Barrel Conversion Table

I have read a handful of threads dealing with with caliber pistol will take which caliber barrels, slides, etc. I have a quick little table here that I would like to get your comments and feedback as to accuracy. I can create these for any pistol we would deem necessary and have them available for all us newbies to reference.

Many thanks in advance.

1 APR 2015 – Updated table to reflect recently discovered changes. Many thanks to those who have taken the time to help ensure accuracy.

21 JUL 2016 – Updated table.

Looks good to me. Thanks for compiling!

Wish I had known that when I first got my 239. I called Sig and was told both 357 and 9mm were conversions. I got a Sig 357 that said conversion 357, and a bar-sto 9mm after a reasonable waiting time.
I was told here by Brickhead, they all the same size, so at a range that had a 9mm we put their 9mm barrel in my 239-40. Fit perfectly.

Prey tell where did you get that, and Thanks for posting.

I made the table based on some feedback from MC awhile back when I purchased a P239 Tactical from BDLCOM. I was confused then as to what I could do with it drop in barrel-wise.

What other P-series pistols have this same caliber availability? Also, this applies for drop-in barrels only, or does it also include conversion kits?

dwg13013 · Dec 28, 2013

I had a 229-40/9mm. Also I had a 226-40/357 sold like that from Sig.
I understand the 226,229,and I think the 2022, the 357 - 40 interchange and they all Must use a conversion 9mm bar-sto or Fire dragon Semi-fit.
Both are more accurate than a factory Sig barrel.
I have-had three Bar-stos and am impressed every time I shoot them.
The 40 magazines shoot all three calibers. Both Sig and Glock.

I just got a Bar-sto story CD from Top-gun and it is very informative. On Barstos start in the target shooting of the 70s to all the different ways barrels are made now, and why. Also how to judge and fit to Sigs, Glocks, and real informative 1911s.

Here is an updated table adding other models—please review and comment, thanks.

So am I to understand that with the P226, a .40 version and a 9mm version are the exact same except for the barrel, recoil spring and mags? Locking block too? I.e., the .40 P226 doesn't have a different mass slide than a 9mm?

dwg13013 · Dec 28, 2013

The 220 will do 400 Corbon with a Fire dragon barrel. Bar-sto quit making one. Luckily I found a Bar-sto and man is it fun. Especially with an SRT.

Sig Sauer P220 400 Corbon Conv. Interchangeable with 45 ACP

Newbie62 · Dec 28, 2013

Don't forget about the 22lr slide conversions!

pduque · Dec 28, 2013

I have that listed on the 9mm P226, does it belong elsewhere as well?

Malicious Compliance · Dec 29, 2013

For the P229 and P226, starting with a 9mm slide, the 357 and 40 X-change would be appropriate responses in place of N/A. Also, for both these models, starting in 40 or 357, a 9mm conversion barrel would be required. Different than the P239, where the standard 9mm barrel will fit.

pduque · Dec 29, 2013

Here is another update. Make sure I have all nomenclature, spelling, etc. correct.

Also, if you want a PDF in Reader to add your comments send me a PM.

Thanks much.

jtallen83 · Dec 29, 2013

This would make a good sticky! Thanks for posting the info:salute2:

dwg13013 · Dec 29, 2013

I would 2nd that.
When I first wanted to try multi I searched all forums looking for info.

bearone2 · Dec 29, 2013

caveat emptor on drop-in barrels:

from tgs:
These are factory Sig Sauer drop-in barrels.
* NOTE * All barrels may required minor fitting.

Malicious Compliance · Dec 29, 2013

One last suggestion: the 22lr conversion kits will work on the P229 and P226 - 9mm, 40 S&W and 357 SIG frames.

ThnkFrst · Dec 29, 2013

I thought from Bricktop's input that the P239 would take a Sig factory .40S&W, .357Sig and 9mm barrels in the same slide. Is that correct?

pduque · Dec 29, 2013

Good question, I don't know for sure.

pduque · Dec 29, 2013

Next draft. Good suggestions gentlemen. Can anyone verify the P224 data?

pduque · Dec 29, 2013

I changed the column heads from slide to frame, which is more accurate?

dwg13013 · Dec 29, 2013

Now your really getting complicated.
The 229/228 frame could not go up. The 229-1 frame is a 40 frame so can do it all. :lol:
I think staying with slide is good.
Also your chart had the 239 correct before Thinkfirst's question.
the 239 can use standard barrels for all three.
It is a great chart.

Toupolo · Dec 29, 2013

I have a 229 in .357sig. I also have a compensated .40 barrel. With the .40 barrel, I'm shooting low. Would I have to change the sights also if I want to swap over? I understand the differences in flight pattern between both rounds. Just trying to find the cheapest and most reliable solution. Any suggestions?

pduque · Dec 29, 2013

Thanks to all for your comments, I think we are getting close to nailing this down and then we can add other pistols. Based on some of your comments I have tried to make it read a little more user-friendly.

I have added footnotes so let me know if there should be any other item denoted with a footnote.

Sig 9mm · Dec 29, 2013

Wow. Nice work. Great chart.

This would make a great "sticky". Something I would definitely use as a reference for future P series purchases.

I would add what you need and don’t need. As an example:
You have a P239 40 S&W and want to convert it to 9mm.

You would need (1) 9mm magazine (2) Recoil Spring (3) whatever.

Give them enough information so they can at least have a 80% solution.

dwg13013 · Dec 30, 2013

I have a 239-40/357/9mm and all I needed was barrels. Most newer springs will do it all. Worn ones may not.
The mags. do all three calibers 100%

jlamb · Jan 4, 2014

Hi guys. New to the forum. I'm in the process of getting a 239 in 40s&w. Now if I understand you correctly all I have to change is the barrel to shoot 357 sig and 9mm. No other changes need to be made such as magazines?

Barrel/Caliber Conversions

What about the 2022 & 2340 series?

jibarnes · Jan 11, 2014

I know the 2340 barrel also comes in 357, I have one.

mtnboy · Jan 15, 2014

Hello and great job,

P220 also has a .22 conversion kit.

It would also be nice to know what is the source of the conversion. For example the caliber exchange kits are Sig, what about the conversion barrels? Barstow?

thanks

pduque · Jan 15, 2014

I will look to add that data over the weekend. Thanks for the heads up.

Very cool chat easy to read looks good so far, I'm in the market for a p239 40 cal / 9mm. With this info I should be able to get the 40 and add a 9mm drop in and Mag? If I'm reading it right.

Malicious Compliance · Jan 30, 2014

You are reading it correctly! The 9mm SIG factory barrel will drop right in.

skilla · Jan 30, 2014

I have a 226 originally chambered in 40 cal. I bought stock sig replacement barrels from Top Gun Supply in 9mm and 357sig and the barrels all work fine in the gun. 9mm doesn't feed reliably in the sig 40/357 mags but my 40 cal mecgar mags will. It may have to do with the mag followers.

I also own a 2022 in 40 and did the same thing. The 9mm 2022 stock replacement barrel fits that gun perfectly however the sig 40 cal mags wont feed 9mm reliably. Any more than 10 9mm rounds and the rounds will bind in the mag.

I would not recommend using the SIG 9mm barrel in a 40/357 slide of either a P226 or P229. The barrel OD of the 9mm is smaller and won't ride properly through the opening in the end of the slide. The aftermarket conversion barrels are fabricated with larger OD's to address this concern. On the P239, however, the OD size is the same on all three SIG factory barrels, 9mm, 40 S&W and 357 SIG, hence the recommendations in the chart as developed.
