M&P9 Shield Barrel

[OhioLefty]

New Shield 9MM owner, first time poster. Did not know about the barrel swap with the .40, I take it that the .40 barrel can't be swapped into the 9MM? Can anyone explain why? Just curious.

No big deal, I was looking for a reason to get another Shield (.40 this time).

Great bunch of folks here, been lurking for a few days before signing up. I'm glad I did.

The 40 barrel cannot go into the 9 unless you do a little bit of grinding to make it fit. The 9 fits fine in the 40. There is a tiny bit of movement if you push on the barrel but I don't think it is enough to cause an issue?

Thanks, I kinda thought it might be something like that but wanted to be sure.

The 40 barrel into the 9mm slide will work. The following photos show what area on the 40 barrel needs to be reduced, so it will fit into the 9mm slide. You grind the tang, on the 40 barrel, so it will fit into the 9mm slide opening, which is narrower than the 40 slide width opening. The fit is even better than the 9mm barrel swapped into the 40 slide, since by grinding the tang, you make the 40 barrel a perfect fit. There is a little extra side to side play with the 9mm barrel in the 40 slide, as you can see by the photo dimensions. This extra play does not cause any issues in the 40 to 9mm swap, and does not affect accuracy at all. Your width should be similar to mine. The 40 barrel needs to be reduced .026 inch, .013 per side. Then the 40 barrel will drop into the 9mm slide. All else works perfect, recoil springs, extractor, and the ejector. Then all you need are the 40 magazines.

Thanks for the info on modifying the .40 barrel to fit the 9mm Shield. I still haven't found a shield but now I know I can buy either caliber and then switch barrels to have a 2 caliber pistol.

You can't go from a 9 to a .40. The bolt face is too small on a 9mm slide to accept the .40 cartridge.

 

[robkarrob]

Sorry Lost Lake, but the bolt face is the same for both models. There is only .035 inch (1/32 inch or 1/64 inch per side) difference between the diameter of the cartridge rims. The slides are exactly the same except that the width of the slot, where the barrel tang fits. This slot is at the top rear of the bolt face and is narrower on the 9mm slide than on the 40 slide. The slide markings are different (Shield 9 or Shield 40). Everything else is the same, extractor, ejector in the lower housing, recoil springs, etc. 40 into the 9mm will work with just a little metal removal from the tang on the 40 barrel.

I know Midway and Brownells sells barrels and barrel conversions.

Barrels | Smith & Wesson M&P | Semi-Automatic Handguns


It's funny seeing you guys saying you buy from Guns & Gear in Agawam.

I'm local to them and they are my go to store, they are great people there and stand behind what they sell.

It's just funny seeing someone from Florida (or somewhere else) saying that they buy from them...

 

[robkarrob]

Right now the problem is finding anyone that has the barrels in stock. There are many gun suppliers that sell the barrels, but finding any in stock, is the problem. Guns and Gear Outlet was the first to sell Shield barrels. They do not show them on their website. Call them at 413 786-0100 and order. I also know someone that ordered and received the Shield 9mm barrel directly from S&W. The number is 800 331-0852 ext 4125. If you call Smith, don't say a conversion barrel, as they don't sell conversion barrels. Tell them you want a backup barrel or your polishing the stock barrel and want a another barrel if you decide to sell your gun, etc.

Just called S&W for a 9mm Shield barrel and they said they do not sell just the barrels. He said you have to send the gun into them so they can fit it and make sure everything is ok. Sounds like they have caught onto the .40 to 9mm barrel drop in conversions people are doing.

S&W want gun returned for replacement barrel

I just spoke with S&W parts and they would not accept an order for a replacement 9mm shield barrel. I wasn't trying to get a barrel under warranty and told them that. The rep insisted I had to ship the gun to them for proper fitting?!? Sounds like BS to me. In light of all the discussion here I'd say they are onto the the useage for conversions.

If anyone has other sources for 9mm SHield barrels please share.

Thanks

Called today and they didnt want to sell me one. Guy said they are not allowed to sell parts for this gun as per their lawyers.

This has pretty much been the case with everyone who calls S&W in reference to barrel now days. They have finally caught on to what we are doing. You're best chances would be find a 3rd party dealer who may have one or may be able to get one.

Scroll up through the replies on this topis and u will find a place called Guns and Gear that most of us ordered our parts from. You can check with them from time to time and they may put their hands on one. When all of this first started, this was the only place we could find that could put their hands on the parts for us, besides S&W.

Bob, do you know of anyone who done this conversion from 9 to 40? I have a 9, and I was thinking of selling it to buy a 40, but I am having issues finding a 40 in my area.

 

[Oldgoat03]

After reading about them here I called Guns and Gear to order a 9mm barrel for my .40 shield. I was told they were sold out and not taking backorders. They did say they had more barrels coming in but couldn't say when. I was really getting frustrated but then they suggested that I "like" Guns and Gear on Facebook. That way I'd recieve notice as soon as they came in. I did as suggested and had a barrel within a week (early May). My 9mm conversion works perfectly.

Hope this helps

Click the link below to my original .40 to 9mm conversion. We discuss just about everything about the .40 and the 9mm. Page 3 shows a user who converted his 9mm to .40 after we informed him we believed it would work due to everything being the same besides the barrel and the mag. He bought the .40 barrel and converted it to fit his 9mm slide. Keep in mind he modified the .40 barrel NOT his 9mm slide. He had to do this to make the .40 barrel fit the face of the 9mm slide.

In the end the conversion both ways works flawless.

You can't go from a 9 to a .40. The bolt face is too small on a 9mm slide to accept the .40 cartridge.

I have been looking for a 40 pro 5" slide to put on my standard 9 with no luck, like all the other post I'm sure S&W would rather just sell another pistol. I would not want to go through the trouble and expense redoing another sloppy trigger

 

[Fuzzyhead]

I was considering either a Shield 9mm or XDS 9mm. This thread sold me on the Shield .40.

It's the best of both worlds. Small, slim CCW gun in both calibers.

S&W Not selling barrels

I called S&W customer service and they confirmed they don't sell barrels. They said if a barrel is defective they require you to send it in. I said I wanted a back up barrel. He said "we don't sell aftermarket barrels right now".

Guns and Gear were very friendly when I called. They said they haven't received any in 3 months.

Lucky dogs who got them while you could.

I would actually prefer to get the Shield 9mm barrel and modify the .40 barrel to fit it as you could get the slide to fit perfectly. I can't find anyone who has done this though. Everything I've seen has been .40 to 9mm.
