9mm – +P+ 90 Grain Xtreme Defender – Underwood – 20 Rounds For Sale

This 9mm +P+ cartridge by Underwood features the Xtreme Defender projectile by Lehigh Defense. It’s a rather unique self-defense projectile, as it does not expand as it penetrates its target. The 90 grain solid copper bullet is instead shaped like a drill bit, and its radial flutes cause cavitation which may be up to double the diameter that a hollow point could have yielded. What’s more, the Xtreme Defender’s profile permits it to much more easily break through tenacious urban barriers, penetrate to a depth of up to 16 inches, and furthermore promotes more certain feeding in a semi-automatic firearm.

An Underwood cartridge is designed to truly deliver under any circumstances. That’s why every one of their rounds is loaded with flash suppressed propellant, so that your ability to line up accurate follow-up shots won’t be impacted should you have to stand your ground in the dark. This round also features a nickel plated brass casing for enhanced resistance to corrosion as well as smoother feeding and extraction. It has been plated via the Ducta-Bright 7a process, which fares better when exposed to the greater heat that a +P+ load can create.

Please do note that this is +P+ ammo and ought to have nothing to do with any weapon that isn’t rated for it. Also, note that in an effort to increase production efficiency, the round may not have a “+P” headstamp traditionally found on pressure rounds.
