Product DescriptionLehigh Defense Xtreme Penetrator ammunition in 9mm Luger is built around the company's Fluid Transfer Monolithic (FTM) projectile design for reliable, straight-line penetration and a large permanent wound cavity without relying on bullet expansion. The progressive nose geometry and radial flutes are engineered to displace hydraulic energy in tissue, helping maintain consistent terminal performance even after passing through common barriers such as heavy clothing or drywall. This load features a solid copper, lead-free projectile paired with a brass case and centerfire primer, packaged 20 rounds per box (10 boxes per case), making it a strong choice for defensive use and function testing in compatible 9mm Luger firearms.Product Highlights Xtreme Penetrator (XP) Fluid Transfer Monolithic (FTM) design for deep, straight penetration and strong fluid displacement Solid copper, lead-free monolithic projectile for barrier-capable performance and reduced lead exposure Progressive nose geometry with radial flutes to create a large permanent wound cavity without traditional expansion Brass-cased, centerfire 9mm Luger handgun ammunition for reliable feeding and extraction Convenient packaging: 20 rounds per box and 10 boxes per caseSpecs Brand: Lehigh Defense Manufacturer Part Number: LA9115XP UPC: 810025508616 Caliber: 9mm Luger Bullet Weight: 115 grain Bullet Type: Xtreme Penetrator (XP) / Fluid Transfer Monolithic (FTM) Case Material: Brass Primer Style: Centerfire Lead Free: Yes Muzzle Velocity: 1100 ft/s Muzzle Energy: 309 ft-lbs Rounds Per Box: 20 Boxes Per Case: 10Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
