Product Description

UNDERWOOD

9mm +P — 68 Grain EXTREME DEFENDER Solid Monolithic — 200-Round Box

UPC: 816874022815 · Pack: 200 rounds/box

Description

9mm Luger +P defensive cartridge loaded with a 68-grain Extreme Defender solid monolithic projectile. Single-piece, high-integrity projectile engineered for deep penetration and high retained mass. Brass-cased, boxer-primed, and packed 200 rounds per box. Intended for defensive and tactical applications where barrier performance and reliable feeding are priorities.

Usage

Primary: self-defense, law-enforcement, and tactical scenarios that require enhanced penetration and retained mass. Secondary: specialty applications favoring monolithic solids for barrier defeat. Not recommended where controlled expansion and maximum soft-tissue energy transfer are the priority.

Performance notes

  • Penetration: Deep penetration and high retained weight; effective barrier performance (auto glass, doors, light cover).
  • Terminal behavior: Minimal expansion vs. hollow points — generally narrow, deep wound channels and greater over-penetration risk.
  • Accuracy: Light, high-velocity 68gr projectiles produce a flat trajectory; groups vary by firearm and barrel length.
  • Recoil & wear: +P increases chamber pressure — snappier recoil and more muzzle blast; repeated +P use can increase firearm wear if not rated for +P.
  • Feeding & reliability: Solid monolithics are robust and typically feed reliably; test in your firearm before duty/carry.
  • Reloading: Brass boxer-primed cases are commonly reloadable; inspect primer pockets and case integrity before reloading.

Summary

UNDERWOOD 9MM+P 68GR EXTREME DEFENDER (200-round box, UPC 816874022815) is a +P defensive load built around a 68-grain solid monolithic projectile. Estimated muzzle velocities are approximately 1,700–1,900 ft/s, producing roughly 437–545 ft·lb of muzzle energy. The design prioritizes penetration, retained mass, and feed reliability, at the cost of reduced expansion and increased recoil and firearm stress. Confirm +P compatibility for your firearm, function-test the load, and follow all applicable safety and legal requirements.
