Availability: In Stock
Underwood Ammo 9mm+P 147-grain hard cast flat nose ammunition delivers a serious self-defense and training round built on proven brass cases you can reload. Loaded to +P pressure levels, this full-power cartridge pairs heavy 147-grain hard cast projectiles with a flat nose design—a combination favored for controlled expansion and penetration where it counts. At 1100 feet per second, the round develops 395 foot-pounds of muzzle energy and maintains supersonic velocity downrange, making it a capable choice for defensive pistols, competition, and serious practice.
Underwood backs this ammunition with quality manufacturing standards: new production, non-corrosive boxer-primed brass cases that reload cleanly, nickel-plated for smooth feeding and corrosion resistance. The hard cast construction and flat nose geometry are engineered to perform reliably in modern defensive and tactical platforms. If you run a suppressor, this round is safe to use with one, giving you flexibility in your setup.
Whether you're building a duty load, training hard at the range, or stocking reliable defensive ammunition, Underwood's 9mm+P 147-grain rounds offer the velocity and ballistic performance serious shooters expect. Each box contains 20 rounds; the 10-case quantity means you get 200 rounds total—enough to work up loads, run extended practice sessions, or keep your preferred round in stock.
