The Underwood Ammo 9mm 90gr Xtreme Defense delivers exceptional terminal performance through its solid copper construction and unique fluted design. This premium defensive ammunition combines maximum penetration with controlled expansion for reliable stopping power.
What Makes This Different
Unlike traditional hollow point designs, the Xtreme Defense projectile features precision-machined flutes that create permanent wound channels while maintaining structural integrity.
