If you're not meeting minimums for reloading of a given cartridge it's adviseable not to go through with it. The lightest bullet I'm aware of for 9 X 19 is 115 grains. It has a different contour than either 9 X 17 (.380) or 9 X 18 (Mak) and may cause feeding and ballistics problems in your pistol.
Maybe nothing bad will happen, but may be better to go with what's designed for use with 9 X 19 than to push the envelope with that combination.
