380 Automatic Colt Pistol Ammunition

380 ACP (automatic colt pistol) is a straight-walled pistol cartridge without a rim that has a rich history dating back to the early 1900’s. The round is also commonly referred to as the 9mm Corto, 380 Auto or 9x17mm.

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 marked “+P”, meaning they are loaded to a higher pressure than the average round. While many shooters find that higher pressure desireable 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 loaded 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.
