The Underwood 380 ACP +P 100gr Flat Nose ammunition is purpose-built for defensive and tactical applications where reliable stopping performance is non-negotiable. Designed for law enforcement, armed security, and civilian self-defense, this cartridge combines modern ballistic engineering with proven flat-nose bullet geometry to deliver consistent terminal performance. Each box contains 20 rounds, with cases of 10 boxes available for agencies and high-volume users who demand consistent quality across large quantities.
The 100-grain flat-nose projectile is the critical element that distinguishes this load from standard 380 ACP offerings. Flat-nose bullets expand more reliably upon impact than round-nose designs, creating a larger wound cavity and reducing over-penetration risk—a vital consideration in tactical and civilian environments where threat mitigation must be precise. The +P pressure specification delivers elevated velocity compared to standard 380 ACP loads, increasing kinetic energy delivery without sacrificing firearm longevity in weapons rated for +P ammunition. Underwood's quality control ensures consistent powder charges, primer seating, and bullet construction across every round, a requirement for duty use where reliability failures are unacceptable.
This ammunition is ideal for shooters who rely on compact 380 ACP platforms—including Ruger LCP, Kel-Tec, SIG Sauer P238, and similar subcompact pistols—where ballistic performance cannot be compromised despite design constraints. Law enforcement agencies and security teams using 380 ACP as a backup or off-duty round will appreciate the terminal ballistics advantages of the flat-nose design. Before use, verify that your specific firearm is rated for +P ammunition; while most modern 380 pistols handle this pressure safely, older or specialized firearms may require standard-pressure loads. The 20-round box format allows for practical range testing before duty deployment, while bulk case quantities serve armories and training facilities with ongoing ammunition needs.
