Really only two options: either send the slide out to have it custom milled (a lot of shops offer this service), or get a M&P CORE slide, which is already milled for red dot sights.

ETA: disregard this post. I misread what you were looking for. Sorry.

Have you checked with Burris for a mount?

I donít know if this applies to the OP, but pleaseó

Donít ďtry outĒ the red dot concept by finding the cheapest way to mount the cheapest red dot and then see if you like it. You wonít, so donít bother.

A properly set up red dot sight on a quality pistol is a new way to aim and shoot. It is a joy to use after a fairly short learning curve if you are already a decent, consistent shooter.

If you degrade any of the components of a proper set up, what you get will be harder to learn to use, less adaptable and more frustrating. This is truly one of those technologies that does not have a low end entry point that works.

Iím all for people doing what they want and spending their budget as they see fit. However, I dislike budget minded folks expecting to get top tier performance from a tier four investment and without understanding what they are missing.

The best way is to find someone with a proper RDS set up and shoot that gun. Youíll like it.

There are RDS mounts that use the dovetail for the rear site. These tend to be specific to the RDS (i.e. Trijicon, Burris, Vortex). At least, they don't require machining.

Well, I may or may not understand your question and my answer coincides, sort of, with another.

If you have an M&P Core, use the correct baseplate that comes with it from the factory. If you don't have a core and thus need to have the slide milled. Have it milled for the specific red dot you intend to use. In that case (a slide that needs to be milled for a specific red dot), no adapter will be or should be required.

Sight Mount Home

I have used this mount on both my Shield and my Full size. Rear sight dovetail same size.

If you do not have a CORE, you can use the existing dovetail with no milling needed. One example is here:

FastFire™ Mounts | Burris Optics

You lose your rear site.

I used the dovetail mount from Outer Impact on my 5" M&P 2.0. It accepts many different red dot sights. Has worked great for me so far, with a Vortex Venom. It's not quite as nice as my Sig's that have the slides factory milled for a red dot, since it sits up higher. That impacts the point of impact a little more at varying ranges.

I may end up getting the slide milled at some point. I just hate to invalidate the lifetime warranty by doing that. And for a range gun, the Outer Impact mount works fine.

I'll second the Outer Impact mounts. I have them on several different pistols and have had no issues. Their mounts will work with most of the popular miniature red dots.
My 5" M&P with a Trijicon RMR mounted and my MK IV Hunter with a Burris Fast Fire 2.

If you do not have the CORE Model M&P, check out the Carver Custom Red Dot Sight Mount.

Adding all that framework that attaches to the bottom, to accommodate a sight on top seems too cumbersome for me....

This is the kind of cheaper compromise to which I referred in my earlier post. It will achieve the goal of mounting a RDS. It will not yield maximum effectiveness of the potential of the RDS system.

Kind of like putting undersized wheels and tires on your carófor show, not go.

Another vote for the Outer Impact system. I've got their mounts on a M&P, two Ruger 22s,and S&W Victory. Mounted FF2, FF3, Vortex Venom and Vipers. They also fit C-more etc. All on the same base.

I'm still on the hunt for a C.O.R.E. slide, but in the meantime, after looking closely at the Outer Impact mount, I decided on the ADE Advanced Optics Red Dot Mounting Plate.





You order the corresponding mount for the M&P, and remove the rear sight. A mounting dovetail slips snugly into the sight dovetail, and you secure the RDS to the mount. Takes about 5 minutes at most.

I chose it over the Outer Impact for two reasons: first, it's concave, so it sits more securely on the top of the slide. From the side, it looks like a "thicker" mount, but because it's concave, it actually sits as low or lower on the slide than the Outer Impact. Second, it has four "locator pins" on the mount, and the Outer Impact uses just two.





When you look at the "thickness" of the mount, make sure you measure from the top of the slide.








Not perfect, and the hunt for a slide goes on, but for $20, it's a surprisingly good (and stout) mount, and it'll do for now.

I haven't seen only the slide for sale (unless you find one on ebay), but I did buy a Ported CORE slide kit for about $350. Assembled slide, ported 5" barrel, rds plates, and CORE backstraps. The slide has the suppressor height sites and the "improved" striker block.

I topped mine with an RM06

I've seen (and missed) a couple, on the "other" site, as well as some others. I keep looking.


I've seen a lot of the ported CORE slides, but I don't want the ports.


On the hunt...

Helpful advantages (among others) of a complete RDS system include:

1. Iron sights, elevated to co-witness (20-25% in bottom of window) with the dot through the RDS. Fastest learning curve to use aligned irons as you have always done to “find the dot”. Lack of iron sights = dot only focus. Learning curve longer and harder. No backup sighting system if RDS fails.
2. Lowest mounting of the RDS above the bore as possible (works with #1; easier to sight over a broader range of distances). The higher the RDS, the more difficult it is to use. Your natural pointing will be significantly different than using traditional iron sights. This makes “finding the dot” slower and harder. CORE + plate = extra elevation over milled only slide. Millimeters make a difference. May require even taller irons if using an adapter plate, and thickness is an issue. Screws have less “meat” to grab. Lose-lose.
3. RDS securely mounted with ridges fore & aft, as in a slide milled specifically for that sight. Mounting pins in addition to screws work well also. Screws alone on a mounting plate are the least secure as they are only two shallow points of anchoring, unless the mounting bracket is thick and therefore tall.

Brackets that mount to the rear sight dovetail often eliminate the rear sight, or at least offer only a very compromised and very tall alternative that requires a corresponding tall front sight. If the sight mounts to the bracket with only two screws (not usually the case any more, pins) shearing of the screws under recoil can be a problem.

Check out the EGW dovetail mount. It uses the rear sight dovetail. You will need sight pusher to install this mount but it does not move once installed. It is working great with my Vortex Venom.

Go to Lone Wolf's site. You can have it milled and they'll put the sight on
for less than a hundred dollars.
They did my M&P Shield and I bought a Shield RMS sight from them. They sell the Burris FF too__or send your Burris with your slide. One week turn around is nearly unbeatable. As is their price.
I have my M&P Shield with the milled Shield RMS sight right here on my
desk. Do to our hot weather I have it in a Remora full sweat shield holster.
Now these red dot sights come with different size dots. I choose the 8MOS
for fast SD practice.
I had a Burris FF sight. Great sight. I just like the Shield that is on constantly with no off and on button__no buttons at all and 2-3 year battery life.
Stay safe.

Wow. This price and turn-around seems awesome, so I checked the site. Unfortunately, they only do the Shield, not the full-size M&P. Back to the drawing board for me...
