TiteGroup and Clays are both very spikey and not what I would want to use for 9x19 unless I had nothing else. Load low and don't try for anything near max. Try to keep the COL as long as possible. 9x19 is very sensitive to changes in COL and bullet set-back.
If I wanted a fast powder for 9x19, I would use 231/HP38, AA2, and N320.
If I wanted a defense load duplicate, I would use Silhouette or HS6 powder.
Follow your manuals' guidelines and keep COL longer than the manuals reference.
