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.

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? |

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.

Did I get one just slightly out of spec? |

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

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?

Brownells has factory M&P 9C barrels in stock. I just ordered one.
Measurements and range report will be forthcoming. Update 8/10/12- The barrel arrived today. That was fast. I got tired of waiting for Midway to restock the Storm Lake conversion barrel for my M&P 40C. Plus I saved $60 Externally the barrels look identical to the 40C on Page 1. They also measure almost identical. I was worried I'd get a 9MM barrel that was slimmer on the sides of the breech. Using a dial caliper and rounding up I get this, in the same order as the pictures in the original post that started this thread. .40 S&W 0.594 width of breech area 0.565 width of muzzle area 0.842 top of breech to bottom of feed ramp 9MM 0.594 width of breech area 0.565 width of muzzle area 0.842 top of breech to bottom of feed ramp I am experiencing the type of euphoria I get when I buy another gun.  Can't wait to shoot it.   8-16-12 Got to try it today. 75 rounds no issues. I'm no wuss, but the .40 use to hammer my wrist, this thing is a peashooter compared to before. |

Just got my 9mm barrel for my M&P357c today. The first thing I noticed was how similar the sizes are. I am going to crank a couple of rounds off tomorrow to try it out. The only difference in the two barrels I can find are the lips on the top on either side of the loaded chamber indicator. The 9mm version seems ever so much smaller. Good news is that when the slide is actually on the weapon and the barrel is in the locked possition it does not wobble from side to side. Kind of weird it is a tad bit smaller anyway. I also picked up 3 mags, 2 fs, and once c mag. I intend to get another c and put a +2 extention on it to make the weapon more of the size of my 45c which fits my hand perfectly without any fingers slipping off.

Just took my M&P 357c out into the forest and cranked off some rounds with the factory 9mm barrel. Worked great! The thing definitly shoots very very flat. A lot less snappy than the 357 or even the 40. I would feel very comfortable carrying the thing with 12+1 in the critical duty I purchased. I am very happy with my purchase.

I'm currently looking to get the pistol and was wondering two things: 1. Where on earth can I find one in stock for a decent price? and 2. Where on earth can I find a 5" 9mm conversion barrel in stock?!! And as far as the 5" 9mm conversion barrel is concerned; how much should I be paying? What's a good price? Thanks all, Never though I'd see the day but I actually sold my Glock to fund this buy

Just adding my experience with the factory 9mm barrel swap in full size M&P 40. The 9mm barrel works great & accuracy at 15 yards was as good if not better then the 40s&w barrel. I have some 9mm magazines but I did load a couple 40s&w mags with 9mm and they functioned fine as well. Also having never shot 9mm before in a M&P I had a good laugh on how soft shooting the gun was compared to 40s&w.

Just got a 9mm barrel in for my .40 from Midwayusa. After using my buddies 9mm Talo barrel in my .40 I had to get one.
Looks like I got the older generation of barrel, but hopefully it'll shoot fine.

If you look at the stock M&P barrels, at the muzzle end, there is a "hump" on the barrel that rides in the barrel hole in the slide. This aids in lock-up. If you cut a stock barrel down, then the hump is gone and the fit is kinda sloppy. |

So using either 9mm or 357 in the M&P40 FS model is gtg?
Could I possibly encounter any issues interchanging the barrels w/ an Apex DCAEK? I'm hoping to carry in 357 but train/target shoot in 9mm. |

Took my 9mm barrel to the range today. Used Tula, WWB, Federal and UMC. Functioned flawlessly with all. First 130 rounds were all low left. Next 200 were pretty much dead on. Couldn't be happier.
