If your P229 is in .357 Sig, then a Bar Sto conversion Barrel in 9mm would be fine, as well as a Recoil Spring. Should be able to use the .357 Sig sight without problem. The fitting of the barrel, will have some influence on that as well.

Your knowledge is simply outstanding!!!With P229s, the .357 Sig/.40 S&W Barrels have larger outside diameter tubes, than the 9mm factory barrels, so the factory barrels cannot lockup as securely in the slide. This is in addition to the hood extension width. The OEM Barrels are sized to fit their respective breech cuts, where the 9mm is 0.030" narrower than the .357/.40 cut, so the "Conversion" 9mm Barrel will have the wider .357/.40 hood extension width. allowing tighter barrel lockup.
With P226s all barrel outside diameters are the same, regardless of caliber, so reasonable lockup is maintained even if there is a narrower hood extension.
Yep, figured that goes without saying, they’re the easy part of the equation. Making up my damm mind about which one to start with is another story. 😎...also you'll need 9mm magazines...
Enabler!Take a look at the SP2022.
I took these some time ago. Maybe they can be helpful…I just received a complete full size 9mm slide with a Romeo 1 red dot for my P320. I don’t have a scale to truly compare the two but the 9 seems to weigh a lot less, has anyone else noticed this? I’m tempted to buy a scale to satisfy my curiosity but if someone else already knows for sure it’d help put my mind at ease.
