The P226 40 S&W runs just fine with an OEM SIG 9mm barrel.A good friend of mine wants to sell his P226 in .40
I have NO desire for a .40
None
Rolled the idea around of picking up a Bar-Sto 9mm barrel for it, but the thought of having to fit that barrel, makes me think twice
Unfortunately that doesn't work for a 229. And while a factory 9 barrel will fit and function in a 40 226 the rear locking lug on the 9 barrel is just a bit narrower than the 40 so you won't get as good of lockup.The P226 40 S&W runs just fine with an OEM SIG 9mm barrel.

While you are correct on the width of the hood extension of the 9mm barrel being a bit more narrow than that on the 40/357 barrel (~1.0mm), I find the lock up to be just fine. In fact, I use a Silencerco 9mm threaded barrel in my 40 S&W native P226 with my AAC EVO 9 mounted and the lock up is still quite nice. I would think, with all the forces imparted on the barrel with the suppressor up front, lock up would be tested quite vigorously. My Silencerco barrel, which is dimensionally the same as a SIG OEM P226 9mm barrel, performs very well.Unfortunately that doesn't work for a 229.

I had none of the above when I fitted some (lesser) barrels for my SIGs.
No tools, no knowledge, and toes for fingers.
I eventually got some nice toolz, all the way up to some Gesswein Ruby Rods (not really necessary, but awesome candy) by the time I did some barrels for my Glocks.
After spending all that dough on toys, I eventually settled on using 600 and 1200 grit sandpaper wrapped around a straight rod with a square cross - section (almost exclusively), with a lot of painter's tape.
And I have since grown opposable thumbs as well.
Fit your barrels and post away recklessly, my friend.
