When I was shooting lead (124s) ( 9mm Luger) I really liked Universal
For the lighter 102s if I was buying powder I would choose AA#2.
However, I would be tempted to load them with whatever I had on hand that I could find data for. (115 lead data might be a good start if you can't find data for 102s....MAX charge with the 102 should be a little higher but that data should get you in the ballpark)
Sometimes you can just never guess what you gun might like best, I am thinking a powder on the fast side of the 9mm range but it could be happier with something on the slower side like CFE-P,
no way to know for sure until you try.
