Glaser Pow'RBall .40 S&W 135gr Defensive Ammunition

Glaser Pow'RBall Defensive Ammunition

The Pow'RBall represents a thoughtful solution to a persistent problem in defensive shooting: reliable expansion in modern semiautomatic pistols combined with consistent feeding and performance.

Design Innovation

This round features Glaser's patented construction: a gilding metal jacket surrounding a lead core shaped into a distinctive V-cavity, topped with a polymer ball crimped securely in place. The design addresses multiple performance requirements simultaneously.

Performance Characteristics

• Muzzle Velocity: 1325 fps
• Muzzle Energy: 526 ft-lbs
• Bullet Weight: 135 grains
• Caliber: .40 Smith & Wesson
• Package: 20 rounds per box

How It Works

The polymer ball serves three critical functions. First, it improves aerodynamics during flight by dispersing air around the projectile, enhancing ballistic performance. Second, it enhances feeding reliability in semiautomatic pistols—a significant advantage over traditional hollow points. Third, it controls expansion by delaying the initial impact response, allowing the bullet to penetrate several inches before the ball is displaced, exposing the V-shaped cavity and triggering proper expansion.

Defensive Advantage

The polymer cap also protects the hollow point cavity from being plugged by clothing or other materials during penetration, ensuring the round expands as designed. This makes Pow'RBall ammunition a reliable choice for personal protection in real-world defensive scenarios.
