It's not too unusual for different weight bullets to have different points of impact but, what you are describing sounds like a shooter problem. You may have developed a flinch or some other problem. Put the .22 away and concentrate on the 9mm. Go for quality practice not quantity. 25 rounds fired carefully and with concentration will beat 100 rounds fired sloppily. Dry fire is what you do in quantity live fire to verify you are doing it right.
Down load and print this target

It's not all that unusual for a shooter, especially a new shooter, to hit a plateau and need to do some serious reprogramming. Sometimes a few weeks off is all the medicine you need.
Good luck!
