  • The complete kit: mag well, mag well insert, set screw, wrench.
  • Remove your factory frame insert and replace it with the 10-8 unit.  The stainless steel insert pin (the only shiny silver pin on the frame insert) is bonded in place and will not fall out.

  • DO NOT OVERTIGHTEN the set screw!  The frame and the mag well, both being glass reinforced nylon, are somewhat flexible.  On some frames it is possible to tighten the screw enough that it flexes the frame and keeps the mag from dropping out.  Simply back the screw out a half turn at a time until the mag drops free again.

Product Description

Updated 01/14/2019: LIMITED AVAILABILITY - We have discovered a small overstock quantity of our original M&P mag wells and are offering them for sale at a reduced price with some important caveats and updates:

1) This is NOT compatible with the M&P 2.0 - the frame geometry is completely different than the pre 2.0 models. This is ONLY for the full size 9/40 pre 2.0 models.

2) We originally had to discontinue these because the M&P frames varied so wildly in shape/size that not all customers had the same excellent experience. In order for your purchase to be eligible for return, it must be LIKE NEW. Test fit just the funnel on your frame, and if you like how it fits, then you're good. If not, STOP there and DO NOT install the screw into the locking piece and certainly do not perform a bunch of speed reloads to see how you like it.

3) You may need to lightly sand the interior edges of the funnel to get it to match your frame exactly.

 

 

 

This magazine well is easily installed by the end user with only a hex wrench, and offers significantly improved speed over the stock frame opening.  The funnel is CNC machined from tough glass reinforced nylon – the same material used in our Armorer Block.  This material is comparable in strength to the frame material, and adds negligible weight or bulk.  The use of nylon instead of aluminum gives the magazine well an extremely slick feel during reloading, and was preferred by all beta testers over the aluminum prototypes.  The funnel is firmly anchored to the frame through the use of an included machined aluminum frame locking piece, which replaces the factory plastic locking piece, and does not shift or work loose in rough handling.  This magazine well represents our uncompromising approach to design, and promises to be the highest quality M&P magazine well available on the market.  It is suitable for duty use, competition, and CCW applications.

FITS FULL SIZED M&P 9/40 ONLY. Not intended for the compact (9c, etc) or .45 models. NOT COMPATIBLE WITH M&P 2.0 MODELS.

The magazine well is designed to be compatible with our new XTC base pad.  Due to the way that the magazines seat in the bottom of the M&P and the way our funnel had to attach, it limited what base pads are compatible with it. We only warranty 100% fit with our XTC base pads, as we cannot control the dimensions of competitor's base pads.

Does NOT fit:

  • Original 10-8 aluminum M&P base pads
  • S&W factory base pads, compact base pads, 10 round magazine bases
  • Arredondo molded extensions
  • Apex/10-8 molded base pads

Fits in IDPA box (with XTC base pads), legal for ESP.  Not USPSA Production Legal.

 

**Installation is easy, but look at the photo gallery here for some tips.  DO NOT OVERTIGHTEN the set screw!  The frame and the mag well, both being glass reinforced nylon, are flexible, and the slightest pressure on the frame will cause magazines to bind.  On some frames it is possible to tighten the screw enough that it flexes the frame and keeps the mag from dropping out.  Simply back the screw out a half turn at a time until the mag drops free again. We have to walk a fine line with having the funnel attach tightly to the frame yet exert zero pressure on it.  

**Depending on frame dimensions, it is possible for the interior of the magazine well to fit such that it can interfere with the magazines.

 

Common questions answered:

  • Will you be making this for the .45 M&P? 
    • Unfortunately, demand for .45 M&P accessories is very low as compared to the 9mm, so we have no immediate plans to make a .45 mag well and base pad setup
  • Will you be making these in other materials like aluminum, steel, or brass?  
    • We have prototyped these in aluminum, but all of our beta testers preferred the nylon version to the aluminum, and we think you will too.  
  • Why didn't you make this compatible with your old base pads!  I have a million of them!
    • We tried, and since the M&P mags stop on the bottom of the frame via the base pad, it was not possible to get that to happen with our flat pads and still have a funnel of any value.  
  • Why didn't you make this compatible with the factory base plates!
    • If you look at the bottom of the frame when the magazine is seated, you'll see that there is no room for a funnel of any sort as the magazine base pad occupies the entire bottom face of the frame as that is what stops it from over inserting.

  1. could have been so much more 3 Star Review

    Posted by on 9th May 2016

    I have bought several products for my m&p from 10-8 and was excited to get their Magwell it fit great and was easy to install but I do think that it is slightly ridiculous that it is plastic and is72 dollars with shipping . It feels cheap and make me worried I might break it. I would love to see this product made in metal.


  2. Mag well for M&P40 4 Star Review

    Posted by on 28th Feb 2016

    Lightweight and looks good. Attaches easily. Fit is a little loose on front but not enough to make a difference. That was the only reason for missing star.


  3. Nice finish, perfect size 5 Star Review

    Posted by on 17th Feb 2016

    Great product overall, quality of the design is top notch. The geometry of the seems and overall look of it exceeded my expectations when I put it on. I haven't had any issues whatsoever with mags getting stuck when releasing or not fitting properly. Also, my Taylor Freelance +5 9mm base pads work without having to do any contouring to the magwell or baseplate. The wiggle room in the front is extremely minimal and I only notice it when I deliberately put downward pressure on it. The magwell looks and feels great and I'm glad I bought it.


  4. Perfect Fit! Great quality part! 5 Star Review

    Posted by on 16th Feb 2016

    I see a lot of pissing and moaning about fitment so I want to address it. 10-8 has no control over S&W quality control! If it doesn't fit it's on S&W!!! If it's not what you expected then you should have read the description of the product, just sayin'.

    As for my experience. The magwell was exactly as described, light weight and perfect for concealed carry and general use. I installed it on my CORE within five minutes and the XTC bases on several magazines within another five minutes.

    The fitment was perfect but took a little adjusting on my part to find the sweet spot with screw tension. There is the slightest of movement but it doesn't effect the performance or integrity of the part at all.

    I like the part enough that I plan to do a review on my website and Youtube channel after several thousand rounds. Buy with confidence.


  5. M&P Magwell doesn't fit as secure as I'd of hoped 2 Star Review

    Posted by on 14th Dec 2015

    I've always been a big fan of 10-8 products, and all the other stuff I've bought has been great, but I should have followed other reviews that mentioned the loose fit and average quality. After mounting this magwell to my M&P CORE, when I firmly grab my gun, the front portion of the magwell moves quite a bit. I could probably fill the front space of the magwell with some form of epoxy to fill the void between the front lip of the bottom of my gun. This space between the front magwell and the front lip of my gun is where the majority of the looseness is coming from. The overall fit of the magwell is much too loose in my opinion. I don't want my magwell moving around when I'm gripping my gun. I'm a bit disappointed in this purchase, and I wouldn't have mentioned all this, but you guys sent me an email asking for my review of this recent purchase, so here it is.


  6. like it but i dont 3 Star Review

    Posted by on 11th Dec 2015

    It fit good when I put it on not lose or any thing the bad is that it won't work with taran tactical base pads but u can grind down the back end of the magwell to get it to fit . If this was my product I would make sure it fit most of base pads out in the market it is light and not wide like most magwell witch is good I use it as a carry gun any ways
    Over all I like it wish it was cheeper like 25 to 30 bucks for plastic that u have to grind on to make it fit for base pads


  7. perfect 5 Star Review

    Posted by on 28th Oct 2015

    As you should know the only thing that makes mag changes faster is practice, but this thing makes it much easier. It also serves as a base for your hands which gives you a more comfortable grip and more control.


  8. Excellent 4 Star Review

    Posted by on 26th Oct 2015

    This is a great product! The install was super easy and it fits perfectly. This makes reloads a breeze and looks cool too which is a plus! My only gripe is that the plastic dents very easily. I have had the device for about a week and it looks like its been beat to hell. Device still functions well and I don't really mind the scratches but if that is something that may bother you please be aware.


  9. magwell 4 Star Review

    Posted by on 2nd Oct 2015

    When I received the mag well I was surprised. It was easy to install and fairly slim line . It is a little loose at the front but other wise I was happy with the product . Thanks 10-8 performance


  10. FITS LIKE A GLOVE!!! 5 Star Review

    Posted by on 29th Sep 2015

    I ordered this mag well for my M&P 9L Performance Center, along with the 10-8 magazine base pads, and I couldn't be any happier with the quality and fit on these parts. Mag well took about few minutes to install, and fit absolutely perfect. Love the way this mag well looks on this pistol, I was looking for something little less bulky than some of the other ones on the market, plus this is very light so it doesn't add any more weight to this pistol. I'm super happy with the looks and functionality of this mag well. The magazine base pads are excellent also, fit is absolutely top notch and I like the serrations on the front. Extremely happy with them as well. I would definitely recommend this combo to anyone with an M&P pistol.
