How should I clean an M&P?

On the S&W M&Ps there is a steel chassis inside the polymer grip. So the slide rides on steel rails.

Hoppes gets along with polymer. The slide will mate with metal on the polymer lower. I think once you have it in hand and field strip it, you will see what to do.

I love my M&P 9C.

M&Ps are stainless steel with Melonite surface hardening treatment (similar to Glock's Tenifer process which is not used for models made in the USA).

Similar to cleaning and lubing Glocks, I separate the slide from the frame and remove the barrel/recoil spring assembly to field strip. I use Hoppes #9 solvent/copper bore brush/detail brush to clean the fouling and apply Breakfree CLP on 4 slide rails and the striker release point on the frame. After reassembly, I cycle the slide several times and lock the slide back and apply one drop of Breakfree on top of the barrel where it makes contact with the slide and cycle the slide a few more times. I wipe off any excess lube.

For me, M&Ps have worked well even dirty. I shoot jacketed/plated/lead reloads and if I don't have enough time for a detailed cleaning, I will just clean the barrel/check any fouling build up by the extractor and wipe off any loose fouling with a paper towel and lube before reassembly.

I'll echo "bds."
We have a son who is a LEO, issued 9mm S&W M&P. He, and I, clean it just like bds sez. I reload all types of bullets, too, and usually leave mine dirty, but well lubed. No problems!

Yes, your M&P will have a steel slide running on steel rails. Conversely, your SIG most likely had a steel slide running on aluminum rails.

Here is how Hickok45 cleans an lube's his Glock with Ballistol. It is simply a CLP product, there are a bunch of quality CLPs available. You can use just about anything you want.

Read the section in the M&P owner's manual that pertains to cleaning and lubing the gun. All you need is CLP.

If you're missing a manual you can likely get it here:

Just try not to "overthink" the issue, if you put as much lube on it as you did your "full metal" pistol then you have in all likelyhood exceeded what is "necessary". That will not hurt it or normally cause any functioning issues but it may simply be "overkill".

I am a "1911" guy from many years back and still prefer it and love the design (carried one "on-duty" for many years). About 2 years ago our dept. decided that they needed to dictate exactly what weapons we carried and chose to issue M&P's. The M&P's are fine weapons and are almost "stupid proof", so unless you are putting too much oil in the sear area I don't think you can go wrong.

Sorry, my point is that when we spoke with the S&W rep's they advised that the weapon is designed to be functional with minimal cleaning and with minimal lube, so you almost "can't" screw it up. Don't "overthink" it, just have fun and enjoy it. Good Luck

From experience PoPo22 is right.
M&P like to be lubricated. But do not overdue it! A light spray or the drops as suggested is good enough.

Now if we were talking about the M&P 22 it's a different story. Those need to be welll lubbed.

As you would any other pistol, with solvent and a brush.

Excellent way to get assistance.

Hoppe's is fine on my 40FS and some days I'll grease other days I'll oil, its all good.

I use Hoppes or clp on mine. For clp I like G96 just because of its smell. I put a small drop of oil on each of the four rails and then reassemble.
