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. 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.

  2. 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.

  3. great rear sight 5 Star Review

    Posted by on 1st May 2015

    I've been sold on 10-8 sights for a while. I have them on both my M&Ps, and my TRP, and love them. I went with a .140 rear, and paired it with a .115 fiber optic front. Great pair, with fast acquisition. The finish it great, and well built. I didn't have the tools around to install them, but my local smith said they went on without issue. Yet again, 10-8 didn't disappoint,and offered a much better alternative to the glow in the dark factory 45C sights, at a very reasonable price.

  4. Great sight! Love the U-Notch! 5 Star Review

    Posted by on 29th Apr 2015

    One of the best sight pictures out there. Solid piece and very little fitting required. Had to file/shave just a little of the slide to get the dovetail fit nice and tight on my VP9. Matched up with the 10-8 front sight and it's one of the best aftermarket sights available in my opinion.

  5. HK U-notch rear sights - PERFECT 5 Star Review

    Posted by on 4th Mar 2015

    Great upgrade for my VP9. I also have this on my P30L. Very simple, elegant, and functional. I like having the blackout U-notch rear sight on all my pistols. Installation was pretty straightforward and required only minimal fitting.

  6. best rear sight for HKs 5 Star Review

    Posted by on 5th Feb 2015

    Waited a long time for the rear sights to come back in stock. Went with the .140 rear notch width to pair with my Dawson FO front sights at .130 width. Works like a charm.

    Expect to file a bit with a diamond file you can pick up from Home Depot.

  7. The Perfect Rear Sight 5 Star Review

    Posted by on 21st Jul 2014

    I run a 10-8 rear on all my pistols. Absolutely incredible quality and sight picture. Highly recommended.

  8. Perfect press-fit in P30 5 Star Review

    Posted by on 3rd Mar 2014

    Fit and finish were excellent. The rear sight I received was perfectly sized to tap securely into place on my P30 without requiring fitting or excessive force. Sight picture is excellent. Top-notch product.

  9. Hk45ct 5 Star Review

    Posted by on 8th Feb 2014

    Easily dropped in on my hk45ct. Elevation was unaffected and mine came with mepro light night sights. Only wish the u notch was a little deeper. It just barely allows for the front dot to be in full view. Still a good sight. The rear serrations really make the front sight pop

  10. buy it now 5 Star Review

    Posted by on 4th Jan 2014

    Recently put this on my personal HK45 and a rental P30 for the range. It makes a Huuuuge difference. It's the only way to fly for the newest gen of H&K pistols. Three dot sights are too confusing for our newer students and they all prefer the u-notch rear when shooting with both eyes open. Thanks to the 10-8 crew for filling in the gaps in the industry.
