Underwood Ammo XTP Features The Underwood Ammo XTP combines Hornady s eXtreme Terminal Performance bullet technology with Underwood s own load development to produce a lethal accurate .380 ACP round. The 90 grain jacketed hollow point is engineered for deep penetration and reliable controlled expansion giving it dependable performance against common defensive threats. At 1025 fps and 210 ft lbs of muzzle energy the subsonic profile of this load keeps recoil manageable in smaller framed .380 pistols. Underwood also loads this ammunition with flash suppressed powder preserving the shooter s vision if the firearm must be used in low light. Nickel plated brass casings improve feeding across a variety of pistol actions while resisting corrosion far better than traditional brass. The plating keeps cases looking clean in storage and simplifies cleanup for anyone who reloads spent brass. These cases will not tarnish even after contact with leather moisture or other metals an important detail for ammunition carried daily in a holster or magazine. Boxed 20 rounds at a time the Underwood Ammo XTP is built for shooters who demand consistent field tested performance from a compact defensive cartridge.
