The Flashball Defence Weapon. French non-lethal ‘defense’ weapon apparently has the stopping power of a .38 Special. Which it achieves by chucking soft rubber balls at the target. Very fast. So probably like being thumped by an angry Mike Tyson? €346.84 says it’ll hurt. A lot.
The stopping power of the 28 g soft rubber ball (200 joules at 2.5 meters) is equivalent to that of a 38 Special and achieves the same effect as the punch of a champion boxer. On impact the ball crushes and releases its power over an area of approximately 35 cm2. For short distance use (at 12 meters, impact pattern is 30 cm).
