Underwood Ammo Xtreme Defense ammunition in .32 ACP (brand part no. 850) is a defensive load engineered around reliable expansion and stopping power. Underwood Ammo manufactures this load to consistent tolerances, so every box performs the same as the last. At the heart of this load is the 55 gr bullet, matched to the .32 ACP platform shooters already run. In our handgun ammunition lineup, this is the Underwood Ammo load built for that job.

Key Specifications

• The bullet weighs 55 gr, sized for the terminal performance this load is built around.
