Underwood Ammo Xtreme Defender .40 S&W 140gr Solid Monolithic - Box or Case

The Underwood Ammo Xtreme Defender in .40 S&W is a personal-defense loading built around a heavy-for-caliber 140-grain Solid Monolithic copper bullet designed to penetrate tough barriers and hold its mass on impact. Driven to a 1200 fps muzzle velocity and seated in Nickel-Plated Brass cases, this round is engineered to deliver deep, controlled penetration from compact carry pistols through full-size duty guns.

The Xtreme Defender forgoes a traditional jacketed hollow point in favor of a single-piece solid copper construction. With no lead core and a hard copper striking surface, the monolithic bullet retains weight on impact and feeds smoothly through standard pistol magazines, making it a clean, consistent option for everyday carry and home defense.

Underwood loads this ammunition with premium components, measured charges, and inspected cases. The Nickel-Plated Brass cases resist corrosion, chamber smoothly, and feed reliably across the full range of .40 S&W service pistols.
