Sounds like you are making progress. That is good. 9MM makes a difference. I use a BarSto conversion barrel. If you ever want to try 357SIG or a 226, let me know. It can be arranged with a trip to Cape Cod The difference between a 229 and a 226 is huge and I actually prefer the 226.
Keep practicing and if you need 9MM mags, the 226 mags using an X grip adapter work great
I too have a Bar Sto 9mm barrel for my .40 P229. I've never had a malfunction using it, and with .40 mags and recoil spring. I love it.
