The Underwood XTP .380 ACP offers a genuinely hot load for this compact caliber. Loaded to 1025 feet per second, it's a significant step up from typical factory .380 rounds, which helps the 90-grain Hornady XTP hollow point bullet expand more reliably in real-world scenarios. You're getting a carefully balanced combination of components: the proven XTP bullet design paired with Underwood's proprietary powder formulation and nickel-plated brass casings.
The nickel-plated brass matters more than it might sound. Unlike standard brass, it won't tarnish during storage or when exposed to leather and moisture from a holster. That translates to smoother feeding in semi-automatic actions and less hassle if you reload. The flash-suppressed powder is another practical touch—it helps preserve your vision in low-light situations, which is a real consideration for defensive carry.
The XTP bullet design includes strategic features built for the .380's constraints. The hollow point design has a reinforced jacket that shields the rim, reducing the risk of feeding issues. Notches around the jacket's perimeter are engineered to weaken it at precise points, allowing more consistent expansion. The jacket thickens toward the base, which helps ensure the bullet expands uniformly rather than separating. At 1025 fps from a 3.8-inch barrel, this load puts the XTP right in its performance window.
People who carry .380 pistols often choose between penetration and expansion—there's no perfect answer at this caliber. The Underwood load strikes a middle ground that appeals to users of compact pistols like the Bodyguard and LCP. Reliability through real guns is the priority here, and the nickel-plated brass and XTP combination cycles cleanly in the firearms people actually carry. Each box contains 20 rounds, and the ammunition is new production, non-corrosive, and loaded into boxer-primed reloadable brass.
The Underwood XTP is loaded hotter than typical factory .380 rounds, pushing 1025 fps compared to the standard 950-1000 fps range. This extra velocity helps the 90-grain XTP bullet expand more reliably during expansion, which is important in a caliber known for borderline penetration. The nickel-plated brass and flash-suppressed powder are additional features built for real-world carry and defensive use.
Yes. Users report good reliability through popular compact carry guns like the Ruger LCP, Bodyguard, and similar pistols. The nickel-plated brass feeds smoothly, and the XTP hollow point design includes reinforced features to reduce feeding issues. That said, it's always smart to test defensive ammunition through your specific firearm before relying on it.
Yes, the ammunition uses new production, boxer-primed nickel-plated brass that's fully reloadable. The nickel plating actually makes reloading easier—it reduces sizing friction and won't tarnish like regular brass, making cleanup simpler between rounds.
The powder formulation is designed to reduce visible muzzle flash when fired, which helps you maintain your night vision if you ever need to use the firearm in low-light conditions. This is a practical feature for defensive carry ammunition that you won't find in all .380 loads.
