Guns and Gear in Agawam MA has them for sale. Whether in stock is another story. Mine should be arriving today
They are hard to get ahold of sometimes though
Another thread mentioned that you may be able to order from S&W directly now for less $$

How much is a 9mm barrel to your door?

Guns and Gear was $75 plus $10 shipping. S&W was $61.00 plus $6.50 shipping.
Just a question of availability. Not always in stock at either location.
Guns & Gear 413 786-0100
S&W 800 331-0852 ext 4125
Don't tell S&W it is for a barrel swap. Make up a story that you want a backup barrel, you want to keep the stock barrel and polish the new barrel, etc. If S&W finds the barrels are being ordered for swaps, they may cut off the sales.
S&W part numbers:
Shield 9mm 42199
Shield 40 42185

I received my barrel from Guns and Gear last week...dropped it in my 40 and performed great! Only meh is the quality the feed ramp...it worked fine though
The feed ramps always seem to have some sort of blemish..that dark spot won't buff out

I have some questions regarding swapping out the barrels and mags for a different caliber, aren't there going to be ejector and extractor issues here? I know you can't do that with a Colt 1911 without having to buy a new slide at the very least.

Have you measured the width of the barrel hoods of the two barrels? A lot of folks trying this in the full size M&Ps have found that 9mm barrels and mags will work, but accuracy will suffer due to side to side play at lockup due to the 9mm barrel hood being narrower. I am one of these people. I now use a proper conversion barrel in my full size .40.
YMMV

They all work fine with no accuracy issues. The extractor and ejector are the same parts in the different calibers guns, so there is no issue with the swap. You must swap model to model: FS 40 with FS 9mm barrel; Compact 40 with Compact 9mm barrel; Shield 40 with Shield 9mm barrel. I have measured the barrels and found the outside dimensions of the barrels are the same, model to model. The only variation is the tang/tab at the top rear of the barrel (at the sight hole). The 9mm tang is slightly more narrow than the tang on the 40 barrel. With the 9mm barrel installed into the 40 slide, there is a little extra side to side play, at the rear of the barrel (very minimal extra movement). Everyone that has made this barrel swap have said this does not affect accuracy. Some have even said they felt they were more accurate with the 9mm barrel installed. It is an inexpensive way to have two different gun calibers, for the price of a barrel.
I did the swap to my Shield 40, to reduce the cost of practice ammo. I use mostly 9mm for practice and shoot a few of my high power SD 40 ammo, to keep me familiar with the higher felt recoil and flip. I always carry my Shield as a 40. I have not had any feeding issues using my 40 magazines to feed the 9mm cartridges. I would suggest using a 9mm magazine, if doing the barrel swap for carry. You don't want to take any unnecessary chances for mis-feeds while carrying. Using the 40 magazine for practice doesn't have a risk factor, only a chance of a mis-feed. I also bought a 9mm magazine, which works perfectly and turns my Shield 40 into the Shield 9.

Thank you for this information! I just back-ordered one with Smith & Wesson. For anyone else who might be placing an order - I was asked what I was going to do with the barrel? As you might suspect, the customer service representative was not very happy to hear I was going to use it for a .40 conversion and further stated "we do not endorse doing that - do not send it back here if something goes wrong."
He was not able to give an estimate on when the backorder might be filled.

Should have asked him why are they selling them then? I mean do people keep spare barrels around of the same caliber just for the hell of it?
Maybe they do..I never have
yes there is very very very minimal play in the barrel if you push on it..but then again the 9 barrel in my FS 9 has a little bit as well
Ive shot 150 rounds, accurate and no issues

Don't say to S&W you are ordering for a barrel conversion. Say you want a back up barrel, you want a barrel to polish and still keep the original, etc. If S&W feels the orders are for barrel swaps, they may put a stop to the barrel sales.
They are never going to tell you it works. They are going to advise against a barrel swap. They want to sell guns, not barrels. There is much more profit in a $450 to 600 gun than in selling a $70 barrel. Their though may be if you don't do a barrel swap, maybe you just might buy another gun.

You mean the 9mm barrel is on back order. Crazy
Hey Rob, i believe we predicted the future a few months back.

For all of you thinking about the barrel swap, you can thank Smitty357, as he tested this back around September +/_. He owned a Shield 40 and a Shield 9mm, and he swapped the 9mm barrel into the 40 slide, and found it worked fine. He has posted several videos regarding the swap, and advised us of Guns and Gear Outlet, where we could purchase the 9mm barrels. We have teased him that he should be getting a percentage of all the 9mm barrel sales.
A number of us have made the swap with our Shields, and when we see someone asking which gun should they buy, a 40 or 9mm, the answer is easy. We say choose 40, as you can order a 9mm barrel and have both for the price of a barrel. So Smitty you have started a trend. And again I thank you for showing us all this easy, drop in conversion.

Yes I know someone that ordered the Shield 9mm barrel from S&W. He got it delivered last week and S&W screwed up and sent him the Compact 9mm barrel. They are sending him the correct Shield 9mm barrel and a return shipper for the wrong barrel. He has not got the correct barrel as of yesterday (Friday 2/8/13).
