The Underwood 40 S&W 165gr Bonded JHP ammunition is purpose-built for defensive carry and duty use where reliable expansion and barrier penetration are essential. This ammunition is trusted by law enforcement, armed security professionals, and serious civilian shooters for its consistent performance through common intermediate barriers—clothing, drywall, and vehicle glass—while maintaining energy transfer to the target.
The 165-grain bonded projectile features a jacket that is molecularly fused to the lead core, preventing separation on impact and ensuring controlled expansion even at subsonic velocities or after barrier defeats. This construction maximizes wound channel consistency and minimizes the risk of over-penetration in populated environments. The hollow-point cavity is engineered for reliable expansion across a wide velocity window, which is critical for the variance found in .40 S&W platforms.
Each box contains 20 factory-loaded rounds, with 10 boxes per case, making it suitable for high-volume shooters or agency procurement. This ammunition is designed to cycle reliably in most standard .40 S&W firearms, including compact and full-size platforms, but users should always verify compatibility with their specific firearm. The bonded construction also resists environmental degradation, ensuring dependable performance in various conditions.
