I am wanting to Buy a P226, but I can' decide between 9MM or .40 S&W I want both but I can't afford two (2) Pistols now. So I was wondering if I could change a 9MM to a .40S&W by changing Barrels recoil springs & magazine?

I am betting someone here knows the answer.

Yes.

SIG actually makes kits for this.

I would recommend calling Sig with this question before you buy.







From what I read, the xchange kits only apply if you are starting with the 22 Classic pistols as a base frame



Historically with the classic series if you start with a 9mm it will forever be a 9mm, no changes in caliber.

If one starts with a 40S&W you can get a drop in barrel to switch to 357Sig or can purchase a conversion barrel to be able to shoot 9mm. Conversion barrels are not available from Sig but can be had from companies such as BarSto. I do not believe that the xchange kits would apply to a 226 originally set up as a 9mm.







To be safe, I would start with the 40S&W and get a BarSto conversion barrel if you want 9mm. I have read of some frame rail wear and damage as a result of switching between .22 and centerfire slides. I have no personal experience to back this up just wanted to mention that I have read mixed reviews with switching between rim and centerfire.





I have been using a BarSto 9mm conversion barrel in my 226 Equinox for a number of years with no issues at all. Although it is said that you can use the 40 mags for 9mm, my experience has not agreed. I purchased 9mm 226 mags for use with the BarSto bbl.

Buy the 40. You can get a SIG barrel to go to 357SIG and Barsto makes a 9mm barrel.



I have read about four different stories and the X-Change kits... A couple yes and a couple no!...

But in the 40 it's just the barrel and magazines for the 9mm and just the barrel for the 357/40 (Same mags).

I'd do what Lateck said.



I bought a Sig P229 in .40 cal



Bought a Bar-Sto 9mm barrel and it works great.



Bought a .22 kit & it works great.



So it's 3 guns in one

Here's an up-date for any one how might care:

Over the weekend I got a New Simi-custom Bar-Sto 9mm barrel and had my local gunsmith fit it to my P226 (.40S&W) and today I ran 50 flawless rounds through it







So, now I do have a 3 caliber SIG P226 (I'll make it 4 later this year with the .22 kit) .40S&W, 357SIG & 9mm.... So this way you CAN have a Multi-Caliber 226







Lateck,

If you buy a Sig P226 in .40 cal - it can be converted to a 9mm using a Bar-Sto 9mm barrel.



I've done it to my Sig P226 X5











And on my Sig P229











Great guns both of them.



Very slight "fitting" needed on the P229 barrel.



I never shoot .40 cal through them any more.

The answer to the original question is nope.



You can go down in caliber from the original frame/slide, not up. So .40 to .357, for example. All you need do is drop in the .357 barrel. The same .40 magazine even handles both cartridges. I know about these, dunno about .40 to 9mm.



I would think that if a 9mm set up could be made to work on a .40 frame, that both a new slide/barrel combination and magazine would be required.

No, because the 9mm breech face is cut for a 9mm cartridge.

To best answer/ clarify/ verify all THREE comments, I would ask "littlebob" from this Thread:

He seems to have everything figured out lol

HeyDondavis,







I amalso Very interested in an X5 Allround. I was deciding between 9mm or .40, butit would appear that you have found the answers I was looking for. The onlyquestion i have is the fact that the X5s obviously comes with a slightly longerbarrel than the regular 226--- Am i safe to assume that not ONLY was theconverted barrel 5', but the Slide is completely separate (tailored for 9mm) aswell? Hence giving you 2 different slide setup with 2 differentCalibers....sorry if im not making any sense lol

When 226 lowers are made, there is no caliber recognition or designation to the frame. The frames are identical - whether it ends up as a .40/.357 or 9mm. Much of what has been posted above is accurate. You can buy a .40 and drop a .357 barrel into the slide, and visa-versa, and you're good to go. The outside diameters of the two barrels are the same and therefore will work in your particular .40/.357 slide.



The outside diameter of the 9mm barrel, however, is smaller than that of a .40/.357 barrel and therefore the barrel opening on the slide is smaller. That is why you cannot drop a larger .40/.357 barrel into a slide designated for a smaller outside diameter 9mm. Bar-Sto makes 9mm barrels that are over-sized and made with the same outside diameter of the .40/.357, that is why they can be dropped in into a .40/.357 slide. So, if wanting to change only the barrel to have various calibers, buy a .40 or .357 and get a drop-in 9mm barrel.



While this sounds to be the optimum solution, it can have drawbacks. You have to first have a .40/.357 and then purchase a 9mm barrel from Bar-Sto. Then, it's possible that when using a drop-in barrel, the POA/POI will not be in agreement with that the original barrel. There is not a solution to this. Sight will be left/adjusted for one or the other and Kentucky windage will have to suffice for the remaining barrel in your slide. And while using a drop-in barrel MIGHT not cause sighting problems - it could. This was confirmed when speaking to Bar-Sto about using their conversion/drop-in barrels.



The other is to purchase a conversion kit from Sig. This kit contains a slide, barrel, recoil guide rod and spring, for the caliber you want and allows you to purchase whatever caliber you want initially and then convert it with the slide/barrel combination. It also allows you to adjust your sights on each /slide barrel combination for correct POA/POI so that changing calibers will not have an effect in your sight set-up.



Hope this helps.

Thank you Sig Marine!

Hello all! I am new to this forum. A 1911 and, obviously, a 45ACP person (since my mil service). Recently got a Sig 1911 XO (excellent experience so far). Currently looking to the p226 platform, in particularly intrigued by the option to switch between 9 mm and 40SW. I have been looking around the internet for a while on this issue and Sig-Marine's answer has been the most comprehensive one. My feeling (i.e. no armorer's experience but as an enginner) is that the "correct" way to convert 9 mm to 40 and visa versa is to go for the Sig conversion kits; i.e. slide+barrel+spring.
Again, hello to all, and special thanks to Sig Armorer!
