Availability: In Stock
The Underwood Ammo .380 ACP +P 90-grain XJH round is a compact-carry defensive load built for self-defense in .380 ACP pistols rated for +P pressures. Underwood loads these rounds with a 90-grain brass bullet at 1200 feet per second, delivering 288 foot-pounds of muzzle energy—a proven combination for stopping power in a caliber that prioritizes shootability and concealability. The XJH bullet design is engineered to perform reliably in defensive scenarios where shot placement and consistency matter most.
Built on nickel-plated brass cases, these rounds are new production, non-corrosive, and fully reloadable, so you can reload once you've fired through them. Underwood's ammunition is loaded to tight tolerances and tested for reliability across a range of .380 platforms. If you run a suppressed .380 for home defense or range work, this load is rated safe for use with suppressors—a practical consideration for modern .380 shooters.
Each box contains 20 loaded rounds, making it easy to stock up for carry, training, or practice. The 90-grain weight and 0.099 G1 ballistic coefficient keep the bullet supersonic (traveling faster than the speed of sound), reducing trajectory drop and maintaining velocity over typical defensive distances. Whether you're carrying a Ruger LCP, Sig P238, or Kel-Tec for backup or primary protection, Underwood's .380 +P load is a no-nonsense choice that respects the limitations of the cartridge while maximizing its potential.

Yes. Underwood designed this load to be suppressor-safe, so if you're running a suppressed .380 pistol for home defense or range shooting, this round will function reliably with a can attached.
Yes. These are new production, non-corrosive boxer-primed cases on nickel-plated brass, which means they're fully reloadable once you've fired them. Just account for the +P pressure when working up loads.
This is loaded to .380 ACP +P specifications, so it's designed for firearms rated for +P pressures. Always check your pistol's manual or markings to confirm it's rated for +P ammunition before use. Do not use in firearms marked for standard .380 ACP only.
This round is primarily engineered for self-defense applications. While the supplier notes it can be used for hunting, the .380 ACP cartridge and 90-grain bullet are better suited to defensive use. Consult local hunting regulations and game-appropriate loads if you're considering it for that purpose.
