I ended up with one that I don't need now. After getting involved in this thread I ordered a factory M&P9c barrel for my M&P40c that was back ordered till around mid March. Well about two weeks later I just bit the bullet and bought a new M&P9c. I e-mailed Midway and asked if I could cancel my order and they said yes and canceled it. About a week ago I get an e-mail saying the barrel shipped. So I e-mailed the girl back who had canceled my order and said that it really didn't ship and was just a mistake, I returned an e-mail saying sorry for the trouble. A couple of days later my wife calls me at work and asks "why I'm buying more shit for my guns" I get home and it's a new barrel for an M&P9c. I e-mailed Midway and they apoligised and said I can just return it.
Sorry, double post.
The full size barrels are back in stock at Brownells.

they are back up at midway too
I did have a 357 SIG barrel and it worked great but the ammo is to costly so I sold the 357 and bought the 9MM instead....much cheaper.
Today my M&P9 barrel showed up from Midway and hopefully will try it out tomorrow in my M&P40.
These M&P's are so modular...thanks S&W.
can you run a full size in a compact frame

Man I wish you kept it and emailed me, I would have bought it and gave you a profit, they are sold out again at midway, I didn't catch this thread... :(
Got the 9mm barrel from midway and I am just trying to install it in my 40.
The barrel is too wide at the muzzle to fit in the slide. Any fix? or did S&W figure out how to beat us?

Hmm....that's a new wrinkle.
Can you measure the width of the muzzle?

I don't have any calipers. I will see if I can try and get by the hardware store today.

Ok Got some measurements.
Original 40 barrel at the muzzle 0.565"
9mm Barrel at the muzzle 0.572"
Muzzle hole in the slide 0.570"
Is the 9mm barrel's coating too thick?
Are my original slide and barrel within spec?
I have a M&P 9 FS and 40 FS. I purchased the 9 in February and the 40 3 days ago, both new. The 9 barrel fits in the 40 no problem and i can rack the slide and seems to be a very good fit, while completely returning to battery. I have not tried firing it in this configuration so something may be out of spec, but I thought I would share since both are from factory.

What's the width of your 9mm barrel at the muzzle? Did I get one just slightly out of spec?
Im sorry I do not own calipers. . . Can you even get yours in the slide?

No, the muzzle end of the barrel is too large, it won't go in.

Here is what I am experiencing!
From what i can see there is definitely a ridge starting 1/2 and inch or so from the muzzle that is more pronounced in your barrel than in my 9mm. I would send it back to midway. My guns are more new so i assume they have relatively new barrels that would reflect current factory standards (even though my 9mm front dovetail is out of spec

). Of course I am just speculating

When I get a chance tomorrow, I'll measure mine.
my 9mm M&Pc measures .568
So I don't know whether this was a good idea or not, but I decided to grind down the finish on the barrel.
It now fits well and hand cycles perfectly.
Is it safe to shoot?
Do I need to put some kind of finish on the barrel or just take care of it to make sure it doesn't rust?

You will probably be okay shooting it. Put some touch up bluing on there to protect the metal.
This thread pretty well forced me to buy an M&P 40 Pro...thanks a ton...

I bought a factory 9mm barrel from midway. My .40 mags will cycle all 9mm rounds without any problems. I did get some dedicated 9mm mags anyways.
Will a 40 slide, barrel and recoil spring fit onto a 9mm frame and function the same? Curious if all M&P 9/40 lower assemblies are the same. . .

Yes they are the same.
