Product Description

Our rear sight for the M&P is precision CNC machined from heat treated 4140 bar stock, and are designed to withstand the rigors of hard duty use. The sight features a U notch for fast alignment with tritium, bead, or 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 tritium vials as dots or bars if one so chooses, and is contoured and dehorned for comfortable handling and carry. Finished in black salt bath nitrocarburizing, equivalent to the factory finish on the slide, for superior hardness and corrosion resistance.

  • FITS: ALL calibers, all sizes of M&P, including Pro and 9L long slides
    • Not for S&W M&P .22

The rear sight fits all calibers and all sizes of the M&P series, and is compatible in height with the factory front sight (.160" tall x .140" wide).  Rear sight height is identical to the factory sight, and will not change point of impact. User installation instructions included. This sight will NOT fit S&W 1911 or "Third Gen" (3913, 5906, etc) series pistols.

**These sights are too wide to correctly fit the Shield.  We have dedicated sights for the Shield.

***These sights do NOT fit the M&P CORE series pistols.

  1. Happy, Happy

    Posted by JAA on 11th Aug 2014

    Perfect black rear sight. I prefer the true U shape of the notch vs. the "flat bottom" U with 90 degree angles. The .140 is perfect for my M&P full size 9 when pair with the FO front sight. Shot my first IDPA match with them and my score was better...had to be the sights because I hadn't been practicing.

  2. great sights!

    Love these sights . I've used 5 sets on my M&P's. They are perfect for older eyes. They have helped my shooting . I shoot better with these sights than any others I've tried .

  3. What more do you need?

    Posted by David Burgess on 19th Jun 2014

    In regards to blacked out rear sights, what more do you really need? No glare and the U notch is simple and easy to pick up. Decent ledge to rack the slide on whatever you want. The only thing I would change would be to have a steeper ledge but that's just me trying to find something. There is nothing else on the market like it at all. To put it simply, I now only buy firearms that these sights are available for. Would love to see some sights for the Glocks come back in stock again!

  4. Love the black with no dots!

    Posted by Mike B. on 25th May 2014

    Bought these for my M&P45 FS. Watched the install video so that made me buy the EZE-LAP diamond files from amazon. I did try a regular file just to see if it would work but like 10-8 says the sights are hard. Get the diamond files. Used these to do a little fitting which made installing without damaging the sight.
    I also bought the 10-8 front fiber optic sight which I really love!
    I use the red fiber.

    To install the sights I used the MGW sight pusher for the M&P front & rear sights. This pusher is made like a tank and made the job easy.

    Like I say I love these sights!!

  5. .140 on M&P 9c

    Posted by D Windham on 3rd Apr 2014

    The shipping time was great! I ordered a mag release from another company at the same time and it took an additional week.

    The install was quick and easy.

    This sight really clears up the sight picture and draws your eye where it needs to be, the front sight.

    I plan on ordering base pads for all my Pro model's magazines as well as the fiber optic front for my 9c when the correct size is back in stock.

    Great product and a great company.

  6. M&P45 Rear Sight Install

    Posted by Joe Z. on 21st Mar 2014

    This install on my first M&P went without a hitch. The machining and finish are top notch, without a doubt. Though very tight initial trial fit, a quality file and correct technique allowed me to fit the sight perfectly. Do not rush, and don't use cheap files. The metal used in these sights require good tools. The perfectly shaped "U" notch allows the front sight to be found quickly and alignment is natural. Quality matches their Glock and 1911 sights.

  7. Great Sight!!

    Posted by Bob W on 20th Mar 2014

    Easy install.Clear uncluttered sight picture. Hate 3 dot sights.

  8. M&P .40 Rear .140 notch

    Posted by Jeff on 25th Feb 2014

    Installation was easy. Better/faster sight picture than factory tritium 3-dot. PoA/PoI is right on at 25.

  9. Great product.

    I paired the blackout rear with the red fiber optic front and it is night and day difference over the factory sights. The blacked out rear allows the fiber optic front to draw my attention without being distracted by the rear dots. The rounded off edges on the rear are also awesome when carrying in the appendix position whenever you have a little bit of a belly, The factory sights used to rub me raw, no such problem with these. I recommend to anyone with tired eyes or looking for a more comfortable solution.

  10. Excellent sights! Amazing customer service!

    10-8 Delivers.
    These guys are the real deal. I ordered several sets of rear sights and front fiber optic sights for my M&P pistols a few weeks ago. I fitted and installed them but ran across one rear sight that fit somewhat loose (which i did confirm to be a slightly oversized dovetail slot on the pistol). I like a little bit of an oversized sight so that I am able to fit the sight and get a nice snug fit so I called up the 10-8 team. Not only did they respond very quickly to my emails, but they sent me out a new peaned sight at no charge. Received the sight a few days later...fitted the sight and it installed perfectly. I like a blacked out rear sight coupled with a red fiber optic front sight, and these are perfect.... Absolutely love them!
