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. Best of the best 5 Star Review

    Top shelf products. Buy with confidence.

  2. Anther Great Product From 10-8! 5 Star Review

    Posted by on 16th Mar 2016

    This set of rear sights are the best I've been behind! No glare, fast acquisition when paired with 10-8 fiber optic front sight. 10-8 even took conceal carrying into account and not only rounded the sides, but also they matched the angle on the slide to keep from digging in. I WILL order more of the exact same!

  3. Best rear sight for M&P 5 Star Review

    Posted by on 22nd Jan 2016

    I bought the .140 size rear sight for my 9c. Installing it was not difficult, but I used my Dremel to remove coating and metal from the bottom of the sight a little at a time until the sight went in 1/3 of the way. A delrin punch was used to center the sight after I used some cold bluing liquid on the bare metal, let it dry and smeared with gun oil to stop further bluing action. I put a tiny bit of "blue" thread locker(removable) on the locking screw before putting it in tight(this was done after I sighted the gun in at 30 feet.
    Best rear sight I have seen on any M&P pistol. The .140 notch is perfect(for me) with the .125 front fiber optic 10-8 sight. POA equals POI at 30 feet.

  4. Difficult to Fit 3 Star Review

    Posted by on 11th Aug 2015

    Good site used with M&T factory front on the M&P Pro (Long Slide). Had a lot of trouble fitting the sight, in fact when I e-mailed the company for assistance, never received a reply.

    One sight later figured it out

  5. Awesome, but tough to install 5 Star Review

    Posted by on 13th Jul 2015

    These sights are awesome, I have put them on every handgun that they make them for that I own. 1st M&P, ordered a set. matched up with factory night sight and looked like they would be a perfect fit and match. Nope. Got half way installed and sight pusher slipped and marred the rear sight badly. I didn't think I was putting that much pressure on the push but was wrong. Had to use a metal punch to drift it back out. Ordered a new set. Will be sure i file sight down to slide at least 1/3 of the way next time. Still the best sight out there!

  6. Not the easiest, but worth the effort 5 Star Review

    Posted by on 19th Apr 2015

    Would choose 4.5 but that wasn't an option. The quality of these sights is undeniable. The finish is tough, effective and attractive. But man does that finish make it hard to file. The installation video, although good was not an accurate representation of the amount of filing that is required. Needless to say, I spent hours filing the rear sight in order to make it fit. When I was finished, I could see bare metal from either side of the dovetail, when looking at the sight from the muzzle. These sights are a tool and my firearm is not a safe queen, but it would have be nice to not have shiny metal there. That's the only negative. I like the U notch, have the .140. If I could do it all over again, I think I would maybe try the .125. If you guys ever make sights for CZs (hint, hint) I would probably give those a try. In all, if you're debating getting these, give them a shot. They aren't too expensive and with a set of files from a hardware store, you can fit these yourself, just as I did.

  7. 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

  8. 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.

  9. 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.

  10. 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.
