The heaviest bullet in my reloading manuals for the .380 is a 120 grain cast bullet.
It depends on the bullet weights. The 9 mm (AKA 9x19 mm, 9 mm Luger, or 9 mm Parabellum) is faster than the .380 ACP (AKA 9 mm Kurz) except when you compare the lightest .380 bullets to the heaviest 9 mm bullets. If you compare the same bullet weights in each, the 9 mm is always faster.
the most common weights are 90 and 95 grains, but they are available in other grains. I think 105 is the heaviest available.
