Underwood Ammo 9mm +P is engineered for shooters who demand superior performance, whether for target practice, competition or hunting. Loaded to higher pressure levels, this round delivers exceptional accuracy, consistency and stopping power - but be sure your firearm has the necessary chamber support before use. If you're unsure about compatibility, consult a gunsmith or contact us directly. At this time, we do not recommend use with True Precision P365 conversion barrels. Designed for precision and terminal performance, this round features Nosler Sporting Handgun bullets with an alloy jacket that enhances game-taking ability. Its tapered jacket ensures maximum accuracy, while the dual form-fitted pure lead core guarantees reliable expansion across a broad velocity range. Nickel-plated brass casings provide smooth feeding, superior corrosion resistance and effortless clean-up, maintaining their pristine condition even in storage. As with all Underwood Ammo, flash-suppressed powder minimizes muzzle flash, preserving your vision in low-light scenarios. Rigorously tested in real-world conditions, this high-performance ammunition is built to exceed expectations when it matters most.
