Taser International's XP Cartridge is a less-lethal ammunition product designed for enhanced clothing penetration. The XP Cartridge uses a probe design that is 256 percent the mass of Taser’s regular probes with a barbed tip that is 175 percent the length of Taser's standard probe. The XP Cartridge can compress or move clothing barriers 140 percent greater than Taser's standard projectile with no additional medical risks.
