Underwood Ammo Xtreme Defense Platinum Features The Underwood Ammo Xtreme Defense Platinum load pairs an optimized nose flute with total weight and velocity tuned to reach penetration depths up to 18 inches. The solid copper monolithic body will not separate on contact with barriers so the permanent wound channel stays consistent whether the round passes through soft tissue or automotive glass first. This 9mm load reaches 1700 fps with the 68 grain bullet generating 436 ft lbs of muzzle energy for decisive stopping power. Because the design achieves expansion despite barrier interference shooters can trust this round in real world defensive scenarios where a clean shot is not guaranteed. Nickel plated brass casings improve feeding across pistol actions while resisting corrosion better than traditional brass during storage. The plating also eases cleanup during reloading and resists tarnishing from contact with leather moisture and other metals in a holster or range bag. Each 20-round box is supersonic rated giving concealed carriers and duty shooters a dependable defensive load. This combination of penetration reliability and corrosion resistance makes the Xtreme Defense Platinum a strong option for everyday carry 9mm pistols.
