Howdy Mr. Arcman,
I have a 9mm down/converstion barrel that I use in my stainless steel P226R purchased in 357 Sig, that functions flawlessly. I simply use a 17 rd Mec-Gar 226 9mm mag for all 3 calibers (357, 40, and 9mm). The 9mm down/conversion barrel is different for a stock 229 barrel, as it is made specifically to hae the same outer diameter as the 40/357 Sig barrels, so it will fit properly in your slide.
The barrel I have was purchaed from EFK Fire Dragon, and was a straight drop in with no fitting required. I have this barrel and his 357 Sig conversion barrel for my FN HP 40, and both are true drop ins. They were both a bit cheaper as well, somewhere around $150.00. I own one Bar-Sto barrel that I obtained for 357 Sig to convert my CZ75-B 40 to that caliber. While I orderd the semi-drop in, my CZ gunsmith has stated that it is going to require some extensive fitting as it in not a drop in. So just a suggestion sir, you might want to take a look at the EFK 229 9mm down/conversion barrel as well. I feel both of my EFK barrels are far more accurate than I can be too.
The only thing I have noticed is that if I were going to shoot a ton of 9mm rounds, I would probably want to swap out the recoil spring to one designed for 9mm rather than using the same spring installed in my pistol for the 357 Sig / 40 rounds.
Hope this helps a little sir.
