What do I need to convert P226 from .357 Sig to 9mm? Login/Join

Recently acquired a P226 in .357 Sig. I would like to know/confirm what all is needed to convert my pistol to shoot 9mm. Obviously, I would need a 9mm barrel,( but which one?). Reading on the interweb, some people have advised a Barsto 9mm conversion barrel is needed. I have also read, just a regular 9mm barrel ( Sig or other replacement) can be used.

I know, i would have to get 9mm mags and a recommended 9mm recoil spring? does that sound about right?

Anyone that has done this, I would appreciate their input and suggestions. Thank you .

A standard 9mm factory barrel might work, but it will be a looser fit in the slide and therefore might not work. A conversion barrel is intended for the purpose. Usually 9mm magazines are likewise recommended; 9mm ammunition may not work properly in a 357/40 magazine. The standard 357/40 recoil spring may cause cycling problems, but maybe not, especially if hotter 9mm ammunition is used. Nothing else should be necessary although the 357/40 ejector is somewhat different than the 9mm version.

Why not look for a Sig 226 9MM conversion kit they sell for their .22-226's?

It includes a whole new slide/top end/barrel & Mag?

I have the kits for my P-226 .22 Classic in 9MM &.357 Sig and it extends the usefullness of the 226 greatly, imho.

In .22, it's a great trainer, but still suffers from typical .22 reliability issues.

With the caliber x-change kits, it becomes a very reliable and potent centerfire defense gun.
As it is designed to be.

I have my name on the wait list at Sig and Osage county guns for the conversion kit. I hate waiting.

Thanks DC3S,,,,, i looked at those... I just hate having to wait for those to be made,,,just like the Bar Sto barrels. Just Saw on the Sig site that they have a conversion kit in stock for $407.

Just trying to think of cost effective way to accomplishment what I want.

For $407, I'd spend a little more and buy another 226 used, that's already in 9mm. The additional gun will always be worth about what you paid for it. A conversion barrel and parts accompanied by the .357 gun in a sale won't bring nearly as much return on investment if you go to sell the package.

I've heard of a lot of people buying used standard 9mm barrels and using them, just not sure what accuracy they're achieving. I would think the tolerances should be fairly close as it is a production gun. I've also heard the Barsto's and EFK's do need minor fitting most of the time.

I have a P226 Legion SA/DA 40 S&W caliber, I bought an complete upper came off from an P226 Legion SA only 9mm here, I went to the range in Friday test fire. It works like a normal P226 9mm when I swap the SA upper 9mm on to my Legion 40 S&W caliber. Now I got two calibers in one gun Smile

I have a P229 legion 357 SIG that I bought a 40 barrel for and everything works perfect including mags. SIG had a great sale a couple of weeks ago and 9 mm conversion kit for 229 and 226 with Romeo 1 reflex sight installed on slide. Came with 9mm barrel, spring, slide and Romeo1 for 475. Shoots sweet and 25 yds. Now I have a three in 1
