$26.06
The Underwood Ammo .380 ACP +P 68gr Xtreme Defender is a modern, lead-free self-defense round engineered for reliable stopping power in compact and subcompact pistols. Built on nickel-plated brass cases with boxer primers, this ammunition delivers 1400 feet per second muzzle velocity and 296 foot-pounds of energy—enough to get the job done when it counts. The copper-constructed projectile is designed with proven self-defense geometry, making it a smart choice for anyone serious about personal protection in a .380 platform.
What sets the Xtreme Defender apart is its attention to terminal ballistics. The 68-grain bullet carries a solid sectional density that promotes consistent penetration, while its G1 ballistic coefficient of 0.087 keeps the projectile stable in flight. The round travels supersonic, delivering reliable performance downrange. Best of all, this ammunition is rated safe for use in suppressors—a real advantage if your .380 pistol is equipped with a can or you're planning to add one.
Underwood's commitment to non-corrosive, reloadable brass means you're not locked into single-use ammunition. Once you've fired these rounds, the cases are yours to reload, making this a practical option for shooters who handload. Each box contains 20 rounds, so you get a solid practice or carry amount in a single purchase. Whether you're stocking up for range work, serious carry ammunition, or building a defensive supply, the Xtreme Defender delivers performance without the lead-contamination worry.
