Underwood 380 ACP 90gr XTP Jacketed Hollow Point

Underwood 380 ACP 90gr XTP Performance Ammunition

This is serious defensive ammunition built on proven principles. Underwood pairs Hornady's eXtreme Terminal Performance bullets with carefully formulated propellant to deliver a round that performs when it matters most.

Bullet Performance

Hornady XTP Design: The 90-grain XTP bullet is engineered for controlled expansion and deep terminal penetration. This balance is critical—you need reliable expansion for stopping effectiveness, but also sufficient penetration to reach vital areas through intermediate barriers.

Case Construction

Underwood uses nickel-plated brass casings, which offer distinct advantages over standard brass:

• Enhanced feeding across all firearm actions
• Superior corrosion resistance compared to traditional brass
• Resistance to tarnishing during storage and when exposed to moisture, leather, or other metals
• Easier cleanup if you reload

Powder Selection

Flash-suppressed powder is standard in all Underwood loads. This formulation preserves your night vision if you must use your firearm in low-light conditions—a real-world consideration that separates quality defensive ammunition from the rest.

Field-Tested Reliability

Every load is tested in actual firearms that shooters own and carry. This isn't laboratory ammunition; it's proven in the real world with the guns you depend on.
