The Underwood 357 Sig 115gr JHP is purpose-built defensive ammunition designed for law enforcement, armed security, and civilian self-defense professionals who demand reliable terminal performance. This cartridge delivers the penetration and expansion characteristics required in duty-grade applications where target consistency and stopping power are non-negotiable. The 357 Sig cartridge itself bridges the performance gap between 9mm and .40 S&W, offering faster velocities with reduced recoil compared to larger bore options—making it the preferred choice for agencies and operators who need superior ballistics without excessive muzzle rise or follow-up shot delay.
Underwood's 115-grain Nosler jacketed hollow point (JHP) projectile achieves a muzzle velocity of 1550 feet per second, generating impressive energy transfer on target while maintaining controlled expansion through intermediate barriers. The Nosler JHP design features a precision-engineered cavity that promotes consistent mushrooming across a range of barrier conditions—critical for defensive loads where performance cannot be compromised by clothing, drywall, or vehicle glass. This ammunition is loaded to exacting specifications to ensure uniform chamber pressures and shot-to-shot velocity consistency, essential factors for accuracy and reliability in duty weapons or defensive pistols where performance variance can impact shot placement under stress.
This 20-round box configuration is ideal for law enforcement duty loads, security training courses, and defensive practice regimens where shooters maintain ready reserves. The Underwood 357 Sig 115gr JHP is compatible with all standard .357 Sig platforms, including SIG Sauer P226 and P229 duty weapons, as well as numerous aftermarket and OEM .357 Sig pistols. Hand-loaders and ammunition enthusiasts value Underwood's consistent quality and competitive pricing, while duty officers appreciate the ballistic reliability and terminal performance that meets or exceeds most law enforcement ammunition standards for service use.
