This is very powerful 9mm ammunition by Underwood of Illinois. Sure, its bullet is light at 90 grains, but its 1,550 fps muzzle velocity is phenomenally fast. That’s why it has the +P+ designation. That’s also why you must make absolutely certain your firearm is designed to handle its unusually high chamber pressure. Do not order this ammo if your pistol or carbine isn’t rated for +P+.

This round’s potency isn’t the only reason why it’s such a definitive solution to personal protection. It is loaded with the Xtreme Defender by Lehigh Defense: a rugged solid copper projectile that achieves reliably deep penetration, even if it has to pierce a barrier before reaching its target. The Xtreme Defender cannot expand. Instead it uses specially designed flutes to generate immense hydraulic pressure, effectively blowing soft tissues outward so as to establish a cavernous permanent wound column.

Underwood loads this ammo’s monolithic bullets in nickel-plated brass cases: smooth cycling, corrosion resistant, and reflective to facilitate low-light chamber checks. Each bullet is backed by a reliable Boxer primer, as well as low-flash propellant that will help you maintain visual on the target upon firing your initial shot.
