Product Description

S&W M&P Dovetail Front Sight, Fiber Optic, for all M&P models.

Our front sights are made from hardened 4140 bar stock for improved durability. Dovetail base is oversized for fitting, in order to accommodate the wide variation in production dimensions.  Blade face is serrated 40lpi. 

  • Fits: ALL M&P models, all sizes, all centerfire calibers
    • Not for the M&P22 pistol
    • Also fits M&P Shield
    • Listed heights are the same as the factory front sights
  • Height:
    • .160" for Compact, Mid Size, Full Size models in all centerfire calibers; M&P Shield 9/.40
      • Factory front is .160" tall
    • .180" for 9L long slide, Pro Series Long Slide
      • **Please note that many long slides shoot a little low and we are recommending that they be used with a .160" front.  We suggest that you shoot your long slide M&P with the factory .180" front in place and see where it prints prior to ordering a new front sight.

Finished in black salt bath nitrocarburizing, equivalent to the factory finish on the slide, for superior hardness and corrosion resistance.

Fiber optic rod is .060" diameter, with .075" flared head diameter on blade face, comes with 1 each red and green fiber rods, not installed.  


***DUE TO THE WIDE VARIATION IN M&P DOVETAIL SIZES, OUR SIGHTS ARE OVERSIZED AND WILL REQUIRE SOME FITTING.  The sights are finished in black salt bath nitrocarburizing, which produces a hard surface finish similar to the factory slide, and will not respond to a normal file.  We suggest using a diamond hone or file.  If you are not familiar with how to properly fit and install a dovetail sight, we suggest that you seek the services of a *qualified* gunsmith.  We are not liable for damage to the sights resulting from improper installation.

  1. Excellent product 5 Star Review

    Posted by on 28th Mar 2018

    This is the second front sight I have bought. Install is easy and I like the fact that the fiber optic rod is also supported in the middle to cut down on flex of the rod itself. I will be buying another.

  2. Great design but be careful 4 Star Review

    Posted by on 18th Jan 2017

    Great design but be careful. I put a set of these sites on to other my pistols and love them . If you are doing it yourself never did it before watch some videos first and take your time. You will need some kind of diamond file as the steel is incredibly hard. Be careful when knocking the site in. My punch slipped and the fiber optic cage crumbled. I had to buy a replacement.

  3. Excellent 5 Star Review

    Posted by on 8th Oct 2016

    This is an excellent FO front sight for the M&P. It does take a bit of fitting by using a diamond lap file on the bottom only. I did use a dremel on the rear 10-8 sight as i needed to remove a substantial amount of material before I could use the lap file to finish it up. This took several tries but once I got it about 1/2 into the front dovetail it was stiff but doable fit. I ended up using a screwdrive the same size as the dovetail, wrapped in 3 layers of electrical tape to tap on the bottom section of the sight. Even after getting it to easily slide about 1/2 way, it still took stiff taps to get it centered. The end result of taking my time and using the lap file resulted in no damage to the slide or sight and a really top notch end result.

  4. Fits M&P Pro 5" 9mm 5 Star Review

    Tight fit but no filing necessary. Went in without issue.

  5. Excellent front sight 5 Star Review

    Posted by on 26th Jun 2016

    I'm running the .115 wide front with the .140 wide rear and these are my favorite after trying both trijicon and ameriglos. This front sight is really easy to pick up and the narrower width covers less of the target. Top notch products as one would expect from the folks at 10-8 performance.

  6. Dead Nuts On 5 Star Review

    Posted by on 20th May 2016

    These sights are dead nuts on for my M&P full size 45 auto. What more could one ask for? Top Shelf, buy without hesitation.

  9. M&P Shield sights 5 Star Review

    Posted by on 14th Mar 2016

    Excellent sights. Bought both front and rear sights to the specs recommend by 10-8 performance. Had them installed so I didn't risk messing up the installation. Could not be happier. Although I had mastered the orginal sights on the firearm after some trial and error these put me on target immediately and with a much better sight picture.

  10. Quality Fiber Optic Front Sight 5 Star Review

    Posted by on 22nd Jan 2016

    I bought and installed this front fiber optic sight for my M&P 9c. It was easy to instal after taking off a little of the coating and metal on the bottom. I used my Dremel tool very carefully and removed a tiny amount each time until I could push the sight in with my fingers about 1/4 to 1/3 of the way. I used the nylon tip on my small hammer to seat it most of the way, hitting only the very bottom of the sight. I then used a delrin "punch" to center the sight. It took me two tries to install the red fiber pin correctly(takes very little heat).
    Perfection! It is bright(.125 size sight) and a tremendous improvement over the factory sight. High quality part!
