UNDERWOOD AMMO 876 XTREME DEFENSE PLATINUM 9MM+P 90 GR SOLID MONOLITHIC 20 RNDS

AMMUNITION WILL SHIP WITH ADULT SIGNATURE REQUIRED.

Underwood Ammo Xtreme Defense Platinum 9mm Luger +P 90 gr Solid Monolithic (876) is a lead-free, solid copper defensive handgun load engineered to produce a massive permanent wound cavity through optimized nose flute geometry rather than traditional hollow point expansion. This 20-round box of 9mm +P personal defense ammunition is built for concealed carry shooters, home defense pistol owners, and anyone who demands consistent, barrier-independent terminal performance from a standard capacity 9mm platform.

Special Features

• The Xtreme Defender nose flute is precision-machined into solid copper, creating a radial hydraulic pressure system on impact that forces tissue outward and produces a permanent wound cavity diameter that outperforms conventional expanding hollow point designs at equivalent velocity
• Penetration depth is engineered to reach up to 18 inches, placing this load within the depth range widely cited by defensive ammunition testing protocols as effective for personal protection
• The solid copper construction eliminates the expansion failure risk associated with traditional hollow point bullets when passing through heavy clothing, sheet metal, glass, or other intermediate barriers before reaching the target
• Nickel-plated brass cases resist corrosion during extended carry in humid conditions and in magazine pouches, and the bright finish makes it easy to visually confirm chambered rounds during a chamber check
• The Platinum Edition designation identifies this load with a distinctive case coating that sets it apart visually from standard Xtreme Defender loads while maintaining identical ballistic performance
• This load is rated safe for suppressor use, making it compatible with threaded 9mm pistol hosts without concern for pressure-related function issues

Practical Benefits

• At 1,475 fps from a 9mm +P loading, this round delivers a flat, fast trajectory that keeps point of aim closely aligned with point of impact at typical defensive engagement distances, reducing the need for holdover correction
• The lead-free, solid copper construction makes this load a practical option for indoor ranges with lead restrictions and for shooters who prefer to keep lead exposure low in carry and training ammunition
• Nickel-plated brass and Boxer primers cycle reliably through striker-fired and hammer-fired 9mm semi-automatic pistols, and the +P pressure rating is compatible with any firearm rated for +P ammunition by its manufacturer
• Reloadable cases give handloaders the option to reclaim and reload spent brass, reducing the per-round cost of a premium carry load over time
• The 20-round box provides enough rounds to establish function reliability in your specific pistol and rotate your carry supply without the cost commitment of a bulk purchase
• If you carry a 9mm pistol and want a defensive load that performs through barriers, skips the dependence on expansion mechanics, and delivers serious terminal energy, the Underwood Xtreme Defense Platinum 9mm +P (876) gives your carry pistol a technically advanced and proven defensive option

Underwood Ammo Xtreme Defense Platinum 9mm Luger +P 90 gr Solid Monolithic (876) is a capable tool for concealed carry shooters who want a barrier-blind, lead-free defensive load with a permanent wound cavity profile that stands apart from conventional 9mm hollow point ammunition.
