General Ballistics and Specs of 380 ACP Ammo:

Generally, you’ll find .380 ACP rounds in weights ranging from 90 grain up into the 102 grain range. Although you may find a rare cartridge slightly lighter or more heavy. Additionally, it’s not uncommon to find commercially loaded rounds mark “+P”, meaning they load to a higher pressure than the average round. While many shooters find that higher pressure desirable in a self-defense round. You should consult your manufacturer or the owner’s manual of your firearm before determining if you want to use ammunition load to higher pressure. Generally, manufacturers do not advise you shoot +P ammo because it can cause more wear and tear on your barrel than standard-pressure rounds.
