Underwood 38spl+p 140gr - Xtreme Penetrator 20rd 10bx/cs

The Underwood 38 Special +P 140 Grain Xtreme Penetrator ammunition delivers reliable stopping power for law enforcement, armed security, and civilian self-defense applications where barrier penetration and consistent performance are non-negotiable. Offered in convenient 20-round boxes with 10 boxes per case, this load represents a serious choice for professionals and serious shooters who demand ammunition engineered to perform when it matters most. The +P pressure rating indicates this round generates higher velocity than standard 38 Special, translating to improved ballistic performance from typical service-length revolvers and compact pistols.

Underwood's Xtreme Penetrator design prioritizes deep, straight-line wound channels through intermediate barriers—a critical consideration for duty rounds that must perform through heavy clothing, vehicle glass, or other real-world obstacles. The 140-grain projectile strikes an optimal balance between velocity and weight retention, maximizing energy transfer while maintaining the controlled expansion needed for precision shot placement. This bullet geometry has been proven in law enforcement testing protocols and delivers the kind of ballistic consistency that separates purpose-built duty ammunition from commodity rounds. The +P rating requires verification that your firearm is rated for +P pressures—most modern steel-frame revolvers and quality semi-automatic pistols handle this load without issue, but confirmation is essential before shooting.

This ammunition suits investigators, security personnel, and armed citizens carrying service revolvers or compact 38 Special semi-automatics who prioritize terminal performance over volume. The 10-box case format makes it practical for range testing, duty rotation, or building reliable reserves. Recoil management remains reasonable despite the +P designation, allowing faster follow-up shots without excessive muzzle flip—a real advantage in dynamic scenarios. Verify your firearm's pressure rating before purchasing; standard 38 Special-only firearms are not compatible with +P ammunition.
