G2 Research CIVIC 45 ACP Civic Duty 45 ACP 164 Gr Copper Expansion Projectile. G2 Research has taken its innovative Trocar design of the solid copper R.I.P. fragmenting projectile and adapted it to the G2 Research Civic Duty expanding self-defense round. The Civic Duty round defeats barriers as effectively as the R.I.P. and expands 2.5 times its initial diameter after coming into contact with a fluid medium. The Civic Duty round expands to transfer 100percent of its energy to the target. The Civic Duty Round retains 99.9percent weight inside the intended target without concern of over penetration in CQB situations.Features:Extreme Expansion 6-8? penetration Solid Copper / Lead Free projectile Specifications for G2 Research Civic Duty 45 ACP 164 grain Copper Expansion Projectile Brass Cased Pistol Ammunition: Manufacturer: G2 Research Ammunitions Caliber: .45 ACP Number of Rounds: 20 Bullet Type: Copper Expansion Projectile Bullet Weight: 164 grain Cartridge Case Material: Brass Muzzle Velocity: 1020 ft/s Application: Protection Primer Style: Centerfire Fabric/Material: Copper Package Contents: G2 Research Civic Duty 45 ACP 164 grain Copper Expansion Projectile Brass Cased Pistol Ammunition G2 Research CIVIC 45 ACP Civic Duty 45 ACP 168 Gr Copper Expansion Projectile
