Underwood 38 Spl 100gr - Xtreme Defender 20rd 10bx/cs

The Underwood 38 Spl 100gr Xtreme Defender 20rd ammunition is purpose-built for defensive carry in revolvers and compact pistols where capacity and stopping power are non-negotiable. Developed in partnership with Lehigh Defense, this load represents a significant advancement in terminal ballistics for the .38 Special platform—a caliber still relied upon by law enforcement agencies, security professionals, and responsible civilians seeking reliable personal protection. At 100 grains, this projectile weight strikes an optimal balance between velocity management and penetration control, delivering consistent performance across barrel lengths from snubnose to medium-length cylinders.

The Lehigh Defense Xtreme Defender bullet features a solid copper construction with a unique fluted nose cavity—engineered to produce controlled expansion and minimal over-penetration in common barriers without compromising velocity or energy transfer. Factory chrono data shows 1200 feet per second muzzle velocity and 320 foot-pounds of muzzle energy, generating ballistic performance that exceeds conventional 38 Special loadings by a measurable margin. The nickel-plated brass casings offer superior corrosion resistance and provide visual distinction in the magazine, aiding in rapid visual confirmation during reload operations. Each box contains 20 rounds—the industry standard for defensive ammunition storage and carry systems.

This load is ideal for shooters who carry snubnose revolvers, backup pistols, or manage firearms with modest velocity potential where premium projectile design becomes critical to terminal effectiveness. The 38 Special platform remains common in uniformed security, plainclothes carry, and legacy duty weapons, making this ammunition a practical choice for those prioritizing proven reliability over modern cartridge alternatives. Function has been verified across various revolver platforms, from vintage models to contemporary production firearms. The 20-round box format integrates seamlessly with standard speed loader pouches, tactical vests, and ammunition storage systems used by professionals and prepared civilians.
