Converted my Shield .40 to 9mm

Check posts 61 and 65. All fits and will work. If 40 into 9 works, the breach face will allow the 9 into 40. The extractor and ejector are the same for both guns.

I fixed my post, I meant 9 to 40.

Great thread guys, I was on the fence of 9 or 40 for the Shield (I have the FS in 9) I picked the 40 and also have a 9mm barrel and mag on the way

It also helped my decision that all they had was the 40 Shield when I went in last night lol

Yep for anyone who is waiting in line for the 9mm, i may go ahead and just purchase the .40. As said before the recoil isnt that big of a difference between them and the dual recoil springs helps tremendously on handling the recoil in the .40. Its not as snappy as most people would think from a .40 in a such a small frame.

I dont think you'll hear any complaints from anyone of us who have converted. It's a cheap and easy conversion and that only takes a minute or so to make work.

Sure we ordered from the same place. Guns and Gear (https://www.gunsandgearoutlet.com/) in Agawam Mass. Ph#(413) 786-0100. I paid $75 for 9mm barrel and 3=$32 or so for 9mm extended magazine

WOW, what a fantastic deal! AMAZING LOW PRICE!

357 Sig can be used in a 40 magazine, all you need is a barrel change. I bought extra 40 magazines and put different colored bases to tell which ammo was in it. It's not a shield, but the same principle. A 357sig case is a necked down 40 case. Same magazine for both.

Not to be a heretic but I've made that same swap (from .40 to 9mm) with both a Glock 27 and Glock 23. With 9mm mags, absolutely no problem. Using Lone Wolf's barrels; and now I can shot lead ammo in the 40 to 9 barrels since the rifling is more conventional. Also more accurate that OE. Only prob that ever arose was trying to cheat with .40 mags and 9mm ammo; function problems common doing that but mostly ok. With all the hoopla over the supposed Glock KaBooming, one might cringe but it's quite a common conversion and never heard of problems.

.40S&W to 9mm

Not only the Shield, but my XDs, Glocks, Sigs and M&Ps which are in .40S&W, all are
in the three barrel flavor........40S&W, 357Sig and 9mm. The secret is that the 9mm barrel must be of the 'bull barrel' size. All of mine function flawlessly. The 9mm mag
must be used with 9mm ammo. Oops.....me forgot about my Keltec. It is all three barrel flavored also!!!!!

Was advised that S&W is now selling both the 9 and 40 Shield barrels. Price is $61 plus $6.50 for shipping Part numbers are 42199 for 9mm and 42185 for 40 S&W. Call 800 331-0852 ext 4125.

I talked to a customer service rep at S&W about the availability of the
9mm barrel. He told me it was on back order(big surprise!)& out of curiosity
I asked him if there was a "conversion kit" for that. He said they didn't offer one &
didn't recommend using the 9mm barrel in the 40C because it would eventually
ruin the slide. Has anybody else heard this?

 

[robkarrob]

They just don't know and make a stupid statement. There is no way the 9mm barrel in the 40 slide is going to ruin anything. They are not going to tell you "sure it works" as they make a lot more profit off a gun than selling a barrel. There have been lots of posts on this Forum saying it works perfectly. If you've been reading some of the many post in this Forum, you would know if there was a problem. It not like we all own stock in a barrel making company and are pushing up the sales.

Don't ask for a conversion barrel. Just say you want to order another barrel, or a backup barrel.

I ordered a 9mm barrel from Guns and Gear on Tuesday. She said it would be shipped out on Wednesday. Cc charged but no barrel yet. I don't mean to sound impatient but I live less than 2 hours way from the place

Hopefully it will come tomorrow but I would have thought it should have taken only a day to reach me. I'm also a little concerned as they posted on Facebook that they are going through some issues with employees and needed to close on Thursday. No answer when calling today either

For those that got the barrel how did it come ? UPS or post office? I'm going to be in the area tomorrow. I may stop in

It does all boil down to how they ship.
USPS would definitely be quicker than UPS. UPS seems to default to 5-7 business days, even when it's right across the street.
How a company ships is definitely one of the things I ask when ordering by phone and I try to opt for USPS.

Has anyone actually done the 40 barrel into the 9mm slide? I just ordered the 40 barrel and mag for my 9mm Shield from S&W. I'll try to document the work and show the results when it's done. Fingers crossed.

Most likely the real reasons are:
1-Wanting to sell you a whole new gun.
2-Liability issues.

I suspect #2 is going to be the main reason because if anything bad did happen, and they "told you" that you could do it, it could easily become an expensive legal nightmare.

Swapping barrels like this constitutes a "design change", and in addition to any of the engineering checks, there are likely to be a lot of expensive qualification testing and approvals needed for it to become an "officially approved" option. Without that, S&W customer service is not going to encourage people to do it, even if they knew there wouldn't be a problem. IMHO-naturally.

Ok guys, I get home tomorrow night and hopefully pick up my .40 on Wednesday. So I just posted in another thread about this 9 to .40 conversion and it got me thinking... Since I don't have a spare .40 barrel yet, I'll just have the one from my Shield, will grinding the tangs a little hurt using the barrel in the original .40? My guess is no because it would essentially just be the same size as the 9 barrel correct? It'll just leave a little gap between the slide correct?

 

[Smitty357]

I'm curious as to why u want u to do it. Im assuming u already have a 9mm Shield and ur about to get a .40 Shield.

Why dont u just do what I do any buy a 9mm barrel for the .40 that u will be getting. And just leave your original Shield 9mm alone. Dont even worry about converting the 9mm one. Just convert your .40 to 9mm with the barrel (since u already have to buy another barrel no matter what), and leave it at that.

 

[robkarrob]

I'm confused also. I thought you had a Shield 9 and were thinking of doing the barrel swap up to a 40. That is why we said it would work in the 9 slide by grinding the tang down on the 40 barrel. Maybe a little more explanation as to what you are planning.

[Dikinalaska]

Sorry to be vague. Yes I have a 9 Shield, but technically it's my girlfriends now. Remember the pink? Lol. So I'm picking up my .40 when I get home. I want to put the .40 barrel in the 9 mostly just to prove it works, but also because in the long run I'll be buying another of each barrel so both me and her can have a 9 & .40. 4 guns for the price of 2 + barrels.

 

[Dikinalaska]

And I'm only home for one week so I won't have time to wait for another barrel to arrive. It's partly that I'm excited to do it so I don't want to wait, and partly because I don't want ti make the community wait any longer for someone to do it and prove it works. Plus after this week off, I'll be back at work for another three weeks so I/you guys would be waiting at least another month for it to happen.
