The Underwood Ammo 940 Xtreme Defense Platinum 10mm Auto 115gr Solid Monolithic round is engineered for shooters who want consistent performance from a modern defensive handgun load. This Platinum Edition pairs a solid copper Xtreme Defender projectile with nickel-plated brass cases to deliver reliable feeding and clean extraction in a wide range of 10mm pistols.

Designed around an optimized fluted nose, this 115 grain bullet drives to a penetration depth of up to 18 inches while creating a large permanent wound cavity, even after passing through common barriers such as wallboard or automotive glass. With a muzzle velocity of 1700 fps and flash-suppressed powder, it is well suited for personal protection, medium game hunting, and serious training where controllable recoil and repeatable accuracy matter. Underwood Ammo’s focus on precision manufacturing and innovative bullet design is evident in every cartridge.
