Underwood 9mm Luger +p+ 124gr - Bonded Jhp 20rd 10bx/cs

Underwood 9mm Luger +P+ 124gr Bonded JHP ammunition delivers professional-grade stopping power for law enforcement, military, and civilian defensive carry. This round is engineered for personnel seeking reliable, barrier-blind performance in duty or self-defense scenarios where controlled expansion and deep penetration are non-negotiable. The bonded jacketed hollow point design ensures consistent terminal ballistics regardless of intermediate barriers.

The 124-grain projectile achieves 1,300 feet per second muzzle velocity and 465 foot-pounds of energy, generating the velocity threshold necessary for reliable hollow point expansion while maintaining structural integrity. Speer's bonded construction mechanically locks the jacket to the core, preventing jacket separation and core fragmentation during expansion—a critical factor in duty use where shot placement authority and penetration consistency directly impact reliability. Nickel-plated brass casings reduce friction in the chamber, lower extraction resistance, and enhance corrosion resistance, extending service life in field storage and humid environments. Each box contains 20 rounds, with 10 boxes per case for standardized duty or training supply.

This cartridge suits 9mm Luger platforms rated for +P pressure levels, including Glock duty pistols, Smith & Wesson M&P series, SIG Sauer P-series, and modern duty revolvers. The +P+ rating delivers superior velocity and energy density compared to standard 9mm, making it the choice for departments and operators who prioritize terminal performance without compromising reliability. Verify your firearm's manual for +P compatibility before use; most modern duty weapons accept this load without issue, though older or compact frames may require review.
