$20.12
Underwood Ammo 9mm+P+ ammunition delivers serious stopping power for shooters who demand reliability in a self-defense round. This 124-grain jacketed hollow point load pairs velocity with controlled expansion, making it a proven choice for personal protection and duty applications. Loaded to +P+ pressure specs in nickel-plated brass cases, these rounds are non-corrosive and reloadable—giving you flexibility whether you're stocking up for range training or carry use.
At 1300 feet per second, this 9mm+P+ round travels supersonic and generates 465 foot-pounds of muzzle energy. The 124-grain bullet weight balances penetration and expansion for consistent performance downrange. With a ballistic coefficient of 0.118, you get respectable flight stability, and the jacketed hollow point design is engineered to expand reliably on impact. Lead is present in the bullet; shooters concerned about lead exposure should take appropriate precautions during handling.
Each box contains 20 rounds of new production ammo, with 10 boxes per case for convenient bulk purchasing. The nickel-plated brass construction resists corrosion and feeds smoothly through most 9mm firearms. If you run a suppressed pistol, this load is rated safe for use with sound suppressors, so you can train or carry suppressed without concerns. Underwood's reputation for consistent quality and hard-hitting performance makes this a trusted option for shooters who take their defensive ammunition seriously.

Frequently Asked Questions
Will this 9mm+P+ ammo work in my standard 9mm Luger pistol?
This ammunition is loaded to +P+ specifications, which means it operates at higher pressures than standard 9mm Luger rounds. You must verify that your specific firearm is rated for +P+ ammunition before use. Check your owner's manual or contact the manufacturer if you're uncertain. Using over-spec ammo in an unsuitable gun can damage the firearm or create a safety hazard.
Can I reload this brass?
Yes. The cases are new production, boxer-primed, non-corrosive brass that's fully reloadable. After firing, you can resize and reload them like any standard brass—a great way to reduce ammunition costs over time.
Is this ammo safe to use with a sound suppressor?
Yes. Underwood rates this 9mm+P+ load as safe for use with suppressors. The supersonic velocity and jacketed bullet design are suppressor-compatible, so you can train or carry suppressed without concerns.
What's in the box—how much ammo do I get?
Each box contains 20 loaded rounds of 9mm+P+ ammunition. The case option includes 10 boxes (200 rounds total), which is convenient for serious shooters or those building a supply for regular range work or duty carry.
