Underwood Ammo 9mm +P 147gr JHP Defense Rounds - 20rd Box

The Underwood Ammo 9mm +P 147 grain Jacketed Hollow Point delivers enhanced stopping power through premium construction and optimized ballistics. This defensive ammunition combines heavy bullet weight with +P pressure loading to maximize energy transfer while maintaining controllable recoil.

What Makes This Different

Underwood's 147 grain JHP operates at +P pressures to achieve superior expansion and penetration compared to standard pressure loads. The heavy bullet design provides deeper penetration through barriers while the jacketed hollow point construction ensures reliable expansion upon impact. Flash-suppressed powder reduces muzzle flash in low-light situations, making this ammunition ideal for defensive applications where follow-up shots matter.

Key Features

• 147 grain jacketed hollow point bullet for maximum expansion
• +P pressure loading generates 1000+ fps muzzle velocity
• Flash-suppressed powder reduces muzzle signature
• Nickel-plated brass cases resist corrosion and aid extraction
• Compatible with all 9mm Luger firearms rated for +P ammunition
• Precision-loaded for consistent accuracy and reliability
• 20 rounds per box, 10 boxes per case (200 total rounds)

This ammunition excels in defensive scenarios where reliable expansion and adequate penetration are critical. The 147 grain bullet weight reduces felt recoil compared to lighter +P loads while maintaining subsonic velocities in most barrel lengths. Law enforcement and civilian defenders appreciate the consistent performance across various pistol platforms, from compact carry guns to full-size service pistols.
