Product Description

*****Please note that S&W slide dovetails vary wildly from gun to gun, and filing with a diamond file or hone may be necessary for proper installation. Our sights are all the same size (and have been the same dimensions for years), and while they are intended to fit snugly in most slides, the same sight may slide through a particular slide or be too tight to start into another. We can't control the slide dimensions, all we can do is keep our sights a constant size. We are not liable for destruction/damage to sights during installation.

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.

****The left front of the sight has a small angle machined into it. This is for easier installation, and is not a machining error. We know the S&W Armorer Manual specifies that the sights go in/out from the right, but that is for their factory sights. Ours can go in/out from either side, as shown in our video.

  1. Hard to fit 1 Star Review

    Posted by on 7th Mar 2015

    Not worth trying to do yourself.Sights are hard to file.Dinged up sights and slide.If you buy get a sight pusher

  2. S&W M&P Rear Sight 3 Star Review

    Posted by on 21st Jan 2015

    I found the rear sight to be a bit on the full side. I had to stone the sight bottom considerably to get a proper fit.

  3. Replaced stock Rear Sight on Full Size M&P 9mm / 4.25" 5 Star Review

    Posted by on 12th Jan 2015

    Excellent Rear Sight replacement and even better when paired with the 10-8 Performance Fiber Optic Front Sight. Wide rear notch made it quick to pick up the Front Sight in good light and even at dusk. Cut my split times way down over the stock sight that I had blacked out the white dots. Will now be looking to replace the Rear Sights on all of my other M&P Pistols with this Sight - it's that good.

    Did require a bit of filing, but ensured a good tight fit. Easy to file - just need a small diamond stone or a diamond coated sanding stick and some patience. Stop frequently and check the fit until the Rear Sight slides in 1/3rd of the way. Then a brass punch and good hammer slid the Rear Sight right into place. Piece of cake on the installation. Very pleased.

  4. Required lots of filing and brute force to install 2 Star Review

    Posted by on 25th Dec 2014

    Filed the dovetails, lined it up perfectly, drifted it in about half way, and then it would not go any further. Tried to remove, but it was stuck and required a steel punch to remove, which dinged and marred the sight substantially. Once removed, filed some more, attempted to install again and had the same problem. By the time I got this sight installed, it looked like it had been beaten by a cave man. This is not my first go-round installing rear sights, and these were by far the most difficult.

  5. When you want the very best, head to 10-8 Performance 5 Star Review

    These sights are above excellent worthy of any combat handgun. Special Thanks to Donna for all her help and fast shipping. Spend your money here without hesitation, all their products are top shelf.

  6. Love these sights 5 Star Review

    Posted by on 22nd Nov 2014

    These sights were exactly what I was hoping they would be and exactly what I wanted. The flat black "louvered" design virtually eliminates glare and the wide "U" channel makes for rapid target acquisition. Eliminating the 2 white dots on the rear sight of my M&P 45c really makes focusing on the front sight and getting on target much easier. This is my second set.

  7. M&P .115 rear sight 4 Star Review

    Posted by on 20th Nov 2014

    I just installed the .115 rear sight (coupled with a .115 front sight) on a 4.25 M&P based on a recommendation from Frank Proctor. I have to say I really like this set up. I normally run a .140 rear and a .100 front on my 5 inch guns. I'll give them a good run for a while before I make a final decision on this set up. The sight itself is like all the other 10-8 sights I have used...well designed, well made and well executed. They take a little time to fit, but the result is well worth it.

  8. This is a great sight 5 Star Review

    Posted by on 11th Nov 2014

    This sight is exactly what I was looking for. The wide gap makes rapid target acquisition very easy and the flat surface eliminates any glare. I couldn't believe how much better I shot my M&P 45c the very first time I shot after installing the sight.

  9. perfect 5 Star Review

    Posted by on 17th Oct 2014

    10-8 blacked out rear sights are the best. I will only use them for all carry guns from now on. I have the Redback 1/10-8 sights on 2 of my Glock's which lead me to buy this. 10-8 from here on out.

  10. Brilliant! Quicker to pick up sights, see target, and more easy to air accurately align 5 Star Review

    Posted by on 11th Sep 2014

    A wide rear sight combined with a slim front fiber optic sight provides the fastest sight picture possible. The extra room to the bottom provided by the notch allows much faster (the more you practice, the faster you get) sight and target acquisition and more leeway while moving to or tracking new targets.

    Well made, strong finish, ideally serrated, and factory height for ease of matching the front sight.
