Underwood Ammo
Underwood Ammo 138 9mm Luger +P ammunition delivers serious stopping power for shooters who demand reliable self-defense rounds. These 147-grain jacketed hollow point cartridges are loaded to +P spec in nickel-plated brass cases, offering the combination of velocity, energy, and expansion needed for defensive carry in modern 9mm pistols. Whether you're running a duty gun, EDC, or competition rig that can handle +P pressures, this load brings proven performance and consistent reliability to the range or carry rotation.
The 147-grain bullet weight sits at the heavier end of the 9mm spectrum—a proven approach for controlled expansion and penetration. Loaded to 1175 feet per second, these rounds produce 451 ft-lbs of muzzle energy and maintain supersonic velocity downrange, making them an effective choice for both defensive and hunting applications. The nickel-plated brass adds durability and corrosion resistance, and the boxer primers mean you can reload once fired if you're into handloading.
New production ammunition from Underwood arrives non-corrosive and ready to shoot. The jacketed hollow point design is suppressor-safe, so if you run cans on your 9mm platforms, this ammo cycles cleanly and reliably. Each box contains 20 rounds, and bulk ordering by the case (10 boxes) makes resupply straightforward for folks who shoot regularly.
As with all ammunition, verify that your specific firearm is rated for +P loads before use—not all 9mm guns are designed for the higher pressures these cartridges produce. Read all ammunition and firearm documentation carefully.
