Underwood 9mm 124gr JHP Ammo - 20rd Box Premium Defense Rounds

The Underwood Ammo 114 9mm 124gr Jacketed Hollow Point delivers maximum stopping power through precision-engineered expansion and deep penetration. This premium defensive ammunition combines flash-suppressed powder with nickel-plated brass cases for reliable feeding and extraction in any conditions.

What Makes This Different

Underwood's 124-grain JHP projectiles achieve consistent 1150+ fps velocities from standard barrel lengths, producing over 360 ft-lbs of energy at the muzzle. The carefully engineered hollow point cavity expands reliably through heavy clothing and intermediate barriers while maintaining weight retention above 95%. Unlike mass-produced defensive loads, each cartridge undergoes individual quality inspection before packaging.

Key Features

• 124-grain jacketed hollow point bullets optimized for controlled expansion
• Nickel-plated brass cases resist corrosion and enhance feeding reliability
• Flash-suppressed powder reduces muzzle signature in low-light situations
• Consistent velocities within 25 fps standard deviation for predictable performance
• Compatible with all 9mm Luger chambered firearms including compact pistols
• Boxer-primed cases suitable for reloading applications
• 20-round boxes with 10-box case quantities for bulk purchasing

Extensive ballistic testing demonstrates reliable expansion from 3-inch to 5-inch barrel lengths across temperature ranges from -20°F to 140°F. The 124-grain weight provides optimal balance between penetration depth and expansion diameter for personal defense scenarios. Law enforcement agencies specify similar loadings for duty carry due to consistent terminal performance through automotive glass and heavy fabric barriers.
