have them for the USP and P2000 as well; there is a large demand, I know I want them I never felt my USPs Dawson's were a downgrade until now! You guys should send me a coupon code at this point and I'll get some for the 1911s ;)
    Businesses like you are what makes America great, and American.

  3. Excellent sight 5 Star Review

    Posted by on 2nd Jul 2019

    Installed with no filing needed. The profile of the sight makes centering on the slide easy to verify. Regulated to top edge at 25 yards with Speer Gold Dot 124+p. The U notch provides a pleasing sight picture which makes centering the FS very fast.

  4. 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.

  5. 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

  7. 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.

  8. 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.

  9. 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.

    Wonderful well built sight. The fiber is very visible.
